The simplified filter-widget doesn't present lists of existing values
with counts. Thus, a whole slew of count_dives_with_*() functions
can be removed.

In 302f6adb79681da3fe53336f1e4c7525f46fd47d dive-splitting was made
undo-able. To this goal, the dive-splitting functions were split in
two types: Those that operate directly on the divelist and those that
only allocate the dives. The former are not in use anymore, therefore
remove them. Since only the latter remain, remove the "_dont_insert"
appendix of the name.

Currently, when selecting "Load media files even if time does not
match the dive time", the media are added to *all* selected dives.
Instead add it to the closest dive.
This seems like the less surprising behavior. Of course now if the
user really wants to add a media file to multiple dives, they will
have to do it manually.
To avoid a messy interface, this is solved by moving the iterate-
over-selected-dives loop to the core. Thus, a helper-function can
be made local to its translation unit.

The only remaining use of the tripflag was to mark dives that
were removed explicitly from a trip, i.e. shouldn't be autogrouped.
Therefore replace the enum by a simple boolean.
Currently, there is no way of unsetting the notrip flag. But this
shouldn't result in a user-visible change.

The distinction between ASSIGNED_TRIP and IN_TRIP was used to
prefer non-autogenerated trips on merging of dives. But owing
to bit rot this seem to have worked only partially anyway:
The IN_TRIP field was set in create_and_hookup_trip_from_dive()
and immediately overwritten in add_dive_to_trip() called
in the next line.
Instead, use the trip->autogen flag to check for priority and
remove the ASSIGNED_TRIP flag alltogether.

With the fixed sematics of get_gasmix to return the new gasmix for
the time of a gas switch (added comments to make this clear), in the
OTU calculation we need the previous gasmix for the interval up to the
current time.

This fixes a subtle bug introduced in 5c4569247a31c which
unified two functions finding the gasmix at a given time
during the dive. There was a slight difference, though:
Does a gaschange exactly at that time count or not? For
the planner to work, the answer has to be in the affirmative.

Replace the UUID reference of struct dive by a pointer to dive_site.
This commit is rather large in lines, but nevertheless quite simple
since most of the UUID->pointer work was done in previous commits.

This changes more of the dive-site interface to return pointers
instead of UUIDs. Currently, most call sites directly extract
UUIDs afterwards. Ultimately, the UUIDs will be generally replaced
by pointers, which will then simplify these callers.

Instead of having people treat latitude and longitude as separate
things, just add a 'location_t' data structure that contains both.
Almost all cases want to always act on them together.
This is really just prep-work for adding a few more locations that we
track: I want to add a entry/exit location to each dive (independent of
the dive site) because of how the Garmin Descent gives us the
information (and hopefully, some day, other dive computers too).

On dive computer copy, the extra data (a list of key/value pairs)
was simply copied as a pointer. This worked because the list was
never freed nor modified. Copy and free the list on dive computer
copy and free, respectively.
This made it necessary to move the STRUCTURE_LIST_* macros up in
the dive.c file.

In commit e5dca8228e6b60cac5957726700c66d0565c064e a fixed order
of the arguments to merge_dives() was introduced: first dive old,
second dive downloaded. This made the dl variable, which pointed
to the downloaded dive useless. One instance was forgotten, which
led to a null-dereference.

sanitize_cylinder_type(), which is indirectly called from fixup_dive(),
had ft^3 -> mliter conversion code, which was executed on the
condition "xml_parsing_units.volume == CUFT".
But nowhere in the code base would xml_parsing_units.volume ever be
set to non-metric. Moreover, xml_parsing_units reflects the units
of the latest parsed XML file, but fixup_dive() is called in numerous
contexts not related to XML parsing. Therefore, the whole piece of
code seems highly questionable.
Remove this code.

copy_dc_renumber() is an internal function to copy dive computers
and renumber the cylinders. Since only the structure was copied,
in the case of multi-dc dives, the merged dives shared the same
computer. If one of them was freed, use-after-free crashes would happen.

In commit 8c2383b4952fa22d41745d29484462ed6a67112b dive merging was
changed to not modify the original dive. On import, dives were then
merged and the original deleted. The merge_weightsystem_info() was
not adapted accordingly (deep copy of string instead of pointer),
leading to a use-after-free crash.
Resolve this by doing a deep copy.

For undo, it is crucial that commands don't modify existing dives.
Unfortunately, dive merging would write into the data-structures
of the to-be-merged dives. To prevent it from doing so, make the
input dives const-pointers.
This led to a whole cascade of functions that had to take const
and significant churn.

For this, an output-parameter was added to the backend merge_dives()
function. When non-zero, instead of adding the merged dive to
the preferred trip, the preferred trip is returned to the caller.
Since the new UndoObject, just like the delete-dives UndoObject,
needs to remove/readd a set of dives, the corresponding functionality
was split-off in a helper function.

For this, the core functionality of the split_dive() and
split_dive_at_time() functions were split out into new
split_dive_dont_insert() and split_dive_at_time_dont_insert(),
which do not add the new dives to the log. Thus, the undo-command
can take ownership of these dives, without having to remove them
first.
The split-dive functionality is temporarily made desktop-only
until mobile also supports "UndoObjects".

Dive importing is now performed via a distinct table which is
merged into the main dive table. Thus, it is known which of the
dive is new and which is old. This information can now be
implicitely encoded in the parameter-position of merge_dive()
[i.e. pass old as first and new as second dive].
This makes marking of downloaded dives via a flag unnecessary.

Currently, we can only delete dives that are indexed in the main
dive table. In the future, we will have to delete dives outside
of this table (e.g. for undo). Therefore, split out the free_dive()
function from delete_single_dive(), which takes an index into
the main dive table.
In the process, adopt the dive freeing-code from clear_dive(),
which frees more data than the code in delete_single_dive().
This potentially fixes a memory-leak.

On import of dive media, the timestamp is read from the
metadata to check if the image belongs to the selected dives.
The pictures are then listed in a dialog.
Currently, the metadata is read twice if images are outside
of a dive: once in picture_check_valid() and if it turns
out that the picture is not valid again in picture_get_time()
to display the proper timestamp.
Even though metadata-extraction is reasonably fast, this is
a bit of an embarrassment.
Instead, read the timestamps only once in the constructor of
the dialog and from then on only used these timestamps. Keep
the timestamps in a QVector. Rename the picture_check_valid()
function to picture_check_valid_time() and pass a timestamp
instead of a filename.

The merge_one_sample() function adds a sample to the destination
dive if dives are merged. For long periods between samples at surface
depths, it adds a surface interval.
To decrease the number of global objects, make the sample structure
non-static. Of course, initialization of an on-stack structure is
slower. Therefore move it into the corresponding if. Thus, the
structure will be initialized only once per surface-interval.

Commit f5b11daffd6f240268ce78d72c64be43670988ea changed gasmix
arguments and return values to be passed by value instead of
using pointers.
Notably, get_gasmix() is fed a default-value and returns a
new value. In the old code, NULL was passed in in a first
loop iteration and non-NULL was always returned in the first
iteration. Thus, an equality comparison of passed-in an
returned gasmix would always fail in the first loop iteration.
The new code passed in air as default. Now if air was also
returned, then the matching gases were not calculated in
calculate_sac(). To revert to the old behavior, pass in
an invalid gasmix.
Moreover, give names to the invalid and air gasmixes.

This is another entry in the series to make more things
"const-clean" with the ultimate goal of merge_dive() take
const pointers.
This concerns functions taking pointers to events and
the fallout from making these const.
The somewhat debatable part of this commit might be
that get_next_event() is split in a two distinct
(const and non-const) versions with different names,
since C doesn't allow overloading. The linker should
recognize that these functions are identical and remove
one of them.

Accessor-functions without noticeable logic, such as depth_to_bar()
can trivially be made "const-clean".
Moreover, let get_dive_location() return a "const char *". The
non-const version must have been an oversight, as the caller
must not free() or overwrite the string.

In a previous commit, the get_gasmix_* functions were changed to
return by value. For consistency, also pass gasmix by value.
Note that on common 64-bit platforms struct gasmix is the size
of a pointer [2 * 32 bit vs. 64 bit] and therefore uses the
same space on the stack. On 32-bit platforms, the stack use
is probably doubled, but in return a dereference is avoided.
Supporting arbitrary gas-mixes (H2, Ar, ...) will be such an
invasive change that going back to pointers is probably the
least of our worries.
This commit is a step in const-ifying input parameters (passing
by value is the ultimate way of signaling that the input parameter
will not be changed [unless there are references to said parameter]).

There were two functions for getting gas-mixes at a certain timestamp:
- get_gasmix() for repeated queries.
- get_gas_at_time() for a single query.
Since the latter is a special case of the former, simply call
the former in the latter. Moreover, rename to get_gasmix_at_time()
for consistency.
Replace on get_gasmix() call, which was outside of a loop by the
corresponding get_gasmix_at_time() call.

Currently, get_gasmix_from_event() and get_gasmix() return pointers
to either static or to (possibly changing) dive data. This seems like
a dangerous practice and the returned data should be used immediately.
Instead, return the gasmix by value. This is in preparation of
const-ifying input parameters of a number of core functions, which
will ultimately let the merge() function take const-arguments in
preparation of undo of dive-merging.
On common 64-bit systems gasmix (two "int"s) is the size of a pointer
and can be returned in a register.
On 32-bit systems a pointer to the struct to be filled out will be
passed.
Since get_gasmix() now returns a value, the first invocation is
tested by a NULL-initialized "struct event *". Document this in
a comment.

Conceptually, the doFilter() functions shouldn't modify the dive

dive_getUniqID() is used to create unique dive ids, which are
stable during application lifetime. It was passed a dive, checked
that the id was not set (if it was that it is know to the application)
and set a new id (in contradiction to its name!) if it hadn't any.
There were three callers:
alloc_dive(): called the function on a zeroed dive struct.
fixup_dive(): called the function only if the dive had a 0 id.
MainWindow::setupForAddAndPlan(): called the function on a zeroed dive
struct.
Thus, in all three callers the id is guaranteed to be zero and
the whole keeping-track-of-ids logic is moot. Remove the logic,
don't pass a dive struct to dive_getUniqID() and move the function
to the C-backend.

When we split a dive in two, we keep the dive computer ID for the dive,
but we should update the actual _time_ of the split dive to match the
split.
And when we look for "are these the exact same dives", we should check
not only that the dive computer dive ID matches, but also that the dive
computer time matches, so that we don't consider two parts of a dive
that has been split to be obviously the same dive.

The dive splitting was completely wrong, because we checked the time of
the previous sample by doing
sample[i - 1].time.seconds
which is entirely wrong. The 'sample' variable is the *current* sample,
so the time of the previous sample is simply
sample[-1].time.seconds
Alternatively, we could have started from the first sample, and done
dc->sample[i - 1].time.seconds
but mixing the two concepts up just gets you a random sample pointer
that is likely not a valid sample at all, and obviously does not have
the right time at all.
As a result, dive splitting was pretty much random. Sometimes it worked
purely by mistake, because the rest of the logic was right (ie we _had_
found the right point where we reached the surface in the dive etc, the
"previous sample time" was simply used to decide if the surface interval
was sufficient to split the dive up).
