These just make no sense. Since the value is copied, it
has no meaning to the caller whether the function can
change the value (and vice versa for return types).

Instead of accessing the cylinder table directly, use the get_cylinder()
function. This gives less unwieldy expressions. But more importantly,
the function does bound checking. This is crucial for now as the code
hasn't be properly audited since the change to arbitrarily sized
cylinder tables. Accesses of invalid cylinder indexes may lead to
silent data-corruption that is sometimes not even noticed by
valgrind. Returning NULL instead of an invalid pointer will make
debugging much easier.

Instead of using fixed size arrays, use a new cylinder_table structure.
The code copies the weightsystem code, but is significantly more complex
because cylinders are such an integral part of the core.
Two functions to access the cylinders were added:
get_cylinder() and get_or_create_cylinder()
The former does a simple array access and supposes that the cylinder
exists. The latter is used by the parser(s) and if a cylinder with
the given id does not exist, cylinders up to that id are generated.
One point will make C programmers cringe: the cylinder structure is
passed by value. This is due to the way the table-macros work. A
refactoring of the table macros is planned. It has to be noted that
the size of a cylinder_t is 64 bytes, i.e. 8 long words on a 64-bit
architecture, so passing on the stack is probably not even significantly
slower than passing as reference.

When exporting dive sites, the dive sites to be selected were collected
in the C-core. But that doesn't have access to the selected dive sites
if in dive site mode. Therefore, collect the dive sites in C++ and
pass down to the core. Use a std::vector to avoid memory management
woes.

is_dive_site_used() had a "selected" parameter. If true it would
return whether the given dive site had a selected dive. Turns
out all callers had this parameter set to true. Therefore, replace
by a simplified function without the "selected" parameter and
give the function an appropriate name.

It turns out that the dive site saving was subtly but horribly buggy.
To save the value of the dive site, it did
show_utf8_blanked(b, t->value, " value='", "'/>\n", 1, anonymize);
which looks sane on the face of it, but the problem is that it puts the
final closing xml marker in the 'append this at the end' case.
That means that if the value is empty, the value won't be saved, but
neither will the closing tag. Resulting in an xml line that looks like
this:
<geo cat='3' origin='0' <geo cat='5' origin='0' value='Other name'/>
where the first geo tag was saved without the ending marker.
That then makes all the xml nesting entirely wrong, and the whole file
fails to save.
Now, the code around it does check that 't->value' is not NULL, but it
doesn't check for a value that is empty or all spaces (which also will
make 'show_utf8()' just skip it.
Fix it by saving the end marker separately:
show_utf8_blanked(b, t->value, " value='", "'", 1, anonymize);
put_format(b, "/>\n");
so that the xml is valid even if the goe marker value wasn'r.

Replace the fixed-size weightsystem table by a dynamically
relocated table. Reuse the table-macros used in other parts
of the code.
The table stores weightsystem entries, not pointers to
weightsystems. Thus, ownership of the description string is
taken when adding a weightsystem. An extra function adds
a cloned weightsystem at the end of the table.

While testing the cylinder type saving fix, I noticed that the RBT
saving was broken. Instead of saving RBT whenever it changed, we'd save
it when it was non-zero. Which doesn't match the git save format, and
also doesn't match what we do when loading an xml file (where we default
to the previous RBT value, and a sample RBT will modify it).

Steve Williams reported a crash when saving a previously loaded dive as
xml, and gave a gdb backtrace.
It turns out that if we can't parse the cylinder use type (OC, diluent,
oxygen, unused) we initialize the cylinder use to an invalid type, and
then when we save it, we mess up.
Fix it up by doing proper limit checking before accessing the
"cylinderuse_text[]" array when saving.

Add a dive site table to each dive site to keep track of dives
that have been added to a dive site. Add two functions to add
dives to / remove dives from dive sites.
Since dive sites now contain a dive table, the order of includes
had to be changed: "divesite.h" now includes "dive.h" and not
vice-versa. This caused some include churn.

To enable undo of dive site functions, it is crucial to work
with different dive site tables. Therefore add a dive site table
parameter to dive site functions. For now, always pass the global
dive site table. Thus, this commit shouldn't alter any functionality.

places where the global dive site table is accessed.

Currently, all trips are kept in a linked list. Replace the list
by a table in analogy to dive_table. Use this to keep the trip_table

Unused dive sites were deleted on save. This clashed with the undo
system in the following scenario:
1) Delete single-use dive site.
2) Save (dive site deleted)
3) Undo (reference to freed dive site)
Therefore, as a quick-fix, keep the referenced dive site around.
Note that this also means that empty dive sites must not be
deleted, as it might refer to a dive in the undo system. Instead
only clear references to empty dive sites in the global dive
table. Factor this functionality out, as it was common to the
XML and git savers.

Instead of having people treat latitude and longitude as separate

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).

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]).

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.

In the last commits, the canonical-to-local filename map was made
independent from the image hashes and the location of moved images

unused (except for conversion of old-style local filename lookups).
Therefore, remove the hashes in this commit. This makes addition

This provides for reading of divemode change events from dive logs
and for writing them to dive logs. This applies to xml and git
divelogs. Divemode change events have the following structure:
event->name = "modechange"
event->value = integer corresponding to enum dive_comp_type (dive.c),
reflecting the type of divemode change (OC, CCR, PSCR, etc).
In the dive log file, the event value is written as a string that
corresponds to each of the enum values, e.g.
<event name='modechange' divemode='OC' />
This xml is also read from the dive log file and translated to an
appropriate value of event->value.
The file diveeventitem.cpp was udated to reflect this new way of
dealing with divemode change events.

This patch allows the planner to save the last manually-entered
dive planner point of a dive plan. When the plan has been saved
and re-opened for edit, the time of the last-entered dive planner
point is used to ensure that dive planning continues from the same
point in the profile as was when the original dive plan was saved.
Mechanism:
1) In dive.h, create a new dc attribute dc->last_manual_time
with data type of duration_t.
2) In diveplanner.c, ensure that the last manually-entered
dive planner point is saved in dc->last_manual_time.
3) In save-xml.c, create a new XML attribute for the <divecomputer>
element, named last-manual-time. For dive plans, the element would
now look like:
<divecomputer model='planned dive' last-manual-time='31:17 min'>
4) In parse-xml.c, insert code that recognises the last-manual-time
XML attribute, reads the time value and assigns this time to
dc->last_manual_time.
5) In diveplannermodel.cpp, method DiveplannerPointModel::loadfromdive,
insert code that sets the appropriate boolean value to dp->entered
by comparing newtime (i.e. time of dp) with dc->last_manual_time.
6) Diveplannermodel.cpp also accepts profile data from normal dives in
the dive log, whether hand-entered or loaded from dive computer. It
looks like the reduction of dive points for dives with >100 points
continues to work ok.
The result is that when a dive plan is saved with manually entered
points up to e.g. 10 minutes into the dive, it can be re-opened for edit
in the dive planner and the planner re-creates the plan with manually
entered points up to 10 minutes. The rest of the points are "soft"
points, shaped by the deco calculations of the planner.
Improvements: Improve code for profile display in dive planner
This responds to #1052.
Change load-git.c and save-git.c so that the last-manual-time is
also saved in the git-format dive log.
