The d->cylinders created will be overriden by libdivecomputer parsing,
resulting in 0, 1 , may be 2 cylinders depending on DC data. This is not
what we want when importing a divelog, because we will miss all hand
entered tanks.
BTW, using get_cylinder() on tank number bigger than created, results in
a NULL pointer and a crash.
As we can't foresee how many tanks (or even it's positional numbers in
log) a diver has used, the full 10 tanks supported by SmarTrak can be
easily created and parsed using get_or_create_cylinder(), and unused
cleaned later.

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.

As Berthold points out, a failure to match the site or location index
will result in an infinite loop with previous patch.
With this one the loop will end after reading the last table row even if
no idx is matched. But ... If we asume this situation is possible the
retrieved data would be wrong, and ending the function without filling
the site structure is mandatory too.

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.

Since the UUID will be overwritten on save and is only used on save
and load, set it only on save or load. For other created dive sites,
leave the UUID field uninitialized.
This means that the UUID will change between saves. Let's see how
the git saver handles that.

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.
After this change, a simple search for dive_site_table reveals all
places where the global dive site table is accessed.

add_to_string() frees the original string that is passed in. This
should therefore not be of "const char *" type, as the contents
of the string *will* be modified (or more precisely: destroyed).

Rename
- dive_get_insertion_index() -> dive_table_get_insertion_index()
- unregister_dive_from_table() -> remove_from_dive_table()
- get_idx_in_table() -> get_idx_in_dive_table()
- sort_table() -> sort_dive_table()
This will make it more straight-forward to generate these functions
from macros.

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.

As a first step in removing dive-site uuids, change the interface
of the get_dive_site_*() functions to return pointers instead
of uuids. This makes code a bit more complicated in places where
the uuid is extracted afterwards (needed NULL check). Nevertheless,
these places should disappear once pointers instead of uuids are
stored in the dive-structures.

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).

We can allocate fixed size arrays for smartrak tables as its size can
be known in advance. Simply reading table->num_rows is too dangereous
as smartrak tables have "holes" commonly. This is, they can look like:
Idx | Txt
1 | blablabla
2 | blebleble
4 | blobloblo
table->num_rows would give us 3, but we need to allocate 4 to get an
array like:
|0|blablabla |1|blebleble |2| |3|blobloblo
as the idea is to use the table index to reference the array data.

In most cases we can not foresee the maximum number of data of a given
type. It can be quite low or really big (a concerned diver can store
thousands of different fishes in Fish table).
Moving from arrays, where size has to be preset, to linked lists seems
the more logical option.
Here we set a (very limited) data structure, just an index and a text
fields following the format of most SmartTrak tables. Some special
table, like Buddy, needs a bit of processing before placing the data in
the list.

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]).

For different reasons some used functions aren't portable or simply are
not included in mingw. This includes index, rindex, strptime, and
timegm.
A workaround for this is needed, if we want to build for windows using
mingw based mxe environment. This patch does:
- drops index and rindex in favor of strchr and strrchr
- substitute strptime with a sscanf parsing
- emulate timegm with a private func smtk_timegm()
- remove definitions needed by strptime

SmartTrak's bookmarks work in the same fashion Subsurface's do. The user
may set a bookmark while underwater or set it just on the divelog
software.
At this time we are parsing those set in the DC twice, as we get one
from libdivecomputer and another from smarttrak's database.
This patch just checks if we have a bookmark event downloaded by
libdivecomputer which has the same time that the one parsed from the
.slg file. If so, merge the names taking the one from smarttrak.
Text from smarttrak is preferred because the user may have entered some
interesting note there and libdivecomputer's name is just "bookmark".

Until now, we did the cylinder import based on its initial pressure (a
tank without pressure is an unused tank). Based in this assumption, we
just dropped those tanks whose initial press was 0, losing user
introduced tank definitions and getting some duplicities due to one
cylinder being numbered (e.g.) 2 by libdivecomputer and 3 by SmartTrak.
The new workflow is: get every single tank reported by SmartTrak (giving
preference to libdivecomputer parsed data), then clean the cylinder
table reverse order, dropping tanks without description and init or end
pressures, and checkig them against the previous cylinder to do a merge,
if they look the same, and try to avoid duplicities.
The new logic assumes a heavier workload for the benefit of lower data
loss (e.g. a user may get his/her tanks descriptions despite he/she
hasn't recorded their pressures because forgot the values or had an issue
with the gas transmitter).

The cylinder info is built one by one. This way, instead of passing dive
and tank number parameters, just passing a pointer to the tank been
worked seems preferable.
It also introduces lrint() in the function to round the doubles values
obtained from libmdb for tank size and workingpressure.

Framed in a full rework of the cylinders info import management, this
funcs will be used in next patches.
Functions merge_cylinder_type(), merge_cylinder_mix() and
merge_cylinder_info(), have been shamelessly copied from dive.c as they
have been removed by 162767aa dated 2017-03-11 just when I was going to

Macros MERGE_MAX() and MERGE_MIN() have just been copied from dive.c,
but they could be moved to dive.h so they could be used elsewhere if
needed.

User can manually add bookmarks on the profile display of SmartTrak.
These are stored in a table with column names which made me think of
cartesian spatial coordinates. In the end the X coordinate is the time.
This makes possible to build subsurface events in those moments of the
dive. The other interesting data is just the text entered by the user.
