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.

Previously we built arrays for the tables each time we parsed a dive.
Now we simply build the lists once, and use them in each dive parsing.

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]).

As Lubomir pointed out in his patch for datatrak.c, the format option %m
for sscanf doesn't work in mingw/windows. Fortunately it's unnecessary
as dates are dropped and we just get times.

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.

hdr_buffer pointer was not always allocated (just on dc dives), but was
always freed.
This should cause a crash while processing a manually added dive (or a dive
whose dc model couldn't be stablished), but not always does, crashes only
if the pointed memory hasn't been previously allocated. In most cases causes
memory corruption, which goes easily unnoticed as it is correctly freed in
next parse run.
This means, obviously, I have some work TODO fixing leaks with valgrind.

Libmdbº:xturns localized strings while parsing the data bases. This is
bad for time calculations as we may end with different strings formats
(e.g. en_US vs almost the rest of the world). Solution is simple: set a

SmartTrak is a Windows based propietary dive log software by Uwatec, which has
been the reference software for every Scubapro/Uwatec IRda based devices,
ranging from Smart to Galileo. It has just been recently that began to be
substituted by newer softwares like LogTrak and JTrak (these only supports
Galileo or newer devices and don't import SmartTrak's .slg files).i
SmartTrak also supports importing dives from older DataTrak software (oldest
Aladin series, serial based DCs) so most divers using Scubapro/Uwatec products
have probably their dives registered in this log, even those who have just moved
to newest Scubapro/Uwatec DCs.
SmartTrak is based in MS Access database with support for recreational and
technical dives up to 10 tanks, trimix (in later versions, prior versions had
support for just 3 tanks with Nitrox) and SCR/CCR.
In Linux, MsAccess databases are supported via libmdb which in turn depends on
libglib2, so this work has a hard dependency on these two libraries.
Libmdb sees very little (or null) development activity today so it can be
considered a mature library, which, in my opinion, makes it independent of
progresses of libglib2, this way, the tool should build on most Linux
distributions, even oldest ones (well, this will actually be false because of
the other dependencies of Subsurface).
Final note: It hasn't been until very recently that libdivecomputer has included
support for some of the data downloaded from Galileo devices, even today
understanding some of these data is WIP (e.g. alarms, are interpreted as
bookmarks at this moment, and there is a lot of noise coming from the
tanks/gases area in libdc)
