The way we export the profile image (as direct export but
also used for printing) is that we render the profile
from the screen to a Pixmap and save that to a file. Unfortunately
this results in very bad resultion and a blurred image.
This is an attempt to improve that situation but it's still far
from perfect: Rather than a QPixmap and grab, I now use a QImage
(where I can set the size) and render, and indeed the picture resolution
(when vied at fixed size) get's better this way. The disadvantage
is that icons get smaller at the same rate und so
there is a natural limit on how big we can get. Maybe somebody
with better Qt knowledge can take off from here. In my opinion
this is already a step in the right direction.

WLog is a Win32 based ancient shareware program whose target was:
1) fully support divelogs coming from DataTrak (DOS or Win)
2) fill some meaningful data which wasn't supported by Uwatec software
3) have a more user-friendly GUI than Datatrak had
The problem achieving goals 1) and 2) at the same time was solved by
adding a complementary file with .add extension and - mandatory - same
base name than .log file (including directory tree).
This .add file has a fixed structure composed of a 12 bytes header,
including file type check and Nº of dives following; then a fixed 850
bytes size for each dive in the log file. Data fields size and position
are fixed inside these blocks and heavily zero padded, so they are easy
to parse.
A serious restriction imposed to the WLog user was *Do not edit the logs
with other software than Wlog*; this was due the order of dives in .log
file being the same than the order of dives in .add file. Thought you
could show a WLog divelog in Datatrak, editing it resulted in mixing all
extended data for dives following the edited one.
Thus, we have to trust files are correct and is to the user ensure this
is so. If extended data are mangled, they are mangled in WLog too and we
are not trying to fix the mess, just importing.
On the technical side, we try to be smart about tank names as neither
DataTrak nor WLog record them. So we just take the first tank in users
list matching the volume recorded in WLog.
For weights we add a translatable "unknown" string as an empty string
results in weight not being shown in subsurface-mobile (which could be a
reportable issue, BTW).

When the dive has no explicity salinity, our conversion
between pressure and depth assumed salt water. Make this
explicity by using the corresponding macro.
When the planner starts and no salinity is set explicity,
set the water type chooser to salt water to reflect

This new option allows a user to select a new destination tank for an
existing "Gas Change" event. This is useful when Subsurface's heuristics
get tanks wrong after an import from a divecomputer. The use-case arose
from sidemount divers with air-integrated transmitters as well as carrying
a deco tank.

When setting up a dive for replanning, we ignored zero length segments as those
tend to be generated by gas changes. But it is possible to enter those in the
planner and the replanning should not ignore those. So be
more clever about gas changes. Let's add 10 seconds so we are not at two depths
at the same time and help since add_stop also does not like zero length
segments (it thinks we are trying to replace a waypoint).

While this code was added as I was trying to work through issues with a BLE

So instead of handling the services as we find them, let's instead wait until

get_cylinder(d, i) is more readable than d->cylinders.cylinders[i].
Moreover, it does bound checking and is more flexible with respect to
changing the core data structures. Most places already used this accessor,
but some still accessed the cylinders directly.
This patch unifies the accesses by consistently switching to get_cylinder().
The affected code is in C++ and accesses the cylinder as reference or
object, whereas the get_cylinder() function is C and returns a pointer.
This results in funky looking "*get_cylinder(d, i)" expressions.
Arguably still better than the original.

getFormattedCylinder() is a helper function to format a list
of cylinders. It had that weird logic that it would skip
cylinders without description unless it is the first, which
would instead be written as "unkown".
The reason was the old statically sized cylinder array,
where it wasn't clear if a cylinder was actually in use.
This became obsolete when switching to a variable size
cylinder array. Firstly, all cylinders in the array were added
by the user. Secondly, we now also support dives without
cylinders, i.e. the first cylinder is not any different from
the rest.
Thus, remove the logic and format any cylinder without
description as being of type "unknown".

0249e12 split up the dive import logic in multiple steps. Thereby,
the one of the conditions for renumbering the imported dives (is
the last old dive numbered) got messed up: The first number of the
new dive was compared to the total number of old dives, which makes
no sense.
- Simply check for the number of the last existing dive (if any).
- Don't remember the number of old dives - the original table is
not modified anyway.

We are usually showing pressures with localized group separator. And we made a
total mess out of things when then re-parsing those values. This caused us to
ignore start and end pressures in Subsurface-mobile when those were entered in
psi and included a group separator:
2,900psi was turned into 2.900psi which we then rounded to 0 mbar.
This fixes the problem by asking Qt to do the right thing instead of doing
stupid separator magic.

The merge_events() function was subtly and not-so-subtly broken in a
couple of ways:
- in commit 8c2383b49 ("Undo: don't modify source-dives on merge"), we
stopped walking the event list after we merged the first event from a
dive when the other dive computer had run out of events.
In particular, this meant that when merging consecutive dives, the
second dive only had the first event copied over to the merged dive.
This happened because the original code just moved the whole old list
over when there was nothing left from the other dive, so the old code
didn't need to iterate over the event list. The new code didn't
realize that the pointer movement used to copy the whole rest of the
list, and also stopped iterating.
In all fairness, the new code did get the time offset right, which
the old code didn't. So this was always buggy.
- similarly, the "avoid redundant gas changes" case was not handled for
the "we ran out of events for the other dive computer" case.
This fixes both issues.

Smtk2ssrf has a segfault which matches quite well glibc's
CVE-2019-6488 (except for the x32 part).
It came from a call to memcpy in mdb_ole_read() func, used to get the
header and the profile of a dive from the database.
May be it could be fixed in libmdb but Mdbtools project has been stalled
for the past 5 years so ...
The segfault seems to be triggered by an empty profile in the first dive
in the database (a pretty common case in older Aladin DCs due to their
little memmory). The only special thing here is the fact it's the first
dive in the database structure (not the first by its index).
We can avoid the crash if we don't call mdb_ole_read_full() func on zero
sized profile field.
The problem here is we can't get the size of the fields and build the
MdbColumn in the same roud. Happily we just need the MdbColumn struct
for the dive profile and header. So, we can change the previous approach
using MdbColumns through almost all functions to a simpler one using the
already bounded strings by smtk_open_table() and just using the
col[n]->bind_pointer in the main function where the columns are built to
be used by mdb_ole_read_full().

For some reason we suddenly started logging the GPS fixes in UTC instead

like an easy enough fix, since the GPS fix being reported is by
definition "right around now". So using gettimezoneoffset() with the
current time seems "good enough".

When removing the MAX_CYLINDERS restriction, the layout of the
pressure readings was changed from a (cylinder,sample) to a
(sample,cylinder) scheme. I.e. previously there were one cylinder
block for each sample, then one sample block for one cylinder.
However, after populating the samples, the array size was reduced
to the actual number of used samples. With the new layout this
breaks indexing. Therefore, restore the old layout.
