A very very trival fix, for a mysterious issue. When loading
GPS fix data from the server, the string date was parsed with
the format "yyy-M-d". And no, the "yyy" is no typo here, but
was the reason that data from the read from server got a
1/1/1970 data. And when a user decided to upload that data
to the server again, we ended up with 2 copies of the
GPS fix. One with correct data (as originally saved), and
one new with the bogus date.
In order to het rid of those weird 1/1/1970 GPS fixes, users
will have to remove them by hand.

To access a QMap<> entry, the value() function is used with a sentinel
as default value. If the sentinel is returned, the code assumes that
the searched for entry doesn't exist.
Make this code more idiomatic by using an iterator and testing for
end().
This fixes a compiler warning, because only one of the elements of
the sentinel was initialized, but the remaining elements were
copied. Harmless, because the code would exit early if it found
the sentinel. Still not nice.
While redoing this function, the entry-not-found message was improved

In hindsight a very simple bug to fix, but it requires some
knowledge on the inner workings of our git storage. The changes
on merge of dive sites were simply not saved (completely) because
the git storage code has a cache that we need to invalidate
selectively (ie. for the dive we just gave a new dive site uuid)
to get things finally embedded in the overall commit.
The main reason this bug went unnoticed for more than 2 years is
that most people use the XML/SSRF format (where this problem is
non exsistent), and dive site merging is probably not a very
much used feature either.

Commit 46004c39e2 introduces a new field in the logbook outputs
(depth of a cylinder). While in XML the depth unit is stored with a space
between value and unit (m), in our git storage, the unit m is without
space. As the git storage parser uses a space to separate individual
key/value pairs, the erroneously saved space results in parsing warnings
when opening the logbook.
The unwanted space is normally saved just after download of a new dive
from the dive computers, so all desktop-git-storage uses are affected,
and more worrying, mobile beta users.

Internal floating point (FP) calculations should be performed using double
unless there is a very good reason. This avoids headaches with conversions.
Indeed, the vast majority of FP calculations were already done using double.
This patch adapts most remaining calculations. Not converted where things
that were based on binary representations and variables which weren't used
anyway.
An analysis of all instances follows:
core/plannernotes.c, l.404:
This was a comparison between two floats. On the left side, first an integer
was cast to float then multiplied with and integer and divided by a constant
double. The right hand side was an integer cast to a float. Simply divide by
1000.0 first to convert to double and continue with calculations. On the right
hand side, remove the cast, because the integer will be implicitely cast to
double for comparison. This conversion actually emits less instructions,
because no conversion to double and back is performed.
core/planner.c, l.613:
Same analysis as previous case.
subsurface-desktop-main.cpp, l.155:
A local variable representing the version OpenGL version. Turn this into
integer logic. Not only does this avoid dreaded FP rounding issues, it also
works correctly for minor version > 10 (not that such a thing is to be
expected anytime soon).
abstractpreferenceswidget.[h/cpp]:
A widget where the position is described as a float. Turn into double.
desktop-widgets/divelogexportdialog.cpp, l.313:
total_weight is described as float. Use double arithmetics instead. This
instance fixes a truncation warning emitted by gcc.
The function isCloudUrl() was only called in one place, parse_file().
But, isCloudUrl() could only return true if the filename was of the
git-repository kind (url[branch]). In such a case, control flow would
never reach the point where isCloudUrl() is called, since
is_git_repository() returns non-NULL and the function returns early.
Therefore, remove this function. Moreover, adapt the affected if-statement
by replacing "str && !strcmp(str, ...)" with the more concise
"same_string(str, ...)".

Each preferences object owns its string members. In three cases, pointers
were copied instead of strings, leading to (in the best case) dangling
pointers if the user edited values:
1) In the GET_TXT macro in core/prefs-macros.h
2) In the PreferencesDialog::defaultsRequested() method
3) In main() of the mobile version
This patch fixes these issues, by using copy_string() or copy_prefs()
as appropriate.
The only reason that the old code didn't crash regularly is that the
default_prefs object was only used at startup and defaultsRequested()
is (at the moment?) dead code.

In the old implementation there were two static C-style strings, filename
and path, which were initialized to NULL and filled on first call of
the function (i.e. singletons).
There is no sense in having two static variables indicating whether
this function was called previously. Moreover, there is no point
in remembering filename accross function calls, because it is not
used once path is set to a non-NULL value.
Therefore, make the filename variable non-static and calculate it only on
first invocation (as indicated by a NULL path). Moreover, free() the filename
variable after its use to fix a memory leak of the old code.
The windows code is slightly different in that the temporary filename is
not dynamically allocated.

This tries to remove subtle ownership issues. When copying preferences

This patch attempts to make the code more consistent by turning

Tests showed that writing as short and reading as bool is handled
gracefully by the Qt variant code. Therefore, an upgrade should not
cause user-visible changes to their settings.

Stefan Fuchs points out that sometimes you get cylinder duplication when
you merge dives, particularly with a planned dive. For example, if we
had different manual pressures in the two different dives, the cylinders
will be kept separate.
But that also means that we don't want to plot the pressures from those
other cylinders that came from another dive and are now associated with
another dive computer.
