Recently the QStrings were replaced by std::strings in device.cpp
so that they can be accessed from C-code. However, libstd being
modelled after C, constructing a std::string from a NULL pointer
leads to a crash.
Fix one case where this was overlooked.
Moreover, replace a null-pointer check by empty_string(), to
treat NULL and "" equally.

Because of subsequent changes there is no clean way to just revert the changes
introduced in commit 8b36cf1051 ("desktop: offer different colors for info tab
titles"), so this manually removes the parts we don't need anymore.
This also restores a tooltip value that was inadvertantly removed in that
commit.

Add a preference option to set the color of the text on the information tab to
either MediumBlue, LightBlue or Black. The last two of these colors are meant
to enable areadable font contrast on displays with dark mode.
The choice is saved with the other preferences.
[Dirk Hohndel: this isn't really about dark mode, so changed many of the types
and variable names, changed the user visible texts, and
addressed some whitespace issues]

When encountering a <weight> tag, we would parse into the last
weightsystem. However, we only create weightsystems when
encountering <weightsystem> tag. Therefore, this code would
either crash or overwrite the previous weightsystem.
Instead, create a new weightsystem for each <weight> tag.
Moreover, make sure that inside a <weightsystem> tag a
weightsystem actually exists. This should be the case,
but who knows...?

When dives were merged on import, they were not unregistered
from their dive site and trip before being deleted. Thus, these
tables had stale pointers, which would ultimate lead to crashes.

This used to be a copy of QSysInfo. However, once the requirement
was raised to Qt5.4, this was replaced by a subclass of the original
QSysInfo - which made the whole file mostly obsolete.
Just use QSysInfo directly where needed.
Only for windows.c, which can't call directly into Qt, keep the
isWin7Or8() helper function.

For multiple-choice constraints we use a bit field of type
uint64_t. This means we theoretically support up to 64 items.
Currently use at most seven.
Coverity complained (correctly) that we use the expression
"1 << x" to generate the bitfields. However 1 is a 32-bit
literal on most platforms, which makes this undefined
behavior for x >= 32. Change the integer literal to 64-bit
1ULL.
Moreover, when detecting items with an index >= 64, don't
even attempt to set the according bit, since this is
undefined behavior and the compiler is free to do as it
pleases in such a case.

Since dive.c is so huge, split out divecomputer-related functions
into divecomputer.[c|h], sample.[c|h] and extradata.[c|h].
This does not give huge compile time improvements, since
struct dive contains a struct divecomputer and therefore
dive.h has to include divecomputer.h. However, it make things
distinctly more clear.

The function
1) was misnamed: it determined the time of the first selcted dive.
2) had only one caller.
3) would crash if there was no selected dive.
Let's just fold the functionality into the caller. It's a one-liner
anyway.

Desktop does not use mark_divelist_changed() anymore - all is done
via the undo machinery. Therefore move this function (and its

Ultimately, it probably should be removed from there as well, but

Technically get_dive() could return a nullptr. The existing code made sure the
argument passed to get_dive() was one that always would result in a valid dive
pointer being returned. The new code is only slightly less efficient but allows
a static code analysis to easily see that we don't derefence NULL pointers here.
On some level this change is unnecessary. But it's also not wrong.

In the specuial case of suunto, where we may add a device directly
instead of via dive->dc, add the device to the provided table.
The caller will then pass on the new device to the undo system.
This makes downloading finally really undoable (at least I
hope so). So far, the dives and dive sites were removed, but any
new device remained.
However, when setting the device-id via serial, we now have
to check both, the global and the downloaded list of devices.

In one weird case (suunto), the code in libdivecomputer.c
generates a device node directly instead of going the usual
way (setting the data in the dc-structure of the imported
dive). It is unclear to me whether that has to be that way,
as it depends on the chronological order of callbacks to
event_cb() and dive_cb().
Therefore add a device_table pointer to device_data_t
so that the downloader can add the device to this table. This
only adds the pointer, but does not yet use it in the
downloading code.

In analogy to the xml-parser add a device-table to git's parser-state.
Currently this is unused. In upcoming commits the git parser will
then be changed to add device nodes in this table instead of the
global device table. The long-term goal being to detach the
parsers from global state and to make dive-import fully undoable.

Add a device_table parameters to Command::importTable() and
add_imported_dives(). The content of this table will be added
to the global device list (respectively removed on undo).
This is currently a no-op, as the parser doesn't yet fill
out the device table, but adds devices directly to the global
device table.

If we want to avoid the parsers to directly modify global data,
we have to provide a device_table to parse into. This adds such
a state and the corresponding function parameters. However,
for now this is unused.
Adding new parameters is very painful and this commit shows that
we urgently need a "struct divelog" collecting all those tables!

The XML-parameter code is a mess. Ownership is unclear. Allocation
and freeing of strings is in different functions. Sometimes
only every second string is free()d, because keys are not copied.
But this is done inconsistently. The caller has to know how
many parameters the callee may add.
Instead, let's add a small helper-struct that uses C++ memory
management, but exports a C-API. The array for the XML-library
is generated on the fly.
This is only the implementation, the old code is not yet replaced.

Apparently libdc gives us copies of strings. The API is very
scary, because (at least according to my reading of the code),
the key/value pair may be stored in a cache. Thus on free()ing
the string in the cache becomes invalid and we must not access
it twice. Very obscure.

Recently, the sorting of the devices was changed to be
