e85ecdd925 Introduce helper function empty_string()
There are ca. 50 constructs of the kind
  same_string(s, "")
to test for empty or null strings. Replace them by the new helper
function empty_string().

e762d2a23e core: free() in a safe way, reverse geolookup unstability
A simple one line change that solves (for me) numerous hard crashes
when adding geo tags by reverse lookup from the dive site edit
screen. This is one of those crashes that is might not be
reproducible on any platform, or even between different builds
on one platform.

This said, I found that the free() on line 99 of divesitehelpers.cpp
tried to free pointers to random data, ie. not pointing to valid
taxonomy category strings. And those pointers where simply caused by
freeing the string earlier, and leaving the pointer around. So, this
change is nothing more than setting the just freed pointer to NULL,
to allow free() to be called later safely.

c4e1e96032 divesite.c: use union in create_divesite_uuid()
The return produces a warning about "strict-aliasing rules".
Use a union to fit the hash and the uint32_t into the same
block of memory, which obeys the GCC strict-aliasing rules.

8c77c15dd8 git storage: invalidate cache on merge dive site
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.

Fixes: #939

Makes it clearer that these are buffers and not integers
like `ds->uuid`.

21d78121ad Don't add separate country field, use taxonomy
The more I looked at the code that added the country to the dive site,
the more it seemed redundant given what we have with the taxonomy.

Sometimes we might want to be able to copy just the taxonomy.

2b06a0b223 Fix potential double/float to int rounding errors
Not using lrint(f) when converting double/float to int
creates rounding errors.
This error was detected by TestParse::testParseDM4 failure
on Windows. It was creating rounding inconsistencies
on Linux too, see change in TestDiveDM4.xml.

Enable -Wfloat-conversion for gcc version greater than 4.9.0

2e77a22e2c Fix dive site string merging
If the second dive site doesn't have a particular string, but the first
one does, we did the wrong thing and created a result string like

   (first dive site string) or ((null))

which is not useful.  We should just use the first dive site string
as-is.

4a550e4d7d Properly handle dive sites loaded from XML
We used to always create a new dive site structure when loading dive
site data from XML.

That is completely bogus, because it can (and does) create duplicate
dive sites with the same UUID.  Which makes the whole UUID pointless.

So instead, look up the existing dive site associated with the UUID
loaded from the XML, and try to merge the data properly if we already
had dive site information for that UUID.

7be962bfc2 Move subsurface-core to core and qt-mobile to mobile-widgets
Having subsurface-core as a directory name really messes with
autocomplete and is obviously redundant. Simmilarly, qt-mobile caused an
autocomplete conflict and also was inconsistent with the desktop-widget
name for the directory containing the "other" UI.

And while cleaning up the resulting change in the path name for include
files, I decided to clean up those even more to make them consistent
overall.

This could have been handled in more commits, but since this requires a
make clean before the build, it seemed more sensible to do it all in one.
