992ad2fa27 Dive sites: simplify nr_of_dives_at_dive_site()
1) The second parameter (selected_only) was always false. Therefore,
   remove it.

2) Simplify the function by simply returning the reference count.

Instead of setting dive->dive_site directly, call the
add_dive_to_dive_site() and unregister_dive_from_dive_site()
functions. In the parser this turned out to be a bit tricky.

c22fd9f4fd Dive sites: prepare for dive site ref-counting
Add a dive site table to each dive site to keep track of dives
that have been added to a dive site. Add two functions to add
dives to / remove dives from dive sites.

Since dive sites now contain a dive table, the order of includes
had to be changed: "divesite.h" now includes "dive.h" and not
vice-versa. This caused some include churn.

31291b1c56 Dive site: set UUID only on save or load
Since the UUID will be overwritten on save and is only used on save
and load, set it only on save or load. For other created dive sites,
leave the UUID field uninitialized.

This means that the UUID will change between saves. Let's see how
the git saver handles that.

ac1602f512 Dive site: ensure that no two dive sites have same UUID
We absolutely want to avoid dive site with the same UUID.
But that could happen when reimporting a log where the
dive sites diverged.

Therefore, on adding a dive site to a table, change the UUID
if it already exists. Since dives are associated to dive
sites with pointers, this should have no negative impact.

82af1b2377 Undo: make undo-system dive site-aware
As opposed to dive trips, dive sites were always directly added
to the global table, even on import. Instead, parse the divesites
into a distinct table and merge them on import.

Currently, this does not do any merging of dive sites, i.e. dive
sites are considered as either equal or different. Nevertheless,
merging of data should be rather easy to implement and simply
follow the code of the dive merging.

f6e7bdc5ef Dive site: add dive site table parameter to dive site functions
To enable undo of dive site functions, it is crucial to work
with different dive site tables. Therefore add a dive site table
parameter to dive site functions. For now, always pass the global
dive site table. Thus, this commit shouldn't alter any functionality.

After this change, a simple search for dive_site_table reveals all
places where the global dive site table is accessed.

4d06ddd723 Dive sites: don't delete unused dive sites on save
Unused dive sites were deleted on save. This clashed with the undo
system in the following scenario:

1) Delete single-use dive site.
2) Save (dive site deleted)
3) Undo (reference to freed dive site)

Therefore, as a quick-fix, keep the referenced dive site around.
Note that this also means that empty dive sites must not be
deleted, as it might refer to a dive in the undo system. Instead
only clear references to empty dive sites in the global dive
table. Factor this functionality out, as it was common to the
XML and git savers.

28e3413ff6 Add 'location_t' data structure
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).

08827cc5f6 Parser: fix leakage of dive-site and dive data
Dive site data was collected in "cur_dive_site", which was then
merged into an existing or a new dive site. But only the struct
dive_site pointed to by "cur_dive_site" and the taxonomy data
were freed, not the textual data such as name or description.
Therefore, split out the approrpriate free-ing from the
delete_dive_site() function and call that instead of a simple
free().

A similar situation occured for dives that would not be added
to the dive-table because they were deemed incomplete. Use
free_dive() here instead of a simple free() too.

8815f77ea0 Dive site: use own copy of taxonomy in dive-site-edit widget
The dive-site-edit widget uses a copy of the to-be-edited site
to compare with old values. Generally, this seems overkill
(the original dive-site can be used for such a comparison).
But one place where it can't simply be removed is the taxonomy,
because the widget needs a place to store the unsaved data.

Change the code to use an explicit taxonomy structure instead
of the one provided in the copy. This should ultimately allow
removal of the latter.

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.

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.

We used to always create a new dive site structure when loading dive

That is completely bogus, because it can (and does) create duplicate

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.
