f297d9f91e Fix picture loading
Signed vs unsigned comparisons are such a pain. Since we want offsets to
be +/- 30 minutes around the dive we need to allow negative offsets - but
duration_t was defined as uint32_t.

d97c49ba39 When copying dives, make copies of samples/events in first DC
We carefully copied the dive computers and their samples and events, but
only for the second and later DCs. For the first DC we simply copied the
pointers but not what they were pointing at. So when the copied dive was
freed, those pointers in the original went to freed memory.

Not good.

47f9f59c1a UI restructure: add clone_dive helper
This is kind of the inverse to copy_dive(). Instead of duplicating all the
data that the dive points to, it moves it to a new struct dive and zeroes
out the old one so there are no two sets of pointers to these data.

a221a6e9f5 UI restructure: use a global variable to hold the dive we show / edit
There is massive confusion about what we display when and where and which
dive structure (or pointer to a dive structure) contains which information
at which stage. This is the first step towards restructuring all of this.

This creates a global variable displayed_dive which at any point in time
should be what is displayed on screen (both in the profile and in the
maintab). It removes the editedDive concept from MainTab.

1d09ce2ce2 Picture loading: only add the pictures to "reasonable" dives
If the picture has a timestamp that was within 30 minutes of the start and
finish of the dive, we take it. Otherwise we don't.

If the timestamps of the images are off, the time shift dialog allows the
user to fix this.

And with this patch the user can select all the dives of a trip and all
the pictures they took on the trip and the "right thing" will happen.

1604299a5b Picture handling: change data structure to store offset instead timestamp
It makes no sense to store a 64bit time stamp with every picture. Even the
32bit offset (in seconds) from the dive start is WAY overkill. But
switching to that makes the code much more simple in a number of spots.
And makes what is saved to the XML file easier to read, too.

This will replicate the information (filename, latitude and longitude) for

c539c8f861 Remove the .used member of the cylinder structure
Instead calculate this information on the fly, taking into account all
dive computers on the dive in questions.

There is one wrinkle to this - previously we abused the '.used' member to
make sure that a manually added cylinder didn't disappear the moment it
was added (think of the workflow: you add a cylinder, then you add a gas
change to that cylinder -> right after you add it it is unused and would
not be shown).

I am thinking that we might have to add the "manually_added" property to
the properties that we store in XML / git.

ef4705070f Create a 'remove_event' function that removes an event.
The logic of removing the event was in the UI, and this makes
the code harder to test because we need to take into account
also the events that the interface is receiving, instead of
only relying on the algorithm to test.

so, now it lives in dive.h/.c and a unittest is easyer to make.

7821b87983 Use the last 'diveid' when merging dives for one dive computer
When we merge two dives into the same dive because a divecomputer had
incorrectly considered it two separate dives (due to surface time within
the dive) we should pick the dive ID from the later dive to be the
diveid of the resulting merged dive.  Otherwise we might re-download the
(now merged) partial dive.

This is a rather unusual special case, but it actually hit me with the
Uemis on my last dive in Palau: Chandelier Cave has multiple surface
points where you can spend time admiring the cave above water, and the
Uemis (but not my Suunto's) decided that the dive was actually four
short dives back-to-back.

818542eeca Don't merge divecomputers if we know they are different
When merging dives, if we know for sure that the dive computers are
different, don't merge them into one (by interleaving the data), but
instead keep both as separate dive computers in the same dive.

This fixes a bug when due to a faulty download the same dive from two dive
computers looks quite different. They don't get merged automatically
(which is fine - they are quite different), but when manually merging
them, we of course want one dive with two dive computers, not one dive
with one merged dive computer.

eb47b2a8d8 Get rid of crazy empty tag_list element at the start
So this is totally unrelated to the git repository format, except for
the fact that I noticed it while writing the git saving code.

The subsurface divetag list handling is being stupid, and has a
initial dummy entry at the head of the list for no good reason.

I say "no good reason", because there *is* a reason for it: it allows
code to avoid the special case of empty list and adding entries to
before the first entry etc etc.  But that reason is a really *bad*
reason, because it's valid only because people don't understand basic
list manipulation and pointers to pointers.

So get rid of the dummy element, and do things right instead - by
passing a *pointer* to the list, instead of the list. And then when
traversing the list and looking for a place to insert things, don't go
to the next entry - just update the "pointer to pointer" to point to
the address of the next entry. Each entry in a C linked list is no
different than the list itself, so you can use the pointer to the
pointer to the next entry as a pointer to the list.

This is a pet peeve of mine. The real beauty of pointers can never be
understood unless you understand the indirection they allow. People
who grew up with Pascal and were corrupted by that mindset are
mentally stunted. Niklaus Wirth has a lot to answer for!

But never fear. You too can overcome that mental limitation, it just
needs some brain exercise. Reading this patch may help. In particular,
contemplate the new "taglist_add_divetag()".

689fe36030 Initial implementation of git save format
This saves the dive data into a git object repository instead of a
single XML file.

We create a git object tree with each dive as a separate file,
hierarchically by trip and date.

NOTE 1: This largely duplicates the XML saving code, because trying to
share it seemed just too painful: the logic is very similar, but the
details of the actual strings end up differing sufficiently that there
are tons of trivial differences.

The git save format is line-based with minimal quoting, while XML quotes
everything with either "<..\>" or using single quotes around attributes.

NOTE 2: You currently need a dummy "file" to save to, which points to
the real save location: the git repository and branch to be used.  We
should make this a config thing, but for testing, do something like
this:

	echo git /home/torvalds/scuba:linus > git-test

to create that git information file, and when you use "Save To" and
specify "git-test" as the file to save to, subsurface will use the new
git save logic to save to the branch "linus" in the repository found at
"/home/torvalds/scuba".

NOTE 3: The git save format uses just the git object directory, it does
*not* check out the result in any git working tree or index.  So after
you do a save, you can do

     git log -p linus

to see what actually happened in that branch, but it will not affect any
actual checked-out state in the repository.
