249b82f6dc pictures: make delta-time a 64-bit int
When adjusting picture times, the offset in seconds is stored in a
32-bit int. Make it a 64-bit int. Sounds crazy, because why would
you want to move the pictures by more than 70 years?

Well, suppose it is the year 2039, for some strange reason your
camera was set to unix epoch and you want to adjust the pictures
to current time.

Ok - that's a far-fetched scenario. The real reason is that this
hopefully silences a Coverity warning and avoids integer casting.

6ae2d36e38 core: move picture-related function from dive.c to picture.c
Move the two functions create_picture() and picture_check_valid_time()
from dive.c to picture.c.

This might be somewhat questionable, as these functions are not purely
picture related, but check the nearest selected dives, etc. However,
dive.c is so huge, that slimming it down can't hurt. Moreover,
getting the nearest selected dive is more divelist- than dive
functionality anyway.

434644b381 undo: make picture (media) deletion undoable
The code is rather complex. Firstly, we have different representations
of pictures throughout the code. Secondly, this tries to do add the
pictures in batches to the divepicture model and that is always rather
tricky.

ebdb3e3c30 media: create sort_picture_table function via macro
This needs a slight change to the macro, because here we sort by
value type. Yes, from a C-programming point of view this is horrible,
however a decent compiler should just inline everything and not
pass around value types.

db24f16686 core: add get_picture_idx() function
A function that gets the index of a picture in a picture table
given its filename. Since we are going to identify pictures by
their filename, we will need this function in the undo code.

Use the function in the remove_picture() function.

989d6a3f96 media: use table instead of linked list for media
For consistency with equipment, use our table macros for pictures.
Generally tables (arrays) are preferred over linked lists, because
they allow random access.

This is mostly copy & paste of the equipment code.

Sadly, our table macros are quite messy and need some revamping.
Therefore, the resulting code is likewise somewhat messy.

3f3869ff65 media: move picture function from dive.c to picture.c
Currently, move only those functions that do not access dive
structures.
