4033625567 Fix a couple of possible divide-by-zero conditions in statistics
Several people reported the average time problem, but there's another
one lurking there too: if the dive duration is zero, you get bogus
average depth information too (but because that one was a floating point
divide, and by default they are unsignalling on x86, it didn't crash, it
just resulted in bogus results).

9fad1cb50f Fix broken average SAC calculation
old_sac_time was always 0 when calculating average air consumption.
Thus the results were incorrect.  Move the counter to stats_t structure
as suggested by Linus.

9933ccd7cf Show statistics of selected dives
If at least 2 dives are selected, show statistics of these dives on
Overall Stats. Otherwise, show the statistics of all dives. Temperature
is also added to the shown statistics.

Minor change to avoid adding statistics.h (moved the global variable and
external function declaration to display-gtk.h).
Another minor change to the text displayed for the "Stats" notebook page.

dfb94e5470 Add statistics for longest, shortest, and shallowest dive
I don't really like calling the shallowest dive "min depth", but all other
texts that I could come up with that were reasonably short weren't any
better...

68a1ff9cf5 Separate out single dive statistics and total statistics
Right now this just changes the infrastructure - nothing outside of
statistics.c is modified. This is simply in preparation to split out the
single dive info and the total dive statistics in the future (as we are
creating more info and more stats and they will overflow the screen area
available - so this will turn into two notebook tabs).

This commit does not change any functionality.

Having the O2 permille defined once is more readable.

9b1ea2ae6d Use common helper function for the "no cylinder info" case
Miika fixed the statistics code that didn't properly check for the "no
cylinder info" case - this cleans it up and just uses the helper
function in equipment.c.

Rename the helper to be slightly better named while at it.

O2 per cent from dive computer should be shown in Dive Info if one is
given even without pressure information for the cylinder.

66c04f4f47 Fix up the statistics page use of pressure data
The statistics page calculates air use separately, and also needs to be
fixed up for the split of the pressures into sample-vs-start/end.

97f09f3ea8 don't use strftime() due to locale issues
Make statistics.c use snprintf() with weekday(), monthname() instead of
strftime().  The mingw strftime() ends up having lots of problems at
least on Windows unless you set the locale just right, so just avoid the
problem by doing the simple function by hand.  We already did that in
other places anyway.

619ab9e828 Add Info & Stats page to the notebook
This provides the relevant information for the currently selected dive
plus a bunch of statistics over all dives in the dive_table.

The visual design has lots of room for improvement
- right now the different fields change size
- it might be nice to have a more modern look for the entries
- the O2/He field is odd - for most divers the He value will
  always be 0, so maybe we should only show He if there's at least one
  dive that uses He? Also, we simply do a comma separated list of gases
  for all the tanks used
