RBT (Remaining Bottom Time) is a value calculated on the fly by some air
integrated divecomputers, for example Uwatec devices. This value is an
estimation based in some heuristic around time function pressure
gradients. This way, RBT would be the time a diver can spend at actual
depth without running out of gas (taking account of ascent, deco, if
required, and rock bottom gas reserve, if set).
Older Uwatec devices just made the calculus and only stored alarm events
if this time value reached zero, but modern devices store the value each
sample, in minutes.
It seems that Suunto Eon Steel is storing RBT values too, in seconds.
Libdivecomputer has supported RBT for a while, but Subsurface just
printed it to stdout and dropped it.
This adds support for RBT value on subsurface sample structure and shows
it in the profile's info box, right under TTS(calc), if selected, where
these two values can be easily compared by humans.

When calculating maxima for a dive, we need to take data from all existing
dive computer structures plus potentially also a fake dive computer
structure that is just passed in in order to create a meaningful profile.
Commit 86c961614b ("Actually walk all dive computers, don't just claim
to do so") missed that second case and no longer took the fake_dc into
account, breaking the display of dives that don't have samples.

If the first dive computer had pressure samples, but the second one (and
no higher one) did, then we would draw a flat horizontal line for the tank
pressure graph (but lable it with the correct pressures). This routine
that is hunting for the actual maxima and minima does have to really go
through all dive computers, not just "this one and up".

This adds a toolbox icon to turn on a tissue plot inspired by the bar

It shows the inert gas partial pressures for individual compartments. If
they are below the ambient pressure (grey line) they are shown in units of
the ambient pressure, if they are above, the excess is shown as a
percentage of the allowed overpressure for plain Buehlmann. So it has the
same units as a gradient factor. Thus also the a gradient factor line (for
the current depth) is shown.
The different tissues get different colors, greener for the faster ones and bluer
for the slower ones.

This patch implements the cylinder pressure calculations for diluent
gas in CCR dive computers. This is the third patch for achieving this.
The following were performed:
1) Add two lines to try_to_fill_sample() in parse-xml so that
diluent cylinder pressures are stored from XML dive log file
into structures of sample.
2) Add one line to populate_plot_entries() in profile.c so that
the diluent cylinder pressures are copied from structures of
sample to structures of plot_info.
3) add three constant #defines in profile.h
4) change populate_pressure_information() in gaspressures.c in
order to take into account pressure calculations for the
diluent cylinder, calling subordinate functions in the
appropriate way.
5) change create_plot_info_new() in profile.c in order to initiate
the pressure calculations for the diluent cylinder.
6) Implement two debugging functions (one in profile.c, another
in gaspressures.c). These debugging functions are activated
by means of #defines.
Two function calls dealing with oxygen pressure are currently commented
out. They will be activated in the following patch that attends to CCR
oxygen partial pressure calculation.

This patch implements a separation of the code for gas pressure
calculations from the rest of the code in profile.c. The latter
file is now split into: profile.c and gaspressures.c. The
details of the transferred functions is given at the top of
gaspressures.c. The following chnages were made:
1) dive.h: The function types of calculate_depth_to_mbar
and depth_to_mbar were made non-static in order to make them
available within gaspressures.c.
2) profile.c: Prototypes for the functions in gaspressures.c
were inserted at the top of profile. Ten functions were
transferred from profile.c to gaspressures.c
3) gaspressures.c as well as a short header, gaspressures.h
were created.
For the gas pressure calculations for CCR dives, gaspressures.c
forms the immediate basis for further code development.

get_pr_interpolate_data and removed an unused variable from
get_pr_interpolate_data. No real change here, just trying to make the code

Interpolated lines for tank pressures were presenting discontinuities
(sudden drops) and stalls (horizontal lines) with certain dive profiles.
The main reason seems to be that the discrete interpolation of tank
pressure was adding small pressure increments that could be rounded down
or up repeatedly generating cumulative rounding errors that would mean
either a delay on pressure drop that would be drawn as a sudden drop or as
a premature pressure drop that would result in a flat line.
This patch changes the way the discrete interpolation is done, so that we
don't have cumulative rounding errors distorting tank pressure lines.
To calculate accumulated pressure_time values the get_pr_interpolate_data
function was created. The fact that get_pr_interpolate_data transverses
the beginning of the plot_info entry list for each entry that needs
interpolated tank pressure isn't optimal at all. There might be a way to
properly track the data necessary to interpolate tank pressures from
inside the main pi->entry loop in fill_missing_tank_pressures.
Unfortunately I didn't manage to do it inside fill_missing_tank_pressures
so we have get_pr_interpolate_data.
The SURFACE_THRESHOLD test from pressure_time function was also removed as
no matter how shallow the diver is, if he is using the cylinder to breathe
the cylinders tank pressure should be affected.
