Replaced a rather cumbersome function that that did the above. Upon
the suggestion of Robert Helling who proposed a much shorter way,
this new function replaced the previous ones. This necessitated
changes to divelist.c, profile.c and plannernotes.c, as well as
dive.c/h.

This is a first step to interpret bailout events.
1) The event structures have a new attribute: divemode.
Currently interpreted dive modes are OC, CCR, PSCR.
2) When doing fill_pressures(), the calculation is aware
of divemode. When divemode is OC (==bailout), then
the appropriate calculations of gas pressures are done.
3) Two new functions get_next_divemodechange() and
get_divemode_at_time() are created to find divemode
changes in the events linked list and to determine
the dive mode at any point during the dive.
4) fill_pressures gets a small amendment to facilitate
the correct calculations, depending on divemode.
The cases where fill_pressures() is used *outside the planner*
are changed. The result is that, for dives with bailout, the
correct gas pressures are shown on the dive profile. The
deco for bailout dives is not yet correct. This is the
next step.

The planner notes were constructed using a sequence of
len += snprintf(buf, buflen - len, ...);
calls. This will fail once len > buflen, because the second parameter
of snprintf is unsigned. Note that snprintf returns the number of
bytes that would have been written if it weren't truncated.
Fix this by using membuffer with put_format()/put_string() and
asprintf_loc().
Fixes#1155.

Reduce the impact and visibility of icd calculations by writing
the data to the planner output only in cases where gas switches
involve:
1) ascent
2) helium is used as part of breathing gas
3) gas switch results in an increase in partial pressure of nitrogen.
Coding change:
1) The code for writing the header of the icd table as well as
the inclusion of the data in the planner output is made
conditional on the above three requirements. This involves
moving the code that writes the table header into the
function that writes an icd data item to buffer.
2) Manipulation of a boolean variable that controls writing
of the table header to buffer and that also determines
whether any icd results should be inluded in the planner
results.
3) Reorganise comments so that there are not multiple tabs between
the code and the start of a comment.

Move the above function from plannernotes.c to dive.c so that
it is available to be called from the dive log part of the
software, and not only from the planner. The following was done:
1) Edit the comment above the code to make it more accurate
2) Move the structure icd_data to dive.h
3) Create an external reference in dive.h for the above function
4) Copy the body of isobaric_counterdiffusion() to dive.c

This patch implements the calculation and printing of icd parameters
in the dive planner output. It does:
1) icd parameters are calculated following the rule-of-fifths for
OC trimix dives. For each gas change on the ascent that involves
helium, the change in gas composition as well as the change in
partial pressures are shown. If rule-of-fifths is exceeded, a
warning message is prinetd.
2) An independent function is provided that in principle enables
calculation of icd paramaters outside of the context of the
dive planner.
Further updates to icd calculations
These changes respond to #1047. Code style conventions have been
improved. The ICD table is now also printed when the planner is
set to verbatim mode. The code that created the html icd results
has been moved to a function. This does not make the code more
efficient (many parameters passed) but it makes the code more clean.

Internal floating point (FP) calculations should be performed using double
unless there is a very good reason. This avoids headaches with conversions.
Indeed, the vast majority of FP calculations were already done using double.
This patch adapts most remaining calculations. Not converted where things
that were based on binary representations and variables which weren't used
anyway.
An analysis of all instances follows:
core/plannernotes.c, l.404:
This was a comparison between two floats. On the left side, first an integer
was cast to float then multiplied with and integer and divided by a constant
double. The right hand side was an integer cast to a float. Simply divide by
1000.0 first to convert to double and continue with calculations. On the right
hand side, remove the cast, because the integer will be implicitely cast to
double for comparison. This conversion actually emits less instructions,
because no conversion to double and back is performed.
core/planner.c, l.613:
Same analysis as previous case.
subsurface-desktop-main.cpp, l.155:
A local variable representing the version OpenGL version. Turn this into
integer logic. Not only does this avoid dreaded FP rounding issues, it also
works correctly for minor version > 10 (not that such a thing is to be
expected anytime soon).
abstractpreferenceswidget.[h/cpp]:
A widget where the position is described as a float. Turn into double.
desktop-widgets/divelogexportdialog.cpp, l.313:
total_weight is described as float. Use double arithmetics instead. This
instance fixes a truncation warning emitted by gcc.
Calculating variations when in recreational mode doesn't make sense, and can
prevent variations from being calculated when switching back to Buhlmann or

When changing the date/time of a dive in the planner the dive may end
up in a totaly new position in respect to date/time of other dives in
dive list table. It can be moved to the past or the future before or after
other existing dives. It also could overlap with an existing dive.
This change enables identification of a new "virtual" dive list position
and based on this starts looking for previous dives.
Then it (as before the change) does init the deco calculation with any
applicable previous dive and surface interval.
If some of these applicable dives overlap it returns a neg. surface time
which is then used in the planner notes to prohibit display of results.
