This actually didn't make a difference for the common case, since our
simplified gas compressibility model had a compressibility factor of 1.0
up to 200 bar, and increased smoothly from there. As a result, the
common 2400 and 3000 psi workpressures didn't really see an effect from
this.
Not taking compressibility into account does kind of make sense for
cylinder naming, since the cylinder may be used for different gases with
very different compressibility characteristics.

This marks "surface_volume_multiplier()" static in preparation for
changing it to use an actual honest-to-goodness compressibility
estimation. Without that, it wasn't obvious that the function wasn't
used in other random places.
Also, remove the "wet_volume()" function. It was unused, but more
importantly, it was wrong. Yes, it was the inverse of "gas_volume()",
but when you calculate wet volumes from the imperial sizes, you don't
actually use the "real" gas volume, you use the idealized one.

The code was wrong (and in the case of metric display for weights >= 20kg,
spectacularly wrong) in more or less all cases.

Instead of re-calculating all the interpolation data for each plot entry
(which means that we have a quadratic algorithm that walks over all the
plot-info points for each plot-info point), we can just update it
incrementally within any particular interpolation segment.
The previous cleanups made the code sane enough to understand, and makes
it trivial to see how you don't have to recalculate the full thing.
This gets rid of the O(n**2) algorithm, and it instead becomes O(n*m)
where 'n' is the number of plot entries, and 'm' is the number of gas
segments (which is usually a much smaller numer, typically "1").

With the two bigger simplications, this just re-organizes the code to do
the "interpolate.pressure_time" update that is shared among all the
"after segment start" cases in just one place.
That leaves the get_pr_interpolate_data() much simpler, and makes it
much clearer what it actually does.
In particular, it becomes very obvious that "interpolate.pressure_time"
is constant for one particular segment (it's the total pressure time),
and that "interpolate.acc_pressure_time" is the one that gets updated
for every entry.
The next step is to only call this for the first entry, and then update
just the "acc_pressure_time" in the caller.

Getting rid of the pointless always-zero pressure now makes it obvious
how some of the remaining code can just be removed too: there is no
point in re-initializing the pressure_time entries to zero at the
segment start, because they started out zero and we just checked that we
don't do anything to them before we hit the segment start.
Similarly, now that the silly pressure testing is gone, it is obvious
that the code for "i < cur" and "i == curr" cases is identical, and the
two cases can just be collapsed.

In the function fill_missing_tank_pressures(), we only ever call
get_pr_interpolate_data() if "pressure" is zero. So passing it in as an
argument, and then testing whether it is zero or not, is just totally
pointless, and only obfuscates things.
This whole thing seems to be due to people editing the code over time,
with the tests becoming superfluous as the code around it changed, and
nobody looking at whether it actually made sense any more.

We (ab)use fake_dc() to create a pleasing profile for a manually added
dive. Based on it's intended use, fake_dc() simply handed back a dc
structure that pointed at staticly allocated samples - that's obviously
(now that I think about it) going to blow up in my face if I edit a
manually added dive more than once.
So now we have an option for fake_dc() to actually allocate the samples -
this way the rest of the code can treat these samples as we would treat
samples created any other way. We can free them and replace them with a
new set.

Once we identified that our filename is actually a git designator (as seen
by the fact that it ends in a [branchname] surrounded by '[]'), we
shouldn't try to open that filename in order to try other ways of parsing
the data; instead we should just return an error to the caller.
This way the calling code can tell that an error occured.

We used to mark CCR dives by having "SP change" event at time 0:00.
As we nowadays mark CCR dives by setting dc->divemode appropriately,
better to convert the old dives to this format as well. This way we do
not have to take the special old format into account on multiple places
in the source.

The way sectioning of the dive list works is by watching for different strings
in the section.property. In order to be able to tell different trips apart we
combine the address of the dive trip variable with the location (which will
create a new section for a new trip, even if the location text is the same) and
then strip that information out before showing the trip header.

start of the QSettinsg Object Wrapper usage on the code
this first patch removes two macros that generated around
200 lines in runtime for something like a quarter of it
Basically, whenever we changed anything we called the
PreferencesDialog::settingsChanged and connected everythign
to that signal, now each setting has it's own changed signal
and we can call it directly.
The best thing about this approach is that we don't trigger
repaints for things that are not directly profile related. (
actually we still do, but the plan is to remove them in due time)
this commit breaks correct atualization of the profile (because
everything was connected to PreferencesDialog::settingsChanged)
and now I need to hunt a bit for the correct connections

It appears that the Qt documentation might be incorrect. It claims that
the precision value is digits after the decimal point, but we have seen
examples where the values posted to the server appear to have a total of 6
digits, including the digits ahead of the decimal point.
Upping this to 9 shouldn't hurt if Qt gets fixed, but should work around
the issue reported by a tester.
