This just re-organizes the dive merging code so that we expose a new
"merge_dives(a, b, offset)" function that merges two dives together into
one with the samples (and events) of 'b' at the specified offset after
'a'.
We'll want to use this if a dive computer has decided that the dive
ended (due to a pause at the surface), but we really want to just turn
the two computer dives into one long one with an extended surface swim.
No functional changes, but some independent cleanups due to the trip
simplifications.

We don't change any of the samples, we just don't plot (or consider for
dive time / mean calculations) the samples at the beginning or end of the
dive that are less than a certain threshold under water. Right now that's
an arbitrary 75cm which seems to Do The Right Thing(tm) for the dives I
tried this with - but I'm happy to look at other values if this causes
problems for people with dive computers I do not have access to.

Add the bookmark and heading events to the list of events not to be
simplified just because they are redundant - in both cases they are
about the user doing something explicit (like the gaschange), so even
if the data is otherwise identical, they should likely be saved.
That said, both events are kind of pointless (we don't actually seem
to save the heading value for the heading events, and bookmarks are
universally just due to user error in at least my case). But still..
This overly aggressive filtering was introduced in commit 6ad73a8f04

This adds a couple of helper functions to manage dive trips
("add_dive_to_trip()" and "remove_dive_from_trip()") and makes those
functions do the trip statistics maintenance (trip beginning times,
number of dives, etc).
This was needed because the dive merge cases for multiple dive
computers showed some rather nasty special cases: especially if the
new dive information has been loaded into an XML file with trips
auto-generated, merging several of these kinds of xml files with
multiple dives in several overlapping trips would completely confuse
our previous code.
In particular, auto-generated trips that had the exact same date as
previous trips (because they were generated from the same dive
computer) really confused the code that used the trip timestamp to
manage the trips.
Adding the helper functions allows us to get the general case right
without having to have each piece of code that handles trip
information having to bother about all the odd rules. It will
eventually also allow us to make the dive trip data structures more
logical: right now the dive trip list is largely designed around the
odd gtk model handling, rather than some more higher-level conceptual
relationship with the actual dives.
But for now, this keeps all the data structures unchanged, and just
modifies them using the new helper functions.

The default filename handling is broken in two different ways:
(a) if we start subsurface with a non-existing file, we warn about
the inability to read that file, and then we exit without setting the
default filename.
This is broken because it means that if the user (perhaps by mistake,
by pressing ^S) now saves the file, he will overwrite the default
filename, even though that was *not* the file we read, and *not* the
file that subsurface was started with.
So just set the default filename even for a failed file open.
The exact same logic is true of a failed parse of an XML file that we
successfully opened. We do *not* want to leave the old default
filename in place just because the XML parsing failed, and possibly
then overwriting some file that was never involved with that failure
in the first place. So just get rid of all the logic to push the
filename saving into the XML parsing layer, it has zero relevance at
that point.
(b) if we do replace the default filename with a NULL file, we need
to set that even if we cannot do a strdup() on the NULL.
This fixes both errors.

When we fill the cylinder information in an imperial unit world, a
working pressure of zero is a special case, and forces us to use the
actual physical size of the cylinder in liter, despite the fact that
we normally would use cuft.
However, we compare that value against zero in a 'double', and in
between going through the gtk spinbutton logic, the zero we have
filled in then gets read out as some very tiny epsilon value from the
gtk spinbuttons (typically in the 10**-317 range). This causes us to
think that the zero isn't actually a zero, because gtk has done odd
things with it.
Fix this by calculating the millibar value (as an integer) first, and
check that *integer* against zero. Any crazy epsilon values will have
been rounded away, and our logic works again.
There's a good reason why subsurface does everything using integers
(ie the afore-mentioned "convert to integer millibar" etc) and doesn't
use floating point for any core data structures, only for conversion.
FP rounding and inexact behavior can be really subtle.

When we merge dives where the samples have come from different dive
computers, the samples may be offset from each other due to the dive
computers not having decided that the dive starts at quite the same
time.
For example, some dive computers may take a while to wake up when
submerged, or there may be differences in exactly when the dive
computer decides that a dive has started. Different computers tend to
have different depths that they consider the start of a real dive.
So when we merge two dives, look for differences in the sample data,
and search for the sample time offset that minimizes the differences
(logic: minimize the sum-of-square of the depth differences over a
two-minute window at the start of the dive).
This still doesn't really result in perfect merges, since different
computers will give slightly different values anyway, but it improves
the dive merging noticeably. To the point that this seems to have
found a bug in our Uemis data import (it looks like the Uemis importer
does an incorrect saltwater pressure conversion, and the data is
actually in centimeter, not in pressure).
So there is room for improvement, but this is at least a reasonable
approximation and starting point.

We now throw away redundant events, just as we throw away other redundant
data coming from the dive computer. Events are considered redundant if
they are less than 61 seconds apart and identical.
This also improves the display of the remaining events in the profile as
we now show the value of the event, if it is present (for example for a
deco event we show the duration of the deepest stop).
Finally, for events that define a range (so they set the beginning flag
and assume and end flag some time later) we no loger show the triangle but
assume that some other code handles visualizing them (as happens for the
ceiling events).

We used to have very spotty logic for picking the dive trip when
merging two dives. It turns out that that spotty logic almost never
really matters, because in practice you'll never hit the situation of
merging two dives with different dive trips, but it *can* happen.
In particular, it happens when you use multiple dive computers, and
end up loading the dives from one computer on top of the dives of your
other computer. If the clocks of the dive computers was set
sufficiently close to each other, the dive merging logic will kick in
and you may now have slightly different times for the dives that get
merged, and the trip merging logic got *really* confused.
The trip management also depends on the trip dates being updated
correctly when the dives associated with a trip are updated (whether
added or removed), and the trip merging code did none of that.
This fixes it all up. Hopefully correctly.

I just tried downloading some duplicate dives I had on my second dive
computer, and it all "just worked" and subsurface merged them for me.
Almost perfectly.
I say "almost", because in merging them, it threw my old weightsystem
data away, due to that not being merged.
Also, it was a perfect merge only because the computers are so similar
that they just line everything up - same water activation logic, same
sample interval, same pretty much everything. So while I know the
sample merging is not really the right thing to do (it was designed to
get the "merge the exact same dive from the same computer" case
right), it worked well enough for this particular case. I'll look at

Turns out we had a data field for visibility as a length unit - but never
used it. I can never guess how much visibility we actually had on a dive -
but I think most everyone can assign a rating between abysmal (zero stars,
"I couldn't read my dive computer even right in front of my mask" - trust
me, I had some of those dives) to amazing ("five stars, I could see farther
than I though possible" - and I had one or two of those, too). So I
changed this to an integer and am re-using the star infrastructure we have
for the overall dive rating.
When displaying this I was dismayed that we are running out of space in
the "Dive Notes" notbook. So I moved this to the "Dive Info" notebook.
This is not consistent and not logical. I think we need to revisit the
