Right now this requires that
(a) the dive have only one divecomputer associated with it.
Trying to split a dive with multiple dive computers would be *much*
harder to do, since you'd have to try to line up the surface
interval between computers etc. So just don't do it after
downloading multiple dive computers for the same dive.
(b) there must be at least one minute between the sample that came up
to the surface and the sample that goes down again.
If you just peeked your head above the surface, don't try to split
things into two dives. Maybe we can relax this for freediving or
something.
also note that the split dive will only get new numbering if the dive
that was split was the very last dive in the divelist.

In some cases the rename of the cache directory would fail in my testing.
Based on code that Lubomir provided, this tries a Windows specific
implementation of folder rename if the QDir based one fails for some
reason - but obviously only if we are running on Windows.

This patch changes the dive merging to be much more careful about
things, because it turns out that we had several small oddities that
caused big merge issues.
The oddities are:
- the dive "duration" is actually how long we spend under water.
But that means that when we do "dive->when + dive.duration.seconds"
to calculate the end of the dive, that is nonsensical if you came up
to the surface in the middle of a dive.
Now, normally you don't see profiles like that, but once you start
merging dives together, it can go from "small detail" to "dominant
factor".
- We have two different cases of merging: the automatic "merge new dive
computer download if it looks like the same dive" (which always has a
merge offset of 0, since we merge it as a new dive computer) and the
"merge two different dives into one longer dive.
The code assumed that it could look at the "downloaded" flag for the
dive to check one or the other, but that doesn't really work.
Reading a dive from an XML file isn't any different from downloading
it.
So we need to change the logic to determine what kind of merge it is
to actually check the passed-in time offset.
With this, Stuart Vernon's test-case of eight dives with short surface
intervals in between end up merging correctly into one dive.

The logic to pick the initial dive ID for the uemis downloader was very
confused, and did not work at all when restarting a download when the
Uemis filled up, and the "Force download all dives" flag was set. It
also required a rather odd Uemis-specific callback from the download UI
because of how it picked the initial ID.
This changes the logic to just look at the list of downloaded dives when
restarting, which simplifies the logic a lot, gets rid of the odd
special callback, and also means that the whole "Force download" issue
just goes away. It seems to work now.

So far, add_segment() returned a tissue tolerance (i.e. ceiling)
computed just in its return statement. This tissue_tolerance
needed to be dragged around until it was needed or be dropped
if not needed at all.
As for VPM-B, this ceiling computation is a bit expensive, this patch
calls the computation function tissue_tolerance_calc() when the
value is actually needed and not before.
This changes the signature of some functions.

and not some time before and store the result in a global variable.
This stores only the bottom gradients and computes the Boyle compensation
when computing the allowed ambient pressure.
As the Boyle compensation needs a reference ambient pressure, to find the ceiling,
we have to iterate this computation until the reference pressure is close enough to
the ceiling.

otherwise VPM-B planned profiles seem to violate the ceiling. This needs
the first_stop_pressure to be available also in the profile, so I made
it global in planner.c
Important lesson: If you want to use deco_allowed_depth on a tissue_tolerance
that comes from a VPM-B planned dive, you have to call boyles_law() before
add_segment()!

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.

This sets up a standard dive scenario (30 minutes at 260ft/79m, EAN36 and
Oxygen as deco gases, last stop at 20ft/6m) and calls the planner to set
up a dive plan given certain standard gases.
Instead of trying to verify the complete plans it checks that we switch to
the deco gases at the right depth and the complete duration of the dive
matches our expectation.
The test intentionally fails right now for imperial as we have the wrong
switch depth for Oxygen. See how useful tests are?
On the downside, the test does NOT produce the same plan as Subsurface
when I try to create a consistent setup for both - and I have not been
able to figure out why. There must be some other parameters that I'm not
setting, but I haven't identified them, yet. It's very small differences,
for example in the metric case the stops at 21m, 9m, and 6m are each one
minute shorter in the test than it what Subsurface calculates.

It improves (increases) gradients for all the compartments,
so more free gas can be created in the divers body. Next gradients
will converge, so the volume won't exceed the safe limit, indicated

The longer I stared at the existing code the less it made sense.

Save and load a usually unused copy of the preferences with the units that
were active the last time the dive list was saved to git storage (this
isn't used in XML files); storing the unit preferences in the data file is
usually pointless (that's a setting of the software, not a property of the
data), but it's a great hint of what the user might expect to see when
creating a backend service that visualizes the dive list without
Subsurface running - so this is basically a functionality for the core
library that Subsurface itself doesn't use but that another consumer of
the library (like an HTML exporter) will need.

This change once again tests if the remote can be reached. Even with a
fairly big data file and a medium speed internet connection the remote

We may need more checks / different heuristics / warnings if the sync
didn't happen, etc. But for now this should allow more reasonable testing.

This adds a new divelist context menu entry which asks for a URL. The file

When we delete a cylinder the gas changes in that dive may have to be
adjusted. We didn't do this at all in the past. With this commit we should
be doing this right for a single dive that is being edited.
This does NOT handle multiple dives being edited at the same time (or more
specifically - if you have multiple dives selected and delete a cylinder,
the dives that had the same set of cylinders (other than the displayed
dive) will get that particular cylinder deleted, but won't have their gas
change events (and sensor data in the samples) adapted.
Possibly we should simply prohibit deleting cylinders when more than one
dive are selected.

main difference to the old one is that time stamps are no longer

Upon successfull reading an image file, this computes a SHA1 hash of the
image and saves it with the picture tag in the log file. When a file is
not successfully loaded (for example because the log was created on a

to local file names.
That dictionary (actually two for both directions), is loaded on startup
