The Cochran CSV depth exports are indeed in tenths of feet, but the
decimal is always 0, 3, 5 or 8. Where the 3 and 8 are obviously 0.25
and 0.75 rounded up to one decimal place.
So Cochran does seem to be very much about imperial units, with depth
and cylinder pressure scaled by four (depth in quarter-foot increments,
pressume in 4-psi increments)

The code is pretty useless, the comments perhaps equally so. I'm trying
to figure out what the data pattern is for the cochran CAN files. There
definitely *is* a pattern, but it actually seems to be different for the
files of different people - and it's not obvious in any case.
There probably are multiple versions of the format, and there might be
things like "David has a high-pressure sensor, and Alex does not" going
on too.

David McNett sent me some example Cochran CAN file data, along with his
UDDF exports of same. I still have absolutely no idea how to decode the
CAN files (although the subsurface decrypting code seems to correctly
decrypt the data, and I see binary patters rather than just noise), but
at least I can make sure we parse the UDDF portion better.

It is really annoying to have to type the device name each time you need
to import a dive from your computer, if you are not using the default
device name. This will save the device name in the configuration file and

It's very annoying to have to do "make install" to test a new xslt file,
just because the default xslt path has the standard install path as the
first entry.
At the same time, we do want to default to just using the standard
install location first.
So to allow both testing, and having a nice sane default, just add
support for a SUBSURFACE_XSLT_PATH environment variable that overrides
the default one if it exists.
So then you can just do
SUBSURFACE_XSLT_PATH=xslt ./subsurface
to run subsurface from inside the git tree itself, using the current
files in the git xslt subdirectory.

Looking at the XML of the two dives Szymon Kosecki sent out to the
subsurface list, I notice that our cylinder size conversion was wrong.
It looks like CYLINDERUNITS is what determines whether the cylinder size
is in metric (0) or imperial (1) units.
Of course, if you gave a cylinder size in cuft and didn't give a working
pressure, subsurface will just ignore the size as the random crap it is.
We *could* default to a working pressure of 3000 psi, of course.
This also picks up the CYLINDERDESCRIPTION value, although neither of
Szymon's dives actually had any description.
I need more SDE xml files to figure out how multi-cylinder dives look
etc, but I think this gets most *simple* SDE files converted almost
correctly now.

I'm hoping most other dive computers are quicker to import from than the
Suunto I have, but mine can take minutes to import all the dives. Sure,
we have that nice progress bar, so it shows that it's doing something,
but it's not really showing *what* it is doing.
So instead of showing just "Parsing dive X", let's show the date of the
dive. That way, when it takes two minutes to import all the dives, at
least you can see "oh, it's going back to the dives of last year" and it
then feels like you have some good reason for the delay.

Instead of using printf() to print the string updates ("Parsing sample

This partially fixes the second todo entry from commit b0ba22a068
("Show dive import error messages in the import dialog") and generally
makes for a more helpful import - at least for the largely error-free
cases.
Sadly, the messages that really come from within libdivecomputer itself
(like "suunto_vyper2.c:193: Failed to receive the answer.") when things
go really wrong are not caught. libdivecomputer does have a notion of a
logfile (set with "message_set_logfile()"), but that ends up being
really inconvenient.

On Linux and MacOS the subsurface_close_conf() doesn't really close the
config file (it flushes writes on MacOS), but on Windows it does
actually close the registry hkey.
Which is bad, if you change the settings multiple times - we assume that
the config file is open the whole time.
So add a "subsurface_flush_conf()" function, and call *that* when
changing configuration parameters. And call the close function only at
the very end.
Alternatively, maybe we should just open the config file separately
every time. I don't much care, maybe somebody else does.

libdivecomputer has the absolute worst interfaces to any library *ever*,
and randomly changes those crappy interfaces when it adds support for
new dive computers.
It would have been much better if the interface was just a "open this
device" with a device descriptor structure pointer, so that when Jef
adds support for new devices, the old descriptors still stay around and
work the same way - there's just a new descriptor structure that you
*can* use if you want. Along with a data structure to name the devices
and their descriptors, this would actually mean that users could just
support pretty much any random device that LD supports.
But no, that's not how libdivecomputer works. It has random enums and
crazy different ad-hoc interfaces for different dive computers. Or,
like in this case, crazy different ad-hoc interfaces for the *same*old*
dive computer.
Right now, for example, the support for the new Heinrichs Weikamp "Frog"
computer added a flag to the interface for the old OSTC_2 support.
Breaking any libdivecomputer users even if you didn't need Frog support.
And is there a version number in the header files to check for? Yes,
there's a version number. But no, it's not useful, since it doesn't
actually change with the interface changes. This time, Jef actually did
change the version number (from 0.1.0 to 0.2.0) as part of new
development version, but there's no reason to believe that it will
change in the future as the interfaces change - it never has before.
So it's actually safer - and easier to understand - to check for the
existence of the new header file inclusion mechanism. A new version of
libdivecomputer that supports the HW Frog computer will include the
"ostc_frog.h" header file when you include the libdivecomputer device.h
file, and that will result in HW_FROG_H being defined.
So we can check whether libdivecomputer has the new interface and
supports the Frog by doing an "#ifdef HW_FROG_H" hack. Ugh.

... but only do it if the numbering of subsequent dives was consecutive
to begin with.
Note that we do accept unnumbered dives (and will stop the sequence
check if we find one), but in order to renumber dives on delete, we
require that starting with the dive we delete, the subsequent numbered
dives have to be a nice incrementing series. If that is the case, then
we fix up that numbering as we delete the dive.
Put another way: if the dive numbering was an incrementing sequence
before the delete, then it will be a sane incrementing sequence after it
too. But if you had missing dives before the delete, we will turn the
delete into just another missing dive.
The basic rule is that we never renumber any dives unless that
renumbering is "obviously correct". It's better to leave old numbers
as-is (and expect that the user is going to do an explicit re-numbering
operation) than it is to change dive numbers in a sequence that we don't
understand.
I do suspect that we should possibly check the dive number "backwards"
too, but this doesn't do that.

This interface works the same way the "edit dive" menu item does: it's a
text entry meny item on the dive text entries (ie buddy/divemaster/notes
sections). Except you pick the "Delete" entry rather than the "Edit"
entry.
It kind of works, but it really is a pretty horrible interface. I'll
need to add a top-level dive menu entry for just deleting all selected
dives instead. And it would be good to be able to get a drop-down menu
from the divelist instead of having to do it from the dive text entries,
which is just insane.
But that requires gtk work. I'm not quite ready to get back into that.
Thus the "exact same insane interface as the explicit 'Edit' mode".

Pull weight management from Dirk Hohndel:

It turns out the odd "different CAN files have different header offsets"
came from the fact that the decode block was different lengths, and I
had not picked the correct place to start - and instead had found two
different places that were at different offsets due to the decode block
length differences.
This fixes that up, and it looks like the dive header is correctly
descrambled (but what the data *means* is unclear, although there is now
an ASCII date and time visible, so at least one part of it is pretty
obvious).
The actual dive data unscrambling is still different for the two
test-files I have to play with, I do not know why.

This descrambles at least parts of the header data. Some of it has the
same pattern of data 4kB apart, it may be that there is a dive hiding in
there too (ie what I currently call a "header" may in fact be a header
_plus_ a dive).
But the 4kB thing may well be an artifact of the crazy scrambling code
itself. Who knows what kind of chunking the Cochran Analyst
"encryption" uses.
As with the dive data, there seems to be some offset differences between
different CAN files.

So this descrambles all the dives in *one* of my cochran test files. I
still don't know what the dive data *means*, but it's not a random
jumble of bytes any more: there are very clear patterns.
However, the magic offsets that work for that particular CAN file are
not generic, because they don't work for another. So there is some
magic dynamic decoding that I don't know about. There is probably more
decode information in the initial decode block, over and beyond just the
scrambling bytes.
(The scrambling array is 234 bytes starting at 0x40001, but the first
actual *dive* data starts at 0x45e03, so there's tons of unknown stuff
in the file even outside the dives themselves)

Most of the parsers will want the content in memory, so keep them
simple. The fact that the Suunto parser uses "libzip" that has to
re-open the file is annoying and causes us to re-open the file etc.
But it's the odd man out, so don't design the "open_by_filename()"
function around it. Pretty much everybody else will want to avoid
having to cook up their own IO routines.
Also, when reading the file, NUL-terminate the buffer. This allows us
to just treat text files as large strings if we want to, and doesn't
