- change the way how dive logs are mapped to dive details in
do_uemis_import()
- dives deleted on the Uemis will not be downloaded anymore (added
function uemis_delete_dive_by_diveid)
- change the way the memory consumption was checked to acknowledge
very large files (trying to predic on how many more files fit into
the buffer by calculating an average consumbtion over each
divelogs block)
- minimal design change to support the above

But sadly the code then doesn't actually use that return value, so this is

This function is only used in the Uemis downloader, and it got broken when
we switched to using a separate table for the downloaded dives.

Having random uuids seemed like a good idea, but there are several
situations where they really cause problems. One is merging dive file
imports from V2 logfiles. Another is testing such imports.
Instead of making the uuid random we now hash the name and add the
timestamp of the first dive associated with this dive site to the hash
(first in this context is "first encountered" with no guarantee that it is
the chronologically first). This way V2 imports create deterministic uuids
but uuid conflicts are still extremely unlikely, even if the user has
multiple dive sites with the same name.

Most of these will likely have no big impact, but it's better not to just
ignore them as they could lead to crashes.

A complete batch of divelog and dive data takes about 20% of the available
space (depending on how long those dives are). This is a hack and I can
see this potentially going wrong, but the alternative is to be even more
conservative and that has its own set of problems as it causes us to need
more "unplug, wait, plug in again and restart" cycles.

This looks like a fairly big change but it mostly just moves a block of
code inside an earlier loop and adjust a few variables around it.
The completely broken and insane Uemis download protocol distributes data
across different "databases" on the dive computer. The "divelogs" are
downloaded in batches of 10 (most of the time), and with this change every
time one of those batches is downloaded we straight away get the matching
"dive" entries.
Hopefully this will avoid having the download abort (for lack of space)
before all components are loaded.

When we run out of space in the Uemis filesystem we return an error. The
user could reasonably unplug the SDA, insert it again and then retry to
continue the download (that's what we tell them to do). In that case we
need to make sure we start at the correct dive otherwise the same dives
keep getting downloaded over and over again.

When we first get an invalid dive info and then, once we decremented the
offset, get a valid one but for the wrong dive and then try to calculate
the correct offset, we need to keep the existing offset in mind.
What a horrid design. Thanks, UEMIS.

After receiving another report of the Uemis downloader failing I tried to
make it more robust when unexpected things happen. The data structures
returned by the SDA are rather convoluted and not all relationships are
fully understood.
This makes sure we don't try to parse invalid dive entries, we only read
dive entries if we actually got new divelog entries, we only read dive
sites if at least one was referenced and we use a much more patient (and
hopefully, much more robust) algorithm to figure out which dive entry
corresponds to the new divelog entries.
What a pain.

In most cases the existing code might have done the right thing, but some
of the hard to reproduce errors might actually stem from the fact that we
have intermittend fs errors. Maybe this addresses things?
