04c5ab0e36 Uemis support: hack around the need to reconnect the Uemis Zurich
When the file system of the Zurich gets full, the only way to continue to
download from it, is to disconnect and reconnect the dive computer (which
resets the FAT file system that it emulates to 'empty').

This solution is rather hacky and weird because it does a hard count down in a
busy loop, but given the narrow use case, this may be acceptable.

This also adds support for the UEMIS_DIVE_OFFSET environment variable that
allows the user to skip dives on the device.

9c70261c0e cleanup: move declaration of utc_mk* functions to new subsurface-time.h header
No point in slurping in all of dive.h for translation units that only
want to do some time manipulation without ever touching a dive.

Don't call the header "time.h", because we don't want to end up in a
confusion with the system header of the same name.

94521c9958 Cleanup: remove bogus mark_divelist_changed() calls
The parsers / downloaders parse into a separate table and do
not directly change the divelist. Therefore, they shouldn't
call mark_divelist_changed().

Likewise split_dive_at() doesn't modify the dive list and
therefore shouldn't call this function.

Calling the function has the unwanted side-effect that undoing
the change will not clear the *-symbol in the title of the
main window.

Replace the fixed-size weightsystem table by a dynamically
relocated table. Reuse the table-macros used in other parts
of the code.

The table stores weightsystem entries, not pointers to
weightsystems. Thus, ownership of the description string is
taken when adding a weightsystem. An extra function adds
a cloned weightsystem at the end of the table.

Add a dive site table to each dive site to keep track of dives
that have been added to a dive site. Add two functions to add
dives to / remove dives from dive sites.

Since dive sites now contain a dive table, the order of includes

ff9506b21b Import: don't add to new trip while downloading
Since process_imported_dives() can add dives to a newly generated
trip, this need not be done in the downloading code. This makes
data flow distinctly simpler, as no trip table and no add-new-trip

Moreover, since now the trip creation is done at the import step
rather than the download step, the latest status of the "add to

26a4fb5632 Warnings: silence new gcc warnings in uemis-downloader.c
Since upgrading to gcc 8.2 it produces noisy warnings about
potentially truncated strings. It doesn't recognize that
filenr can never become >4000. So clamp it down explicitly.

Do this by adding a function that does the assembly of the
filename path. Adding unnecessary code to silence compiler warnings
is dubious, but in this case it might be reasonable.

Fix a second instance by increasing the stack-allocated buffer
to 32 bytes. Hopefully nobody has more divespots than would
fit in a 9-decimal digit number!

The downloadTable is passed in the device data structure, but

Instead, use the table from device data to avoid funny surprises
should we change to a non-global download table.

5a9faf2fea uemis: Fix mapping of object_ids to dive numbers
When performing a factory reset to an uemis, the object_ids within the divelog
will not be reset. Nevertheless, the dive numbers are reset to 1.
So, the first log will have a positive offset n to the first dive number.
The uemis-downloader used the object_id from the logs as a start point for
getDive, if dives were already synced before. This causes the sync to stall.
I prevent this by subtracting the lowest object_id from the requested before
using it as dive number.

d01b7bf891 Switch over to SSRF_CUSTOM_IO v2
I hate changing the IO interfaces this often, but when I converted the
custom serial interface to the more generic custom IO interface, I
intentionally left the legacy serial operations alone, because I didn't
want to change something I didn't care about.

But it turns out that leaving them with the old calling convention
caused extra problems when converting the bluetooth serial code to have
the BLE GATT packet fall-back, which requires mixing two kinds of
operations.

Also, the packet_open() routine was passed a copy of the 'dc_context_t',
which makes it possible to update the 'dc_custom_io_t' field on the fly
at open time.  That makes a lot of chaining operations much simpler,
since now you can chain the 'custom_io_t' at open time and then
libdivecomputer will automatically call the new routines instead of the
old ones.

That dc_context_t availability gets rid of all the

	if (device && device->ops)
		return device->ops->serial_xyz(..);

hackery inside the rfcomm routines - now we can just at open time do a simple

	dc_context_set_custom_io(context, &ble_serial_ops);

to switch things over to the BLE version of the serial code instead.

Finally, SSRF_CUSTOM_IO v2 added an opaque "dc_user_device_t" pointer
argument to the custom_io descriptor, which gets filled in as the
custom_io is registered with the download context.  Note that unlike
most opaque pointers, this one is opaque to *libdivecomputer*, and the
type is supposed to be supplied by the user.

We define the "dc_user_device_t" as our old "struct device_data_t",
making it "struct user_device_t" instead.  That means that the IO
routines now get passed the device info showing what device they are
supposed to download for.

That, in turn, means that now our BLE GATT open code can take the device
type it opens for into account if it wants to.  And it will want to,
since the rules for Shearwater are different from the rules for Suunto,
for example.

NOTE! Because of the interface change with libdivecomputer, this will
need a flag-day again where libdivecomputer and subsurface are updated
together. It may not be the last time, either.
