This tries to make our fingerprinting code work better, by avoiding
using the "deviceid" field that has always been unreliable because we've
calculated it multiple different ways, and even for the same version of
subsurface, it ends up changing in the middle (ie we calculate one value
initially, then re-calculate it when we have a proper serial number
string).
So instead, the fingerprinting code will look up and save the
fingerprint file using purely "stable" information that is available
early during the download:
- the device model name (which is a string with vendor and product name
separated by a space)
- the DC_EVENT_DEVINFO 32-bit 'serial' number (which is not necessarily
a real serial number at all, but hopefully at least a unique number
for the particular product)
but because the model name is not necessarily a good filename (think
slashes and other possibly invalid characters), we hash that model name
and use the resulting hex number in the fingerprint file name.
This way the fingerprint file is unambiguous at load and save time, and
depends purely on libdivecomputer data.
But because we also need to verify that we have the actual _dive_
associated with that fingerprint, we also need to save the final
deviceid and diveid when saving the fingerprint file, so that when we
load it again we can look up the dive and verify that we have it before
we use the fingerprint data.
To do that, the fingerprint file itself contains not just the
fingerprint data from libdivecomputer, but the last 8 bytes of the file
are the (subsurface) deviceid and the diveid of the dive that is
associated with the fingerprint.

In one weird case (suunto), the code in libdivecomputer.c
generates a device node directly instead of going the usual
way (setting the data in the dc-structure of the imported
dive). It is unclear to me whether that has to be that way,
as it depends on the chronological order of callbacks to
event_cb() and dive_cb().
Therefore add a device_table pointer to device_data_t
so that the downloader can add the device to this table. This
only adds the pointer, but does not yet use it in the
downloading code.

The DiveImportedModel and DownloadThread used the same table
of dives and dive sites. This made it very hard to keep the
model consistent: Every modification of the download thread
would make the model inconsistent and could lead to memory
corruption owing to dangling pointers.
Therefore, keep a copy in the model. When updating the model,
use move-semantics, i.e. move the data and reset the tables
of the thread to zero elements.
Since the DiveImportedModel and the DownloadThread are very
tightly integrated, remove the accessor-functions of the
dive and dive-site tables. They fulfilled no purpose
whatsoever as they gave the same access-rights as a public
field.

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
had to be changed: "divesite.h" now includes "dive.h" and not
vice-versa. This caused some include churn.

As opposed to dive trips, dive sites were always directly added
to the global table, even on import. Instead, parse the divesites
into a distinct table and merge them on import.
Currently, this does not do any merging of dive sites, i.e. dive
sites are considered as either equal or different. Nevertheless,
merging of data should be rather easy to implement and simply
follow the code of the dive merging.

To extend the undo system to dive sites, the importers and downloaders
must not parse directly into the global dive site table. Instead,
pass a dive_site_table argument to parse into.
For now, always pass the global dive_site_table so that this commit

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
flag has to be passed down to the libdivecomputer glue code.
Moreover, since now the trip creation is done at the import step
rather than the download step, the latest status of the "add to
new trip" checkbox will be considered.

The old way of merging log-files was not well defined: Trips
were recognized as the same if and only if the first dives
started at the same instant. Later dives did not matter.
Change this to merge dives if they are overlapping.
Moreover, on parsing and download generate trips in a separate
trip-table.
This will be fundamental for undo of dive-import: Firstly, we
don't want to mix trips of imported and not-yet imported dives.
Secondly, by merging trip-wise, we can autogroup the dives
in the import-data to trips and merge these at once. This will
simplify the code to decide to which trip dives should be
autogrouped.

In the future we want to download trips into a distinct trip-table
instead of the global trip-table to allow for undo of import.
Therefore add a trip_table argument to DiveImportedModel::repopulate()
and a trip_table member to DiveImportedModel. To correctly set these,
add a DownloadThread::trips() function, which currently simply returns
the global trip table.
Finally, make "struct trip_table *" a Q_METATYPE, so that the corresponding
arguments can be passed from QML.

To make data flow more clear, unglobalize the downloadTable object.
Make it a subobject of DownloadThread. The difficult part was making
this compatible with QML, because somehow the pointer to the
download-table has to be passed to the DiveImportedModel. Desktop would
simply pass it to the constructor. But with objects generated in QML
this is not possible. Instead, pass the table in the repopulate()
function. This seems to make sense, but for this to work, we have to
declare pointer-to-dive-table as a Q_METATYPE. And this only works
if we use a typedef, because MOC removes the "struct" from "struct
dive_table". This leads to compilation errors, because dive_table is
the symbol-name of the global dive table! Sigh.

I don't actually do any of the libdivecomputer parsing yet, and only

Commit df156a56c0 replaced "virtual"
by "override" where appropriate. Unfortunately, this had the
unintended consequence of producing numerous clang warnings. If
clang finds a override-modified function in a class definition,
it warns for *all* overriden virtual functions without the override
modifier.
To solve this, go the easy route and remove all overrides. At least
it is consistent.
