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.

Prior to this change, we had two different cylinder lists as models for
drop down boxes - one that prepends the "no default cylinder" entry
(which we need for setting up no default cylinder to be used in the
app), and another one that only includes actual cylinders.
The problem occured if a dive is created before the first time we edit
an existing dive: in this case we are applying indices across the two
models, but the indices are of course off by one; this results in
actually picking the wrong cylinder. So each time we try to edit a dive,
we end up with the previous cylinder in the list.
This commit simplifies the code by having only one place where we create
list of cylinder names (which is then used as the model for the combo
box). It also uses more logical names for the two 'flavors' of this list
to make it clear which one is supposed to be used (the regular list when
editing or adding dives, the one with the "no default cylinder" entry
prependet for the Settings page).

Since we save after every operation in the mobile app, this allows us to
tell the user what we actually saved - and we can remind the user that
they can undo/redo the last operation.
The code gets more complicated because in the case that the operation
that triggered this change was an undo, we need to show the redo text to
describe what we are saving, and must point the user to the redo
operation.

Since switching to the mobile-models and removing grantlee,
DiveObjectHelper was demoted to a thin wrapper around string
formatting functions. The last user was removed in a previous
commit.
It was never a good idea, given QML's strange memory-management.
Let's remove it.

When editing a dive, a DiveObjectHelper of the unmodified dive
was created to compare the edited with the old values. Since
the DiveObjectHelper is used here only as a pointless wrapper
around the formatting functions, call these functions directly.
However, note that the code is in principle wrong since the
change to the mobile-models, which do not use the DiveObjectHelper.
The real fix would be to reload the data from the model to prevent
going out-of-sync with respect to the formatting routines!

This allows the mobile UI to reflect the three states that the dive list can be
in:
- changes that haven't been written to local storage
- there potentially are changes in local storage that were not synced with the cloud
- dive list is in sync with cloud storage
The last state could be misleading if the user access the cloud from a
different device and makes changes to the cloud storage from there, but from
the point of view of this device, the states are consistent.

If we haven't connected at all to the cloud server we assume that there are
local changes. And whenever we save changes only locally, we also set that

If you pass in the repo name, it isn't treated as cloud storage, but simply as
local git storage and imported (i.e., added) to the current dive list.
This allows the user to work around failed no-cloud->cloud transitions, merge
different accounts, and most importantly deal with situations were conflicts on
the server caused us to move a cache out of the way and potentially make dives
that were on the mobile device inaccessible to the user.
Once a UI is added, this allows the user to recover those dives (realistically
this is not really all that potentially 'dangerous' to do, but it's definitely
something that would best be done after talking to someone who understands the
cloud storage and can guide the user...).

The strange enum casts (that apparently we needed in order to have strongly typed

Calling saveChangesLocal() seems like the right thing to do, but it
doesn't do anything useful if the dive list hasn't been marked as
changed. The correct helper function to call is changesNeedSaving()
which makes sure we save the changes and update all UI information.
[Berthold: since this removes the last QML caller of saveChangesLocal()
we can make that function private.]

Instead of the crude and error prone bool, let's just use the right tool

I'm suspicious that an issue that some people have seen around changes
not being saved is caused by our handling of alreadySaving.
When starting with Subsurface-mobile in no-autosync mode, we were able
to end in a scenario where alreadySaving was true, even though there
were no unsaved changes. And in that case no changes made during such a
session were saved unless the user forced a manual sync with the server.
This commit radically changes our approach to handling the flag. It
moves it right next to the actual calls into code that could modify git
storage, and ensures that the flag can never stay set.

The location information model is updated automatically by the

If the user tries to download from a device that he hasn't given the app
permission to read from, Android will pop up a dialogue asking for that

This way even if a USB device wasn't added through an Android intent, we
still have a way to scan for it and select it. This is especially
important in case a user has a cable that we haven't seen yet (i.e. with
a VID/PID that we haven't added to Subsurface-mobile), but that
nevertheless works with the android usb serial drivers.
This also makes the flow a little more logical / consistent when
deciding which connections to show.
