This caches the git ID for the dive on load, and avoids building the
dive directory and hashing it on save as long as nothing has invalidated
the git ID cache.
That should make it much faster to write back data to the git
repository, since the dive tree structure and the divecomputer blobs in
particular are the bulk of it (due to all the sample data). It's not
actually the git operations that are all that expensive, it's literally
generating the big blob with all the snprintf() calls for the data.
The git save used to be a fairly expensive with large data sets,
especially noticeable on mobile with much weaker CPU's. This should
speed things up by at least a factor of two.

This is useful if you are in an area with slow or spotty network and if
you are fine with just saving to the phone. In order to sync to the cloud
you either have to manually sync via the menu or turn this back on and
hide the application.
The commit also removes the old refresh from the Manage dives menu as the
semantic of that was possibly destructive now that we no longer
immediately save changes to git - those could be thrown away by selecting
refresh before the app had a chance to save them.

There may be other paths where we potentially show the wrong status to
the user... but at least with this it times out eventually; there
shouldn't be any single operation that isn't broken down with progress
markers that takes more than 10 seconds, so keeping the notification
around for 30 seconds seems very conservative.

Much as this felt like the prudent thing to do, it makes the UI painful
to use. In bad network conditions, with a large dive log, on a phone,
the save operation can take more than a minute - which is just completely
ludicrous.
So instead we mark the dive list changed when we make changes and wait
for the app to not be in the foreground. Once the OS tells us that we are
hidden (on the desktop that generally means we don't have focus, on a
mobile device it usually does mean that the app is not on the screen), we
check if there are data to be saved and do so.
There is of course a major problem with this logic. If the user switches
away from Subsurface-mobile but comes back fairly quickly (just reacting
to a notification or briefly checking something, changing a song,
something... then the app may still be non-responsive for quite a while.
So we need to do something about the time it takes us to save the git
tree locally, and then figure out if we can move at least some of the
network traffic to another thread.
And we need to make sure the user immediately notices that the app is not
crashed but is actually saving their data. But that's for another commit.
tl;dr: CAREFUL, don't kill Subsurface-mobile before it had time to save
your data or your changes may be gone. In typical use that shouldn't be
an issue, but it is something that we need to tell the user about.

This allows fairly fine grained analysis on what part of loading from
and saving to git we are spending our time. Compute performance and
network speed play a significant role in how all this plays out.
The routine to check if we can reach the cloud server is modified to
send updates every second so we don't hang without any feedback for five
seconds when there is network but we can't reach the cloud server (not
an unlikely scenario in many dive locations with poor network quality)

When manually adding a dive and moving it in the dive list (by editing
it's start time) we could create a situation where the dive list
internally was correct, but the dive list model on screen showed an
incorrect dive list with the new dive in two different spots.

This code is very similar to the undo code in the desktop UI, but
untangling that from the desktop seemed massive overkill; we don't have
lists of dives to delete and undelete here - so this is actually much
simpler and easier to maintain (I hope).

We (ab)use fake_dc() to create a pleasing profile for a manually added
dive. Based on it's intended use, fake_dc() simply handed back a dc
structure that pointed at staticly allocated samples - that's obviously
(now that I think about it) going to blow up in my face if I edit a
manually added dive more than once.
So now we have an option for fake_dc() to actually allocate the samples -
this way the rest of the code can treat these samples as we would treat
samples created any other way. We can free them and replace them with a
new set.

We only need to deal with this if the dive changed. And in that case, if
we calculate a new fake DC, we need to clear out the meandepth as
otherwise the algorithm will try to match both max and mean depth. Since
the user potentially changed the max depth that could have very odd
consequences.

When the user explicitly sets the units when editing or adding dives, we
used to change the display preferences. This was changed for some but not
all fields in commit 6252d0cd3b ("While parsing weight and pressure we
should not change the users settings")
Now we do this consistently for all inputs.
Also, when editing the depth of a manually added dive, we now throw away
the samples (as those are certain to be inconsistent).

Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
There are several parts of the UI that will do better if they know if the
credentials that we have are incomplete (e.g., no password), invalid
(server rejected them), valid (server accepted them) or potentially valid
(we found a local cache for the email address, so that's likely correct,
but because we are offline we cannot (or have not yet) verify the
passord).
So far this is specific for the mobile UI - it might make sense to try and
use the same backend code and status tracking for desktop and mobile.
