When we first store things to the remote there won't be a matching branch
for it. And even if for some silly reason the remote branch got lost -
what's the point of telling the user that there is no remote branch? What
are they supposed to do about it. Let's just fix the problem and move on.

Once we failed to load data from cloud storage (for example the first time

This change once again tests if the remote can be reached. Even with a
fairly big data file and a medium speed internet connection the remote
sync is fast enough to call it nearly instantaneous. Maybe a couple of
seconds.
We may need more checks / different heuristics / warnings if the sync
didn't happen, etc. But for now this should allow more reasonable testing.

libgit2 takes forever (a minute or so) to figure out that it can't connect

The settings are stored in the local cache repository - so without

At the time of this commit support for this feature has not landed in
upstream libgit2, yet (but there is a pull request). Yet supporting this
here doesn't appear to cause any issue with older versions of libgit2,
either, so the http proxy support will simply not work when enabled and a
version of libgit2 that's too old is used.

This seems to work better than moving the Globe up there.
It's not ideal (I really want to be able to show one big picture for the

This reverts commit ec8ba5f830.
Turns out that moving the globeGps widget to a different quadrant breaks

Again, note that this currently only happens when you initially open the repository.
So if you do
subsurface https://.../repo[myubranch]
it will start up by fetching the remote information, and updating the
local cache. If you then download new dives, and do a save-and-exit, it
will save to the local cache, but it doesn't do the fetch at this point,
so the remote is now begind.
The *next* time you start subsurface, and load that git branch again, it
will fetch the remote, and now notice that the local cache is ahead of
it (because you downloaded new dives and saved them locally), and *then*
it will try to update the remote with the new information.
This is obviously bogus, but we will need to decide exactly how we want
to sync with the remote repository. But now the core functionality is
there, it's just that we need some interface to say "sync now".
Especially in the face of spotty (or non-working) internet, you want a
GUI etc for this whole remote sync, rather than doing it unconditionally
and silently whenever you load the local cache initially.
With that caveat:

I'm going to try to update the remote if the local cache is more recent
when we fetch the data, which requires access to the remote over a wider
range of code. This re-organizes the code so that we can free the
remote later without having to have nasty error handling.
We avoid the whole "if an error happened, free the remote and return" by
creating helper functions and freeing the remote in the caller, so that
all paths end up freeing it naturally.
NOTE! We want to try to update the remote when we save the local cache
too, so this whole "update remote when opening it" is incomplete. But
(a) we do want to do it here as well
and
(b) this is the easiest place to create the initial "push to remote"
code without any new "sync with cloud" interfaces.

We used to fetch the remote information but not actually do anything
about it, except report when it wasn't up-to-date.
Now we actually update the local cached copy if the remote has changed.
The code does not try to actually merge things, so only fast-forward
updates are done, but that should be the normal case. We might
eventually do some simple merging on our own, but I suspect manual
merging may be the safer option.
We don't currently ever update the remote repository, and only inform
users that our local repository is ahead of the remote. Fixing that is
the next step.

Since we should have far fewer dive computers than dives this straight
forward algorithm shouldn't cause any performance issues.
