7e632173e0 Collect and convert git repo data to 'struct git_info'
We have this nasty habit of randomly passing down all the different
things that we use to look up the local and remote git repository, and
the information associated with it.

Start collecting the data into a 'struct git_info' instead, so that it
is easier to manage, and easier and more logical to just look up
different parts of the puzzle.

This is a fairly mechanical conversion, but has moved all the basic
information collection to the 'is_git_repository()' function.  That
function no longer actually opens the repository (so the 'dry_run'
argument is gone, and instead a successful 'is_git_repository()' is
followed by 'opn_git_repository()' if you actually want the old
non-dry_run semantics.

194fe28d50 cleanup: don't hardcode array length
Move the ARRAY_SIZE macro into a header file and use it to determine the
number of cloud servers that we need to check.

9620d11828 cloudstorage: update remote if cloud server changes
If we can't reach the cloud server in the URL (which might come from the
settings or be passed in by the user), we try the alternative server(s).
If we end up changing servers, we need to update the remote that we have
already parsed from the URL.

766f297bc4 cloudstorage: try alternative server if first connection fails
If we can't reach our preferred server, try using a different one.
The diff makes more sense when ignoring white space.

With this we check the connection to the cloud server much earlier and
in case of failure to connect try a different cloud_base_url.

7fa031b648 cloudstorage: try to pick between multiple cloud servers
The backend infrastructure will soon be able to support more than one
cloud server which automagically stay in sync with each other.

One critical requirement for that to work is that once a session was
started with one of the servers, the complete session happens with that
server - we must not switch from server to server while doing a git
transaction. To make sure that's the case, we aren't trying to use DNS
tricks to make this load balancing scheme work, but instead try to
determine at program start which server is the best one to use.

Right now this is super simplistic. Two servers, one in the US, one in
Europe. By default we use the European server (most of our users appear
to be in Europe), but if we can figure out that the client is actually
in the Americas, use the US server. We might improve that heuristic over
time, but as a first attempt it seems not entirely bogus.

The way this is implemented is a simple combination of two free
webservices that together appear to give us a very reliable estimate
which continent the user is located on.

api.ipify.org gives us our external IP address
ip-api.com gives us the continent that IP address is on

If any of this fails or takes too long to respond, we simply ignore it
since either server will work. One oddity is that if we decide to change
servers we only change the settings that are stored on disk, not the
runtime preferences. This goes back to the comment above that we have to
avoid changing servers in mid sync.

c5eb806adb cloudstorage: some cleanup of cloud url handling
We know the preference is never empty, so stop testing for this. But
don't maintain two different preferences with basically the same
content. Instead add the '/git' suffix where needed and keep this all in
one place.

Simplify the extraction of the branch name from the cloud URL.

Also a typo fix and a new comment.

9c744e401e Cloud storage: remove outdated certificate hack
The old server certificates where not recognized on some older platform,
so we hardcoded the hex digest of the valid certificate and ignored the
error.

Those certificates have been replaced last week, so there is no point to
this hack anymore - also, we should always show the SSL error, not just
in verbose mode.

5da09a21bb Cleanup: move error reporting function declarations to errorhelper.h
Move the declarations of the "report_error()" and "set_error_cb()"
functions and the "verbose" variable to errorhelper.h.
Thus, error-reporting translation units don't have to import the
big dive.h header file.

c4c8094e32 get rid of some foreach and Q_FOREACH constructs
See https://www.kdab.com/goodbye-q_foreach/

This is reduced to the places where the container is const or can be made const
without the need to always introduce an extra variable. Sadly qAsConst (Qt 5.7)
and std::as_const (C++17) are not available in all supported setups.

Also do some minor cleanups along the way.

36b9e5e31e Cleanup: fold core/helpers.h into core/qthelper.h
helpers.h included qthelper.h and all functions declared in helpers.h
were defined in qthelper.h. Therefore fold the former into the latter,
since the split seems completely arbitrary.

While doing so, change the return-type of get_dc_nichname from
"const QString" to "QString".

b2b51c833a QML UI: redesign the user notification
The old system of cloud access updates with fake percentages just wasn't
helpful. Even worse, it hid a lot important information from the user.
This should be more useful (but it will require that we localize the
messages sent from the git progress notifications and make them more
'user ready').

177e21076b Allow the user to give longer cloud timeout on the command line
When stuck in areas with really bad internet 5 seconds may not be enough,
but making the timeout longer in general seems the wrong way to go. So
keep the default 5 seconds but allow the user to override that with
subsurface --cloud-timeout=NN

7be962bfc2 Move subsurface-core to core and qt-mobile to mobile-widgets
Having subsurface-core as a directory name really messes with
autocomplete and is obviously redundant. Simmilarly, qt-mobile caused an
autocomplete conflict and also was inconsistent with the desktop-widget
name for the directory containing the "other" UI.

And while cleaning up the resulting change in the path name for include
files, I decided to clean up those even more to make them consistent
overall.

This could have been handled in more commits, but since this requires a
make clean before the build, it seemed more sensible to do it all in one.
