8629fa3f18 core: bring back libgit2 certificate callback
Turns out that at least on Android libgit2 sometimes rejects valid
certificates. And I cannot quite figure out when and why. But since we
actually already checked the validity of the certificate when we called
canReachCloudServer() (and the Qt code handles certificates correctly),
we'll simply ignore this here and override the check to always return
true for our cloud server.

f9f4a9c232 debug output: ensure our debug output is captured on Android
I would have bet money that Android used to send stderr to the logcat
log, but apparently it doesn't (anymore?). So in order to be able to
have a chance to debug weird cloud storage issues on Android, let's do
some wholesale replacement of fprintf(stderr,...) with our own version
of the INFO macro that we long ago borrowed from libdivecomputer (and
rename it to ensure we don't have a conflict there).

2f8f6c4fa1 git-storage: add helper function to delete remote branch
This will be used by the test to clean up test branches that are created
on the server. Since we aren't testing that functionality (it's not
something that Subsurface itself ever does) the helper prints out errors
it encounters, but doesn't report them back to the caller.

f4ffd7a8fb git-storage: fix up old broken local caches to use the right branch
If you had one of the unfortunate local git caches with a local HEAD
just pointing to 'master', this will make note of that and then fix it
up to use the proper branch name in the cache repository.

[Dirk Hohndel: demoted from error to fprintf as most users won't care]

433149af19 git-storage: make creation of empty cache repo set the initial branch
In create_and_push_remote(), we set up the remote tracking etc to use
the proper branch name, but never actually set up the initial local
branch for the new cache repository at all.  So the repository would end
up with the default 'master' branch, instead of the branch name it
should have.

This went unnoticed, because most setups start by initializing the git
caches by cloning from the cloud, and that worked fine.

7594e7ca7f Unify username handling of remote git repositories
The username was extracted from https:// urls but not from ssh://
urls. Unify this by extracting the username from any remote url.
This is done with regard to unifying the file handling in the
frontend.

For this approach to work, the credential callback of the ssh://
transport had to be adapted. It now also supports username/password
in addition to private-key authentication.

Currently, the only way the user can use the username/password
authentication is by deleting a potential public key.

137e83f7f2 Fix file:// handling for git access.
Currently, in is_remote_git_repository(), git URLs of the form
"file://..." are recognized as local and the "file://" prefix is
removed. The shortened URL is then processed as if it was a remote
URL, which of course has to fail. So far so good - this is not
a remote repository after all. But the removal of the prefix is
not propagated to the calling is_git_repository() function and
handling as a local git repository therefore fails likewise.

To fix this issue, move removal of the "file://" prefix one level
up to the is_git_repository() function.

2878f32a22 Improve parsing of git error message
This is rather fragile code, and the capitalization of the error message
in libgit2 changed at some point. But commit 794739b4c0 ("strstr is a
case sensitive compare") didn't really fix the problem - as it broke
that same check for older libgit2 versions.

Instead use our new helper function to make it work with libgit2 old and
new.

Also, add some more error output so the next time we run into this it's
more obvious what broke and where.

e76f527fe5 Correctly create cloud account from mobile
The creation of a cloud account from mobile was broken. This fixes
it. Basically, we need to go online for a moment, and setup a correct
local and remote repo for the cloud storage.

Tested for the following scenarios: 1) inital account creation
including PIN handling from mobile, from a clean install .
2) open an already validated cloud account from a clean install.
3) open no-cloud style local account.
4) Switch between 2 already validated could accounts.
5) Try to create a cloud account without data connection.

Notice that scenario 4) does not work perfectly. A restart of
the app is needed to see the new logbook. So that is to be fixed.

Scenario 5) seems a non realistic corner case. This does not work
in a gracefull way. The user needs to remove the app, install it
again, and retry with data connection.

Further notice this is backgroud/core processing only. So no QML UI
changes as proposed (for example) bij Davide.

794739b4c0 strstr is a case sensitive compare
strstr is a case sensitive compare and the string reported from
libgit2 reads "reference" and not "Reference". Further investigation
reveals commit 909d5494368a0080 of libgit2. Here, the change is
made from Reference to reference, breaking our rather poor way
of detecting something from an error string. So, to be future-proof
to more libgit2 oddities, it might be wise to use strcasestr
in this situation. But this seems a not fully supported variant of
strstr, so leave it at this point.

777cbd9cfe Fix cloud storage authentication attempt counting
The authentication count was a static counter in the authentication
callback, which gets incremented until we consider the authentication to
have failed.

The problem with that is that it doesn't get incremented for just _one_
authentication operation, it gets incremented each time you try to load
or save, so eventually the code considers authentication to have failed
even if nothing ever went wrong.

This fixes it by making it static to the whole git-access file, and have
each operation clear it before starting a new remote access.
