Use a custom std::map comparator functor to do all comparisons
on contained QStrings using Qt::CaseInsensitive on macOS and Windows.

Issue #5257

* Update createcajaplugin.sh

* first apply branding, then create copies. Better.
Fixes https://github.com/owncloud/ownbrander/issues/753

* fix https://github.com/owncloud/ownbrander/issues/752 too.

Move csync to src/ and compile most of it at C++

Just use cmocka_run_group_tests like we already use in
some of those tests.

Go through the Logger to enable the csync-QDebug bridge.

This will allow us to unify data structures between csync and libsync.

Utility functions like csync_time and c_std are still compiled as C
since we won't need to be coupled with Qt in the short term.

Make this consistent with the rest of the client code.

Documentation improvement for #5969

This prevents it from being removed from the exclude list, which
would be an issue since the client itself creates this file in a way
that wouldn't match on machines with different installation paths.

By setting the icon in Desktop.ini of the root folder, this adds the icon
both when browsing the folder directly and to the sidebar shortcut.

To avoid overwriting any user setting that could exist in Desktop.ini,
only do this if the file doesn't exist. Editing .ini files on Windows
isn't trivial and isn't worth it given that this file won't exist most
of the time.

Fixes #2446

Not only in the account wizard.

Update client docs version string to 2.3.2

Need to update this to match the latest version.

Clean up the client docs removing old, outdated, content

In the process, use an iconset to generate the icns using iconutil.
Also add some missing icon resolutions according to the guidelines.

Issue #296

This makes changes as suggested by @michaelstingl in
https://github.com/owncloud/documentation/issues/3240.

The Job is a LsColJob, not a MkColJob!

Reproduce by entering a name with invalid character that cause an error 400
in the folder wizard's remote path line edit.

(Relates issue #5924)

The mac style has the concept of Layout Item Rectangle that bleeds
widgets margins into parent margins. This unfortunately doesn't work
when the parent layout doesn't have any margin, like we do when we
have the hierarchy:
 Vertical(normal margin)
   / Horizontal(no margin, uses parent layout spacing)
     /Widget

I guess Qt should propagate remaining uneaten margins to grand-parent
layouts and so on to have this work properly, but nobody seems to
have touched that code since Qt 4.4.
So just try to make the problem less worse by making sure that
all checkboxes we want to align are either in the same layout, or
in a loyout of their own.

Issue #5492

The maximumHeight would stay at the last animated value.

Issue #5492

Just to force the logic to re-ask the credenticals, in case we were
already asking them when singin off.

Allow upgrade path when the server removes support for oauth
Relates: https://github.com/owncloud/client/issues/5848#issuecomment-317353049

We also need to force the account to commit the config to the disk,
otherwise we may not register we are no longer using owncloud and we
risk sending the password as the token to the token refresh API call

Before commit d3b00532,
fetchFromKeychain was called everytime we detect that the creds are
invalid (in AccountState::slotInvalidCredentials)
But since that commit, AccountState was calling askFromUser directly,
breaking the refresh of the token.

So I made sure AccountState::slotInvalidCredentials still calls
refreshAccessToken.

Another change that was made was too be sure to clear the cookies
in HttpCredentials::invalidateToken even when we are only clearing the
access_token. That's because the session with a cookie may stay valid
longer than the access_token

This reverts commit efa7821d.

This reverts the revert, but also add a check that the server version
is bigger than 10.0

Issue #4788

We only want to know if they were touched within the last 15 seconds,
so change the data structure to use a QMultiMap, and sort them by
QElapsedTimer. This allows us to iterate over old entries ordered by
time and to stop once we find a recent entry.

This makes the look-up slower but in most cases the folder watcher
will report any change within milliseconds, and we start from the
most recent. What this really makes slower are actual user file
changes while a fast sync is underways which will need to iterate
over the whole map to find out the file isn't there.

This reduces the growth of the memory usage when downloading a large
amount of files.

Also use c_path_to_UNC directly instead of doing an extra
UTF-8->wchar conversion.

OpenSSL might no longer be needed to build the client, but we still need
it to run it.

That reverts part of commit 6e57b021 for
this file.

Fix #5858
Reported in https://central.owncloud.org/t/locally-built-client-error-creating-ssl-context/8264

Issues: #5897, https://github.com/owncloud/oauth2/issues/48

This was only for Qt <= 5.4, which we don't really support anymore.
And even then, the data corruption is happens very seldomly anyway.

Fix for issue number #5692 : 

Abort owncloudcmd if the capabilities call fails.

Qt would otherwise still try to do HTTP/2 connection even over "http://".
And that does not work with server that does not support it
