Global Dependency and Release Freeze

[Ben Cooksley]

Hi all,

We've now finished catching up on everything and getting the CI system
settled down again so we're now able to lift the freeze.
I'll start sorting out the releases which have been requested shortly.

There is still some lingering breakage impacting Akonadi and KIO
however those can be fixed in isolation and do not affect other
builds.

The only significant breakage remaining is a crash within
update-mime-database which means tests reliant on XDG mimetypes may
fail or behave unusually on Windows.
Compilation is not affected by this.

Cheers,
Ben
