Now that we agreed on not preserving framebuffers pinning is finally
allowed to fail because of signals. Use this to make pinning
and acquire the mutex in an interruptible way too.

Unpinning is still uninterruptible, because it happens as a cleanup
of old state, or undoing pins after one of the pins failed.

Oops, forgot to add this one to the series..
