    gstdebug: fix occasional deadlocks on windows when outputting debug logging

    When outputting debug logs on Windows, some sections are protected
    with a non-recursive lock. Turns out though that gst_debug_message_get()
    might indirectly, via our printf format extensions, call code which
    in turn would try to log something when it can't handle something. If
    that happens we end up in gst_debug_log_default() again recursively and
    try to again take the lock that's already taken, thus deadlocking.

    Format the debug message string outside of the critical section
    instead to avoid this.
