2020-03-07gst: utils: Add simple scoped lockers for GMutex and GRectMutexNicolas Dufresne
While GLib has locker implementation already using g_autoptr(), recursive mutex locker was only introduced in recent GLib. Implement a simple locker for GMutex and GRectMutex in order to allow making locking simpler and safer.

2020-03-07gst: Add utility to convert StreamFormats to GstCapsNicolas Dufresne
This transforms the basic information found in StreamFormats to GstCaps. This can be handy to reply to early caps query or inside a device provider. Note that we ignored generated range as they are harmful to caps negotiation. We also don't simplify the caps for readability reasons, so some of the discrete value may be included in a range.
