This adds helpers to deal with the conversion from StreamConfiguration
to caps and vice-versa. This is needed to implement caps negotiation.

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.

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.
