Gwenole Beauchesne b59a5572af encoder: h264: derive profile and level from active coding tools.
Automatically derive the minimum profile and level to be used for
encoding, based on the activated coding tools. The encoder will
be trying to generate a bitstream that has the best chances to be
decoded on most platforms by default.

Also change the default profile to "constrained-baseline" so that
to ensure maximum compatibility when the stream is decoded.
