dlna: add GetProtocolInfo action

Adds support for querying media formats supported
by a Media Renderer device. Profiles related to
H264/HEVC and MP3/AAC/AC-3 codecs are added.

We transcode to the default/mandatory DLNA audio and video profiles
for any non-supported formats since these are suppose
to be supported by every DLNA certified device.
