Call the right function to get the level. Also add some more debug
logging.

def1cf7276 pbutils: Add MPEG-4 Video profile/level extraction
This adds code to translate the profile_and_level indication from the
MPEG-4 video (ISO/IEC 14496-2) headers to a string profile/level. The
mappings are taken from the spec and Wireshark's code, and might need to
be expanded on.

e4bd09f0ed pbutils: add H.264 profile/level extraction functions to codec utils
This adds code to parse the first few bytes of H.264 sequence parameter
set in order to extract the profile and level as const strings. This
code was originally in both qtdemux and matroskademux.

0cf81938a1 pbutils: add AAC profile detection to codec utils
This moves AAC profile detection to pbutils, and uses this in
typefindfunctions. This will also be used in qtdemux.

c77f88cac6 pbutils: add codec-specific utility functions for AAC
This allows us to add generic codec-specific functionality, like
extracting profile/level data from headers, without having to duplicate
code across demuxers and typefindfunctions.

As a starting point, this moves over AAC level extraction code from
typefindfunctions, so it can be reused in qtdemux, etc.
