a53540346a flacparse: tell baseparse the duration in samples for better accuracy 
Tell GstBaseParse the duration in samples instead of time, so that
a duration query in DEFAULT format will return the correct number
of samples without rounding errors. Baseparse will convert this
into time itself when needed.

e0cadab5c2 flacparse: don't error out on invalid minimum_blocksize value in streaminfo header 
We don't use it, so may just as well accept an invalid value
of 0 here, which is likely inconsequential anyway.

7f4a61b56c mpegaudioparse: Post CBR bitrate as nominal bitrate 
Even if VBR headers are missing, we can't guarantee that a stream is in
fact a CBR stream, so it's safer to let baseparse calculate the average
bitrate rather than assume a CBR stream. However, in order to make
/some/ metadata available before the requisite number of frames have
been parsed, this posts the bitrate from the non-VBR headers as the
nominal bitrate.

572366e179 flacparse: Don't parse the complete FLAC frames but only look for valid frame headers 
Thanks to Felipe Contreras for the suggestion. This is partially
based on his patches and makes flacparse more than 3.5 times faster.

Looking for valid frame headers is unlikely to give false positives
because every frame header is at least 9 bytes long, contains a
14 bit sync code and a 8 bit checksum over the first 8 bytes.

Fixes bug #631200.
