Parse the extension flag bit when reading the MPEG4 AudioSpecificConfig.

This has nothing to do with SBR/PS contradictory to what was noted when it was removed.

AVStream is no place for it and it's unused outside of ffmpeg anyway.

This is needed because not all players (e.g. MPlayer) are able to distinguish
two different Bink audio decoders when codec_tag is set.

As a positive side-effect, this gets rid of the following warning:
libavcodec/flashsv.c:190:38: warning: assignment discards ‘const’ qualifier from pointer target type

An official specification now exists and it is both more detailed and easier to
understand than the incomplete notes available here.  Also remove ideas on how
to implement an encoder; these notes are already present in the encoder.

This fixes the warning:
libavcodec/libopencore-amr.c:91: warning: missing braces around initializer

Some versions of the GNU assembler do not handle 64-bit
immediate operands containing arithmetic.  Writing the
value out in full works correctly.

This naming scheme is used elsewhere, so it's sensible to be consistent.

Lists of ':'-separated directories can be passed to -rpath-link directly.

This function is called with only 8-byte alignment from
imdct for size 16.  The fft4 function is not called for
the larger FFT or MDCT sizes, so this has no impact on
typical uses.

This tests sizes from 16 to 4096, not only the default 512.

Set the frame size when decoding DTS audio.

This has the side effect of fixing the computation of timestamps for DTS-HD in compute_pkt_fields.  Since frame_size is
not currently set, the duration of a frame is being guessed based on the streams bitrate.  But for DTS-HD, the bitrate
currently used is the rate of the DTS core which is much different than the whole DTS-HD stream and leads to a wildly
inaccurate frame duration estimate.

Change the test program to output text instead of binary files so
it can be compared easily in FATE.
