e05a3ac713 ac3enc: select bandwidth based on bit rate, sample rate, and number of 
full-bandwidth channels.

This reduces high-frequency artifacts and improves the quality of the lower
frequency audio at low bit rates.

906fd03070 fate: fix partial run when no samples path is specified 
This restores the behaviour of running only the builtin
regression tests when no path to external samples is given.
aa3805a inadvertently broke this by always setting SAMPLES
to something.  Using := makes the ifdef test work as expected
when the FATE_SAMPLES environment variable is empty.

724f6a0fa4 avio: make url_fdopen internal. 
The unbuffered URLContext API will be made private, so there's no point
in this function being public.

403ee835e7 avio: make url_open_dyn_packet_buf internal. 
It doesn't look fit to be a part of the public API.

Adding a temporary hack to ffserver to be able to use it, should be
cleaned up when somebody is up for it.

79997def65 ac3enc: use generic fixed-point mdct 
This makes the AC3 encoder use the shared fixed-point MDCT rather
than its own implementation.  The checksum changes are due to
different rounding in the MDCT.

ab11317c1f lavf: make compute_chapters_end less picky. 
In particular, now it assumes that
a) chapters are chronologically ordered
b) chapters have the same timebases
c) duration of the stream is known
and asserts if any of these is not met.

Make it properly deal with harsher conditions.

cb7e2c1ca8 flvdec: read index stored in the 'keyframes' tag. 
'keyframes' metatag is not part of the standard, it is just
convention to use such kind of metatag information for indexing.
Structure is following, it allows to have it inconsistent:
keyframes:
 times (array):
  time0 (num)
  time1 (num)
  time2 (num)
 filepositions (array)
  position0 (num)
  position1 (num)
