The unbuffered API will be made private and it's not used anywhere
internally.

They're unimplemented and nobody cared to do anything with that for
10 years.

full-bandwidth channels.

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

This restores the behaviour of running only the builtin
regression tests when no path to external samples is given.
aa3805a4 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.

The unbuffered URLContext API will be made private, so there's no point
in this function being public.

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.

Use it instead of url_is_streamed and AVIOContext.is_streamed.

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.

It's not used anywhere and apparrently hasn't been for a very long time.

It has been deprecated for about five years, skip_idct/skip_frame should
be used instead.

Fixes build with the bump, since the prototype is already marked for
removal.

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.

These expressions are equivalent since levels is always odd, and
overflow is impossible due to the constraints set by the assert().
