It's not used anywhere and its return value looks broken.

It's only used in one place and does the same thing as
avio_alloc_context.

There are several places where a buffer is byte-swapped in 16-bit units.
This allows them to share code which can be optimised for various
architectures.

unless it stands for ffmpeg the program or is historic

also update the multiple inclusion guards in config.h|mak

update mailing list references and irc channels in configure

The two functions are identical, no point in duplicating code here.

This fixes invalid reads/writes with this sample:

If the function is not inlined, an immmediate cannot be used for the
shift parameter, so the %cl register must be used instead in that case.

This fixes compilation for x86-32 using gcc with --disable-optimizations.

The 1-arg imul instruction cannot take an immediate argument, only a register
or memory argument.

This fixes unexpected name collisions that were occurring with variables
declared within the macros.
It also fixes the fate-acodec-ac3_fixed regression test on x86-32.

Functions interrupted by url_interrupt_cb should not be restarted.
Therefore using AVERROR(EINTR) was wrong, as it did not allow to distinguish
when the underlying system call was interrupted and actually needed to be
restarted.

This fixes roundup issues 2657 and 2659 (ffplay not exiting for streamed
content).

This is different from AVERROR(EINTR) because calls that fail with EINTR
should usually be restarted.

This increases the accuracy of coefficients, leading to improved quality.
Rescaling of the coefficients to full 25-bit accuracy is done rather than
offsetting the exponent values. This requires coefficient scaling to be done
before determining the rematrixing strategy. Also, the rematrixing strategy
calculation must use 64-bit math to prevent overflow due to the higher
precision coefficients.

This permits playback in ffplay when libavfilter is enabled.

In the event of overflow, the JV_PADDING state will avio_skip over
any overflow bytes (using JVFrame.total_size).
