This reverts commit 0fd88d3988.

Theres no reason to drop support for this.

Give a more generic advice.

This isn't used in practice anywhere within libav at the moment,
but change it for consistency until it is removed.
URL_RDONLY/WRONLY were fixed in commit 5b81e29593 (after the
values that actually were used were changed at the major bump,
in commit cbea3ac8), but this flag was unintentionally left unfixed.

Using the double variant causes several pointless conversions between
double and int.
Worse, one of the conversions is in an inner loop together with a
function using MMX, resulting in undefined behaviour.

The sporadic threading errors during fate-rv30 were caused by calling
ff_thread_await_progress with mb row -1 as argument. That returns
immediately since progress is initialized to -1. Not yet computed
motion vectors from the reference could be used for the first
macroblocks.

30-50% faster than the C implementation, 0.5% overall speedup on
bourne.rmvb.

The "new seeking API" was never finished and nobody is working on it.

They are deprecated and will be purged on next major bump.

Consistent with ffmpeg and ffplay.

Fixes ticket #823.

This fixes dithering for rgb555le, it appears gcc had moved the
setup of the variables after the asm or something like that.

From the patch by Reimar Döffinger.

Call av_free_packets() at each demuxing loop iteration, not only when
decoding.

X-ColaCount: +10l

av_destruct_packet() always frees the packet data even when the demuxer
is going to re-use it, thus causing crashes when decoding audio
frames (as implemented in a pending patch).

av_free_packet() is used instead, as it allows each demuxer to set the
right packet data releasing mechanism through the pkt->destruct callback.

When decoding coefficients, detect whether the block is DC-only, and take
advantage of this knowledge to perform DC-only inverse transform.

This is achieved by:
- first, changing the 108x4 element modulo_three_table into a 108 element
  table (kind of base4), and accessing each value using mask and shifts.
- then, checking low bits for 0 (as they represent the presence of higher
  frequency coefficients)

Also provide x86 SIMD code for the DC-only inverse transform.

This is different than a normal get_bits() over read because
decode_audio_specific_config() creates its own GetBitContext.
