All decode_channel_map calls together can easily read
more data than the amount of padding available.
Thus below patch adds an input length check before reading them.
Fixes some invalid reads with sample from
http://bugzilla.mplayerhq.hu/show_bug.cgi?id=1138
This is required specifically for setting frame->format to -1,
otherwise it will be set to 0 = PIX_FMT_YUV420P and code reading
the format from the output decoded frame will get misled.
In particular fix regressions occurring with the pending vsrc_buffer
patch.
The format is a per-frame property, having it in AVFrame simplify the
operation of extraction of that information, since avoids the need to
access the codec/stream context.
width and height are per-frame properties, setting these values in
AVFrame simplify the operation of extraction of that information,
since avoids the need to check the codec/stream context.

This reverts commit f8bed30d8b. The reason
for this is that the overlap filter, which runs after IDCT, should run
on unclamped values, and thus IDCT and put_pixels() cannot be merged if
we want to attempt to be bitexact.
lowres option crashes with wmv2 files which I have for test,
so I think it's better to remove the support to the time when
lowres will be really supported by this codec

Do not use rlelen for buffer size in init_get_bits, it is
only the size of the data for the first field.
Since it is not reliable, just use the size of the whole buffer.
Additional comments add removal of unused rlelen variable by
Reimar Döffinger.
This means it uses full brightness range and brightness
increasing instead of decreasing with index of non-opaque
color.

ALPHA: Replace sized int_fast integer types with plain int/unsigned.
Duplicate DPX image encoder
Duplicate DPX decoder: read sample aspect ratio
Duplciate DPX decoder: add buffer size checks.

ac3enc: remove bandwidth reduction as fallback for bit allocation failure.
ac3enc: merge compute_exp_strategy_ch() into compute_exp_strategy()
ac3enc: return error if frame+exponent bits are too large instead of using av_assert2().
ac3enc: differentiate between current block and reference block in bit_alloc()
