c3f5b81125 Merge remote branch 'qatar/master'
* qatar/master:
  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: clip large coefficient values and negative exponents rather than using av_assert2().
  ac3enc: do not store a bandwidth code for each channel.
  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()
  ac3enc: simplify exponent_init() by calculating exponent_group_tab[] based on exponent group sizes.
  ac3enc: simplify stereo rematrixing decision options
Include both URLs:  Update URL to fate samples

ad1862d64a ALPHA: Replace sized int_fast integer types with plain int/unsigned.
int/unsigned is the natural memory access type for CPUs, using sized types
for temporary variables, counters and similar just increases code size and
can possibly cause a slowdown.

0665199e43 Merge remote branch 'qatar/master'
* qatar/master:
  vorbisdec: Rename silly "class_" variable to plain "class".
  simple_idct_alpha: Drop some useless casts.
  Simplify av_log_missing_feature().
  ac3enc: remove check for mismatching channels and channel_layout
  If AVCodecContext.channels is 0 and AVCodecContext.channel_layout is non-zero, set channels based on channel_layout.
  If AVCodecContext.channel_layout and AVCodecContext.channels are both non-zero, check to make sure they do not contradict eachother.
  cosmetics: indentation
  Check AVCodec.supported_samplerates and AVCodec.channel_layouts in avcodec_open().
  aacdec: remove sf_scale and sf_offset.
  aacdec: use a scale of 2 in the LTP MDCT rather than doubling the coefficient table values from the spec.
  Define POW_SF2_ZERO in aac.h and use for ff_aac_pow2sf_tabp[] offsets instead of hardcoding 200 everywhere.
  Large intensity stereo and PNS indices are legal. Clip them instead of erroring out. A magnitude of 100 corresponds to 2^25 so the will most likely result in clipped output anyway.
  qpeg: use reget_buffer() in decode_frame()
  ultimotion: use reget_buffer() in ulti_decode_frame()
  smacker: remove unnecessary call to avctx->release_buffer in decode_frame()
  avparser: don't av_malloc(0).

8dbe585641 Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 decoder.
This patch lets e.g. dsputil_init chose dsp functions with respect to
the bit depth to decode. The naming scheme of bit depth dependent
functions is <base name>_<bit depth>[_<prefix>] (i.e. the old
clear_blocks_c is now named clear_blocks_8_c).

Note: Some of the functions for high bit depth is not dependent on the
bit depth, but only on the pixel size. This leaves some room for
optimizing binary size.

Preparatory patch for high bit depth h264 decoding support.

a788196e20 Remove --enable-gprof flag
gprof is far too intrusive to be of use as a profile for ffmpeg,
and it fails to build in many configurations.  Oprofile is a
better tool for profiling on Linux.

be449fca79 Convert asm keyword into __asm__.
Neither the asm() nor the __asm__() keyword is part of the C99
standard, but while GCC accepts the former in C89 syntax, it is not
accepted in C99 unless GNU extensions are turned on (with -fasm). The
latter form is accepted in any syntax as an extension (without
requiring further command-line options).

Sun Studio C99 compiler also does not accept asm() while accepting
__asm__(), albeit reporting warnings that it's not valid C99 syntax.

987903826b Globally rename the header inclusion guard names.
Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.'  to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".

ab35de18cb Don't include config.h from assembly, because the mplayer developers
decided it was a great idea to put some (bogus, of course) C function
prototypes there and it doesn't seem worth bothering working around
that since all we wanted is HAVE_GPROF.
