331e7c4cb3 imdct36: mark SSE functions as using all 16 XMM registers. 
On x86-64, it indeed uses all 16 registers (and on x86-32, this gets
clipped to 8). Not marking it properly causes callers of this function
to fail randomly because of XMM register clobbering.

9a7dc618c5 libavcodec: Don't crash in avcodec_encode_audio if time_base isn't set 
Earlier, calling avcodec_encode_audio worked fine even if time_base
wasn't set. Now it crashes due to trying to scale the output pts to
the codec context time base. This affects e.g. VLC.

If no time_base is set for audio codecs, set it to the sample
rate.

subtitle encoders once support is implemented in the public functions.

e2ff436ef6 lavc: Relax API strictness in avcodec_decode_audio3 with a custom get_buffer() 
Do not fail audio decoding with avcodec_decode_audio3 if user has set a
custom get_buffer. Strictly speaking, this was never allowed by the API,
but it seems that some software packages did so anyways. In order to
unbreak applications (cf. http://bugs.debian.org/655890), this change
clarifies the API and overrides the custom get_buffer() with the defaults.

This change is inspired by a similar
commit (c3846e3eba) in FFmpeg.

57facb73ab libx264: Don't leave max_b_frames as -1 if the user didn't set it 
max_b_frames is initialized to -1 for libx264, to allow
distinguishing between an explicit user set 0 and a default not
touched 0 (see bb73cda2).

If max_b_frames is left as -1, this affects dts generation (where
expressions like max_b_frames != 0 are used), so make sure it is
left at the default 0 after the libx264 init function returns.

This avoids unnecessarily producing dts != pts when using
profile=baseline.

55b9ef18e4 cabac: split cabac.h into declarations and function definitions 
This fixes standalone compilation of some decoders with --disable-optimizations.
cabac.h defines some inline functions that use symbols from cabac.c.  Without
optimizations these inline functions are not eliminated and linking fails with
references to non-existing symbols.

Splitting the inline functions off into their own header and only #including
it in the places where the inline functions are used allows #including cabac.h
from anywhere without ill effects.

3faa303a47 rv34: DC-only inverse transform 
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.

-Werror=declaration-after-statement.  START_TIMER declares variables and thus

d209c27b09 vc1dec: fix invalid memory access for small video dimensions 
For small video dimensions, these calculations of the upper bound
for pixel access may have a negative result. Using an unsigned
comparison to bound a potentially negative value only works if
the greater operand is non-negative. Fixed by doing edge emulation
when the upper bound is probably negative, everywhere that this
pattern appears.

aacf6b3a2f rv34: fix invalid memory access for small video dimensions 
For small video dimensions calculations of the upper bound for pixel
access may result in negative value. Using an unsigned comparison
works only if the greater operand is non-negative. This is fixed by
doing edge emulation explicitly for such conditions.

98f24ecd6c rv34: joint coefficient decoding and dequantization 
Perform dequantization while decoding coefficients instead of performing it
on the entire coefficients buffer.

Since quantized coefficients are very sparse, this usually causes a small
speedup. Speedup of around 1% on Panda board compared to the removed here
neon code. Global speedup is probably around 3%.
