This was ultimately named OC_ARM_ASM_MEDIA instead.
It shouldn't have mattered in this case, as it shouldn't be possible to get
 OC_ARM_ASM_MEDIA without OC_ARM_ASM_EDSP, but clean it up anyway.

The SAD and SADT metrics have different ranges, so it is
necessary to use different scale factors when comparing
them.

Originally we used SAD, and when SATD was added, the
scale factor was updated without changing the name.
This commit finally does so. However, it is intended
that the code switch back to the SAD metric at higher
speed levels, we also keep OC_SAD_SHIFT with its
appropriate value, 6 according to Tim.

Likewise, OC_SAD_BINS is renamed OC_COMP_BINS in
expectation of supporting mode tables for both
metrics.

Don't change the block qii flags if no ac coefficients will be coded in the selected mode. The code previously tried to do this but failed, instead it desynchronized the qii costing with the coded flags. 0.065dB SSIM improvement on 312kbit/sec foreman_cif.y4m.

On non-glibc systems (Android), the system headers won't do it for us.
This also simplifies its use, since we can guarantee it's always #define'd
 (i.e., as 0 on non-gcc builds).

Signed/unsigned comparison and integer conversion overflow.

sse2trans.h was including encoder headers, when it can be used by the decoder
 alone.

svn path=/trunk/theora/; revision=17575

sse2idct.c was needlessly including x86enc.h when it is part of the decoder.
collect.c had a trailing space.

Remove a few unused variables (that were assigned to, but never used), and
 add an explicit cast to convert -OC_LOTS_OF_BITS to unsigned, since the C64x
 compiler complains about the sign change (arguably rightly so).

We don't actually use this for anything yet, but it may help calling
 applications (e.g., doing software YUV2RGB conversion).
Also, change ref_frame_data to point directly to the desired reference frame,
 rather than require a lookup through ref_frame_idx first.
This saves an indirection and gives a 0.7% speed-up at 720p on a Cortex A8.
It should have an even bigger benefit on C64x, though it wasn't benchmarked
 there.

mcenc.c: Skip the 4MV SATD in speed level 2.  2% speedup.  Avoid duplicating the first set b candidate (correctly adding the surrounding accelerators hurt efficiency).

This removes some useless clamping and only computes set B predictors when
 they're actually going to be used.

Coverity thinks we're overrunning this static array by passing it to memset.
In reality, it's a multidimensional array, and guaranteed to be contiguous, but
 we might as well silence this warning.

This should have had a _c suffix, which r17503 exposed.

This is needed to get OC_ARM_ASM, so the C bitpacking routines don't get used
 during header parsing.

The new code uses slightly less cache and fewer lookups.

Unfortunately, I didn't do this before actually making the release.

This avoids repeatedly performing the MB mode -> reference frame translation,
 which is done many times per fragment during DC prediction.
In fact, by using a special OC_FRAME_NONE tag for uncoded fragments, one need
 not even check to see if a fragment is coded during DC prediction, simplifying
 it even more.
This saves 2% on 720p decode on a Cortex A8.
