57ad189129 changed configure option name to reduce confusion
Renamed configure option "enable-psnr" to "enable-internal-stats" to
better reflect the purpose of the option and eliminate the confusion
reported in http://code.google.com/p/webm/issues/detail?id=35

71ecb5d7d9 Full search SAD function optimization in SSE4.1
Use mpsadbw, and calculate 8 sad at once. Function list:
vp8_sad16x16x8_sse4
vp8_sad16x8x8_sse4
vp8_sad8x16x8_sse4
vp8_sad8x8x8_sse4
vp8_sad4x4x8_sse4

(test clip: tulip)
For best quality mode, this gave encoder a 5% performance boost.
For good quality mode with speed=1, this gave encoder a 3%
performance boost.

a0ae3682aa Fix half-pixel variance RTCD functions
This patch fixes the system dependent entries for the half-pixel
variance functions in both the RTCD and non-RTCD cases:

  - The generic C versions of these functions are now correct.
    Before all three cases called the hv code.

  - Wire up the ARM functions in RTCD mode

  - Created stubs for x86 to call the optimized subpixel functions
    with the correct parameters, rather than falling back to C
    code.

209d82ad72 Add half-pixel variance RTCD functions
NEON has optimized 16x16 half-pixel variance functions, but they
were not part of the RTCD framework. Add these functions to RTCD,
so that other platforms can make use of this optimization in the
future and special-case ARM code can be removed.

A number of functions were taking two variance functions as
parameters. These functions were changed to take a single
parameter, a pointer to a struct containing all the variance
functions for that block size. This provides additional flexibility
for calling additional variance functions (the half-pixel special
case, for example) and by initializing the table for all block sizes,
we don't have to construct this function pointer table for each
macroblock.

f4a8594492 Add const qualifiers to variance/SAD functions.
These functions should never change their input, and there's no
 reason not to declare that.
This allows them to be passed static const data.

94c52e4da8 cosmetics: trim trailing whitespace
When the license headers were updated, they accidentally contained
trailing whitespace, so unfortunately we have to touch all the files
again.
