Moved the bounds computation on vertical MV component out
of the loop that processes MBs within a MB row.

Enabled the first-pass encode to output the
map of macroblock coding modes required by
the AltRef filter.

Modified AltRef temporal filter to adapt filter length based
on macroblock coding modes selected during first-pass
encode.

Also added sub-pixel motion compensation to the AltRef
filter.

this was excluding all .asm files when it should have just been .asm
files in the top level directory and .asm.s files lower down. also be
more restrictive on some other items, and run the whole thing through
sort to keep it organized

The existing code applied a 6-tap filter with 0's on either end.
We're already paying the branch penalty to avoid computing the two
 extra columns needed as input to this filter.
We might as well save time computing the filter as well.
This reduces the inner loop from 21 instructions to 16, the number
 of loads per iteration from 4 to 1, and the number of multiplies
 from 7 to 4.
The gain in overall decoding performance, however, is small (less
 than 1%).

This change also means we now valgrind clean on ARMv6, which is
 its real purpose.
The errors reported here were valgrind's fault (it does not detect
 that 0 times an uninitialized value is initialized), but Julian
 Seward says it would slow down valgrind considerably to make such
 checks.
Speeding up libvpx rather, even by a small amount, seems a much
 better idea if only to enable proper valgrind checking of the
 rest of the codec.

This function was accessing values below the stack pointer, which
 can be corrupted by signal delivery at any time.

previous implementation compared each set of values to limit and then
&'d them together, requiring a compare and & for each value.

this does the accumulation first, requiring only one compare

This patch avoids compiling some debugging code in onyx_if.c. The most
significant fix is to avoid generating code for vp8_write_yuv_frame,
which is never called. Some other code was removed by the dead code
elimination performed by the compiler, and this patch does it with the
preprocessor instead. There are advantages both ways.

reconintra_mt.c is only required for building the decoder right now.
It could definitely be used for the encoder in the future, but it
currently depends on decoder only data structures. (onyxd_int.h,
VP8D_COMP, etc). Move it from common/ to decoder/ until the
necessary changes to the common multithread code are complete.

This patch is needed to build with --disable-vp8-decoder.

Shared libs generally require PIC, so this saves a little typing at

Build with -O2 rather than -O3, to dissuade the compiler from inlining

Having these symbols be available as functions rather than data is
occasionally more convenient. Implemented this way rather than a
get-codec-by-id style to avoid creating a link-time dependency
between the encoder and the decoder.

The MV decoding changes in c5fb0eb8 introduced a bug where the
macroblock clamping state was reset for each partition, so if an
earlier partition needed clamping but a subsequent one didn't,
the MB wouldn't receive clamping. Instead, the state is only
set during splitmv decoding, never cleared.
