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
so much. See issue #1.

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.

Fixes issue #169

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.

Movdqu is more expensive (throughput, uops) than movq.  Minimal

The patch related with issue #55 (5a72620d) fixed some warnings, but the
fix was not optimal. It actually was a trick to confuse compiler rather
than a fix.

This patch fixes it by creating a new macro used when needed just a high
limit check for an unsigned.

the previous commit laid the groundwork by doing two sets of idcts
together. this moved that further by grouping the interesting data
(q[0], q+16[0]) together to allow using wider instructions. also
managed to drop a few instructions by recognizing that the constant
for sinpi8sqrt2 could be downshifted all the time which avoided a
dowshift as well as workarounds for a function which only accepted
signed data

looks like a modest gain for performance: at qcif, went from ~180
fps to ~183

On each MB, loopfiltering is done right after MB decoding. This
combines two loops in multi-threaded code into one, which reduces
number of synchronizations to half.

The above-row/left-col data are saved in temp buffers for
next-row/next MB decoding.

Tests on 4-core gLucid machine showed 10% decoder performance
gain with threads=4 (tulip clip). Testing on other platforms
isn't done yet.

GET_GOT was producing a zero length call.  This resulted in
pipeline flushes occuring when returing from the assembly
functions.  Masked on out of order cores, but evident on
Atom cores.

There is no need to make sure that the lower byte of the
register is 0 because the downshift by 11 overwrites that byte.
