Description:
x264/libav's framework for x86 assembly. Contains a variety of macros and
defines that help automatically allow assembly to work cross-platform.
Local Modifications:
Get configuration from vpx_config.asm.
Prefix functions with vpx by default.
Manage name mangling (prefixing with '_') manually because 'PREFIX' does not
exist in libvpx.
Expand PIC default to macho64 and respect CONFIG_PIC from libvpx
Set 'private_extern' visibility for macho targets.
Copy PIC 'GLOBAL' macros from x86_abi_support.asm
Use .text instead of .rodata on macho to avoid broken tables in PIC mode.
Use .text with no alignment for aout
Only use 'hidden' visibility with Chromium

blocks above and to the left of the current block. The context index is
then the number (0,1,or 2) of these blocks having nonzero coefficients.
After decoding a coefficient, the measure is roughly the size of the
most recently decoded coefficient (0 for 0, 1 for 1, 2 for >1).
Note that the intuitive meaning of this measure changes as coefficients
are decoded, e.g., prior to the first token, a zero means that my neighbors
are empty while, after the first token, because of the use of end-of-block,
a zero means we just decoded a zero and hence guarantees that a non-zero
coefficient will appear later in this block. However, this shift
in meaning is perfectly OK because our context depends also on the
coefficient band (and since zigzag positions 0, 1, and 2 are in
distinct bands). */

* Notes:
*
* This implementation makes use of 16 bit fixed point verio of two multiply
* constants:
* 1. sqrt(2) * cos (pi/8)
* 2. sqrt(2) * sin (pi/8)
* Becuase the first constant is bigger than 1, to maintain the same 16 bit
* fixed point precision as the second one, we use a trick of
* x * a = x + x*(a-1)
* so
* x * sqrt(2) * cos (pi/8) = x + x * (sqrt(2) *cos(pi/8)-1).
