This allows us to unconditionally set the cglobal num_args
parameter to a bigger value, thus making writing yasm code
even easier than before.

Also define AV_BPRINT_SIZE_* macros before av_bprint_init() declaration,
and mention them in the av_bprint_init() doxy.

This fixes "make fate-eval" on MSVC builds. Without this, the test outputs
"-1.#NaN" instead of "nan" on MSVS 2010.

Simplifies pshufb masks that operate on words.

This silence bunch of useless warnings like:

libavformat/mpeg.c:393:37: warning: variable 'dvdaudio_substream_type' is uninitialized when used within its own initialization [-Wuninitialized]

Accept 1.1234567 as simply 1.123456 instead of rejecting it.
The rounding is towards 0, which is acceptable and much simpler.

This adds macros for accessing the EFLAGS register and uses
these instead of coding the entire check in inline asm.

Previously it was interpreted as number of bytes, while the
documentation stated that it was the number of 8 byte blocks.
This makes it behave similarly to the existing AES code.

This code is intended for errors in external libraries
when no corresponding error code can be found.
AVERROR_UNKNOWN is too vague for that and looks like AVERROR_BUG.

Some API require a buffer and return a specific error
if it is too small. This error code helps to map codes.
