This ensures the tools are rebuilt when necessary.  Specifically,
lavfi-showfiltfmts was sometimes not rebuilt causing spurious test
failures.

This allows the CPU detection to work with assemblers not supporting
the xgetbv mnemonic.  These include clang and some BSD versions.

All AVX code will be written for yasm, where the main assembler
is not involved.

Update libavformat/version.h and doc/APIChanges after renaming
init_put_byte() and ByteIOContext to ffio_init_context() (private)
and AVIOContext, (public), and deprecating the originals.
(cherry picked from commit d2bbf82e)

init_put_byte should never be used outside of lavf, since
sizeof(AVIOContext) isn't part of public ABI.

Advanced profile never uses "range reduction", so vc1_put_block() quite
literally just calls put_pixels_clamped() from vc1_decode_i_blocks_adv().
By inlining the function, we can prevent calling IDCT8x8 if
CODEC_FLAG_GRAY is set, and we don't have to scale the coeffs in the
[0,256] range, but can instead use put_signed_pixels_clamped().

With negative stride, the start of the edge_emu buffer should be pointing to

With positive stride, pointing to the end of the buffer was completely wrong.

Also remove qscale_table code; this didn't make sense anyways as VP3 doesn't

On some versions of gcc, these weren't always getting inlined due to hitting
the inline cap limit in some files.  This is generally bad, as most of these
functions are smaller inlined than not.
