Map EAGAIN and EINTR from ff_neterrno to the normal AVERROR()
error codes. Provide fallback definitions of other errno.h network
errors, mapping them to the corresponding winsock errors.
This eases catching these error codes in common code, without having
to distinguish between FF_NETERRNO(EAGAIN) and AVERROR(EAGAIN).
This fixes roundup issue 2614, unbreaking blocking network IO on
windows.

Also change the comments a bit since the FOURCCs aren't specific to Flip4Mac
and different ones are used for 720 versus 1080 lines.

This adds the AAC codec to the list of audio codecs that results
in a PES stream_id of 0xc0 (audio stream).

GCC 4.3 and later are more particular about signedness matching
in vector operations. The operations under if(rangered) were
missing assignments and thus had no effect.

In the name of consistency:
put_byte -> avio_w8
put_<type> -> avio_w<type>
put_buffer -> avio_write
put_nbyte will be made private
put_tag will be merged with avio_put_str

In the name of consistency:
get_byte -> avio_r8
get_<type> -> avio_r<type>
get_buffer -> avio_read
get_partial_buffer will be made private later
get_strz is left out becase I want to change it later to return
something useful.

Advantage is that it allows us to combine several loops into a single
one, and these can eventually be merged into the IDCT itself. Also, it
allows us to remove vc1_put_block(), and makes CODEC_FLAG_GRAY faster.
Add drawutils.h and drawutils.c, and use them in the pad filter.
The new functions are going to be shared by other filters.

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.
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().
Allows playback of nonprimary audio streams in multiple bitrate sources,
such as mmsh://wmscr1.dr.dk/e02ch03m

With negative stride, the start of the edge_emu buffer should be pointing to
the last line, not the end of the buffer.
With positive stride, pointing to the end of the buffer was completely wrong.
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.
