Don't invent a bogus EIO error.

The code now doesn't check for ret == 0, but that check is redundant,
av_get_packet() never returns 0.

64-bit CPUs always have SSE2, and a SSE2 version exists, thus the MMX
version will never be used.

This allows non-standard replacements for the -c compiler flag.
Some compilers use other flags or no flag at all in place of
the usual one.

This allows using non-standard flags for running the C preprocessor.
The -o flag must be included in this setting due to strange syntax
required by some compilers.

Set the correct flags for tms470.

Previously, we returned any error code except AVERROR_EOF to the
caller - only if AVERROR_EOF or 0 was returned, we proceeded to
the next segment.

With some setups of web servers, using Connection: close in https
and GnuTLS, we don't get a clean error code at the end of segments.
In those cases, just proceed to the next segment.

OpenSSL returns 0 when the peer has closed the connection. GnuTLS
doesn't return that though, but returns
GNUTLS_E_UNEXPECTED_PACKET_LENGTH if the connection simply is closed
without a clean close notify packet.

All x86-64 CPUs have SSE2, so the MMX version will never be used. This
leads to smaller binaries.

Removes a false dependency on existing contents of the 2nd dst register,
giving better performance for OOE.

Allow substitution of channel pairs in the input for nearby channel pairs in
the output in order to get a closer match. Also weigh LFE channel mismatch
differently to favor matching the same layout without LFE over one less
channel with LFE.

This will give a clearer error message when the error is caused by a
truncated packet.

Reversing the lpc coefficient order simplifies indexing in the filter.

Adds optimized functions for mixing 3 through 8 input channels to 1 and 2
output channels in fltp or s16p format with flt coeffs.

This adds a full identification probe of CC, AS, LD and HOSTCC,
and sets up correct flags and dependency tracking for each.
