vc1dec: Invoke edge_emulation regardless of MV precision
In VC-1 interlaced field pictures, chroma motion vectors can extend beyond
picture boundary even if luma vectors are bounded. The problem shows up
only for hpel interpolated MVs, and may be due to the way motion vectors
are scaled / cropped.
Thanks to Konstantin Shishkov for suggesting the fix. This fixes
long-known segfaults in MC-VC1.ts from videolan streams archive.

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.

tls: Return AVERROR_EOF if the TLS_read/write functions return 0
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.
