rtmp: Allocate the prev_pkt arrays dynamically

Normally, all channel ids are between 0 and 10, while they in
uncommon cases can have values up to 64k.

This avoids allocating two arrays for up to 64k entries (at a total
of over 6 MB in size) each when most of them aren't used at all.

avresample/x86: Switch operand order for mulps

With the forthcoming VEX instruction emulation, mulps
must have only the third operand point to memory, as
this is what vmulps expects.

x86inc: Use VEX-encoded instructions in AVX functions

Automatically use VEX-encoding in AVX/AVX2/XOP/FMA3/FMA4
functions for all instructions that exists in a VEX-encoded
version.

This change makes it easier to extend existing code to use AVX2.

Also add support for AVX emulation of a few instructions that
were missing before.
