This reverts commit 4a8fc1d8.

The commit caused null pointer derefernces when using udp://
after i fixed that it caused ffmpeg to get stuck and remapped
arguments like ?ttl=255 -> ?ttl%3d255

I dont want to leave this broken thus temporary revert so we all
have some time to look at this without half the network protocols
being broken in the meantime

In particular, fix trac ticket #2031.

This helps us not to make bad decision (frame dropping, audio compensation)
right after seeking when we do not know yet the recent audio or video clock.

The external assembly function uses mmxext instructions and should not be
masqueraded as an mmx-only function. Instead, use the mmx-only inline
assembly function.
