Rename ff_put_string to avpriv_put_string
This allows using it from libavformat as well. This will be used
by the RTP/JPEG depacketizer.

swscale: Provide the right alignment for external mmx asm
This reverts parts of
e0c6cce4472. There is external mmx asm that
requires this alignment.
This fixes crashes when using swscale in builds with external mmx,
without inline assembly.

This separates code relying on inline from that relying on external
