Prepare for 11_alpha1 Release
build: Drop stray mpc8 decoder dependency on dsputil
build: Drop stray PNG decoder dependency on dsputil
build: Drop stray MLP decoder dependency on dsputil
build: Drop stray MJPEG encoder dependency on dsputil
build: Drop stray LPC dependency on dsputil
ffv1: Drop bogus dependency on dsputil

ffv1 does not use any part of the dsputil framework.
configure: Add explicit dsputil dependency to mpegvideoenc

Previously, it was an implicit dependency through mpegvideo. Change
this, as implicit dependencies can cause all sorts of trouble.
build: Record dependency of eatqi decoder on dsputil
Remove all SH4 architecture optimizations

SH4 has been end-of-lifed and no more test machines are available.

If someone wants to maintain these (or other) SH4 optimizations, please
contact me or ffmpeg-devel.
I am happy to revert this removial if theres someone considering to
maintain this code.
