Also rename the enum values to be consistent with other DCT permutations.

This will pick the "best" simple idct compatible idct

This avoids recalculating the value over and over again.

It does not help as an abstraction and adds dsputil dependencies.

Move some functions from dsputil. The idea is that videodsp contains
functions that are useful for a large and varied set of video decoders.
Currently, it contains emulated_edge_mc() and prefetch().

The new lowres support is limited to decoders where lowres decoding
is possible in high quality.
I was not able to measure any speed difference, but if one is found
the 2-3 lines that might affect speed can be made compile time conditional

This feature is complex, of questionable utility, and slows down
normal decoding.

Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.'  to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".

or a single loop similar to what mplayer uses
