MV struct was ussed to indicate the postition of a MI_BLOCK with row
and col components. The expression was confusing, this commit added a
new stucture "POSITION" with row and col component to better describe
the position of a mi_block.

Various cleanups and refactoring.
Removes feedback of active worst qaulity and uses last_q
instead to make the interface cleaner. Active worst quality
is now decided only once for a frame being coded in the
beginning based on last_q and other stats. Also, adds other
cleaups on last_q to store also the last_q for altref frames,
and reduces the altref interval a little.

The output does change a little.

This commit enables an adaptive prediction filter type selection
for sub8x8 block sizes. In speed 1, it re-uses the filter type of
collocated 8x8 block if it is tested in the rate-distortion optimization
loop, for the sub8x8 blocks. Otherwise, it runs the normal test
over all the three filter types. In speed 2, it re-uses the 8x8
block's prediction filter type, if available. Otherwise, force it
to be EIGHTTAP.

Compression and speed performance wise:
