LibVideo/VP9: Select and read motion vectors without fields in Parser

Browse source 
Candidate vector selections are only used to calculate the new vectors
for the current block, so we only need to keep those for the duration
of the inter_block_mode_info() call.

Candidate vectors are now stored in BlockMotionVectorCandidates, which
contains the fields necessary to choose the vector to use to sample
from the selected reference frame.

Most functions related to motion vectors were renamed to more verbose
but meaningful names.
