Bitmask patch 2: Applying filtering once bitmask is built

(1). Apply loop filtering after bitmask is built.
This process is decoder only because the bitmask info is stored
at decoding time. For encoder, loop filter should go through
original path.

(2).Apply filtering first vertically and then horizontally for
each superblock. This way is preferred since is goes through
buffer only once.

(3). Call dual filter functions correctly, since bitmask enables it.
