Rename MI_BLOCK_SIZE.* -> MAX_MIB_SIZE.* (MIB is for MI Block).
Rename MI_MASK.* -> MAX_MIB_MASK.*
There are no functional changes.
This is in preparation for coding the superblock size at the frame
level, which will require some of these constants to become variables.
The new names better reflect future semantics, and hence make the code
clearer.

If --enable-ext-partition is used at build time, the superblock size
(sometimes also referred to as coding unit (CU) size) is extended to
128x128 pixels.

Adds a wiener filter based restoration scheme in loop which can
be optionally selected instead of the bilateral filter.
The LMMSE filter generated per frame is a separable symmetric 7
tap filter. Three parameters for each of horizontal and vertical
filters are transmitted in the bitstream. The fourth parameter
is obtained assuming the sum is normalized to 1.
Also integerizes the bilateral filters, along with other
refactoring necessary in order to support the new switchable
restoration type framework.
derflr: -0.75% BDRATE
[A lot of videos still prefer bilateral, however since many frames
now use the simpler separable filter, the decoding speed is
much better].
Further experiments to follow, related to replacing the bilateral.

Current implementation is a bilateral filter whose
parameters are transmitted in the bitstream.
derflr: -0.647% BDRATE
hevcmr: -0.794% BDRATE
This is a prelimary patch. Various other variations are to
be investigated next, that will hopefully be less expensive
on the decoder side.

Under the experiment of EXT_REFS: LAST2_FRAME, LAST3_FRAME, and
LAST4_FRAME.
Coding efficiency: derflr +1.601%; hevchr +1.895%
Speed: Encoder slowed down by ~75%

Remove MISC_FIXES flags except for the changes on MV precision, which
has a 0.1% performance drop.
On derflr, the impact is -0.012%.
