This reverts commit 9b25f3067485b32442e13964df098903736c3fd8 to
reinstate the reverted commit with fixes that solved the build issues
when --enalbe-clpf is used in configure.

These signals were in the uncompressed frame header (as a temporary
hack), which caused two problems:
* We don't want that header to be duplicated in the slice header
* It was necessary to signal the number of bits to transmit up front
However, the filter size can be 128x128 which is greater than the SB
size, and a decoder wouldn't be able to know whether to read a bit or
not until the final SB of that 128x128 block has been decoded
(depending on whether the 128x128 is all skip or not). Therefore the
signalling was changed for 128x128 blocks so that every top left SB of
a 128x128 filter block contains a signal regardless of whether the
block is all skip or not. Also, all the MB's of 128x128 block are
filtered even if they are skip MB's. This gives the signal a purpose
even when the 128x128 block is all skip, and it also gives a slight
coding gain as it leaves a way to filter skip blocks, which was
previously forbidden.

* Move clipping tests from inside to outside loops
* Let sizex and sizey to clpf_block() be the clipped block size rather
than both just bs
* Make fallback tests to C more accurate

When CLPF was extended to chroma, the chroma RDO accidentally
discarded the optimal block size found in the luma RDO.

av1_clpf_frame() was always called with the same src and dst,
so we only need one argument and the code supporting different
src and dst was removed.

Instead of having CLPF write to an entire new frame and
copy the result back into the original frame, make the
filter able to work in-place by keeping a buffer of size
frame_width*filter_block_size and delay the write-back
by one filter_block_size row.
This reduces the cycles spent in the filter to ~75%.
