Use a simpler least-squares function for affine and rotzoom
model estimation, instead of computing the pseudo inverse.
Also refactors the code into a separate mathutils.h file.

The SVD code is currently used only for estimation of the
homography models which can be removed when we remove the
homography models.

Coding efficiency change is in noise range, with the small
difference coming from numerical precision issues.

Writes and reads alpha to and from the bitstream.

A special case is needed on the encoder side to handle prediction block
skips. Since whether or not a prediction block is skipped during CfL, a
rollback is required if the block was skipped and the alpha index was
not zero. The advantage of this is that no signaling is required when
the prediction block is skipped as it is assumed tha the alpha index is
zero.

A encode facade is added to the intra prediction facade as CfL requires
special encoder side operations.

this change enables loopfiltering_across_tiles by defualt after
it has been adopted. support in the deblocking filter and CDEF
filter has been implemented. a command line argument --tile-loopfilter

tile boundarys.

The aom_codec_stream_info struct had an `sz` field. It looks like
this was intended to implement polymorphism, where individual
codecs under the aom API could extend the struct with additional
members while maintaining common fields like frame size.

However, no codec-specific initializer was ever provided,
requiring callers to manually set this field to the expected
value. The extension mechanism isn't used by the av1 codec,
and also wasn't used by the vp8 or vp9 codecs in the libvpx
implementation.

Since it's not used, this commit removes the layer of indirection,
removing the confusing initialization burden and using
aom_codec_stream_info_t directly within the av1 decoder.

The SSSE3 filter is very similar to the SSE2 filter, but
the horizontal pass is sped up by using the 8x8->16
multiplies added in SSSE3.

Also apply const-correctness to all versions of the filter

The timings of the existing filters are unchanged, and the
lowbd SSSE3 filter is ~17% faster than the lowbd SSE2 filter.

Timings per 8x8 block:
lowbd SSE2: 320ns
lowbd SSSE3: 273ns
highbd SSSE3: 300ns

Filter output is unchanged.

This patch removes resize triggering by rate control and also removes
pending resizes causing recodes in encode_with_recode_loop. The removed
functionality will be replaced in the future, but it is simply being
removed for now to simplify the work to do.

This also avoids having 'bit_depth'/'bd' members whose presence
is decided by the preprocessor.

The goal is to simplify statements accessing the bitdepth value.
(instead of forcing them to also rely on the preprocessor to query
the member presence through #if CONFIG_HIGHBIDEPTH).

Builds will fail if configured with delta_q disabled and ext_delta_q not
also disabled, since ext_delta_q is soft enabled. This patch fixes this
by making the configure script disable ext_delta_q if delta_q is not
enabled.

Replaces resizing's table and index approach to frame sizes with
numerator and denominator integers in the AV1_COMP struct.

This approach is more flexible and will be simpler going forward as it
is much more similar to the 1-pass CBR approach that is also being
refactored. The intention is to merge both approaches and this is the
first step toward that.
