When DAALA_EC is enabled, calls to aom_read_tree() and aom_write_tree()
would automatically convert the aom_tree_index and aom_prob into a CDF
and call the aom_read_cdf() or aom_write_cdf(), which causes an
error if DAALA_EC is enabled without EC_MULTISYMBOL.
This patch moves the conversion functions from daalaboolreader.h and
daalaboolwriter.h into bitreader.h and bitwriter.h respectively, and
only calls the conversion functions if EC_MULTISYMBOL is enabled.
This allows DAALA_EC to be enabled without EC_MULTISYMBOL and is a
bitstream change when both ANS and EC_MULTISYMBOL are enabled as calls
to read and write trees will automatically be converted into calls that
read and write cdfs.

the SSE flags since they're not needed with MSVC.

When global-motion is enabled, a considerable amount
of encoder time is spent in the functions in corner_match.c.
This patch optimizes those functions to be 3.5-4x as fast,
leading to an end-to-end encoder speed improvement
(on 20 frames of tempete_cif.y4m) of:
200kbps: ~26% faster
800kbps: ~19% faster
2800kbps: ~12% faster

Wedges were wrongly indexed when cb4x4 was on.

strip the default eol from the config header line, then a '\r' if there
is one. this can occur if cmake used to output the header uses windows
eol, but the perl used expects newlines for instance.

This saves the cost of encoding one symbol per partition. Currently in
practice this is usually the last DCT token sign so it saves one bit.
Most of the time these gains aren't realized but occasionally it makes
the final state one byte smaller or saves one renormalization.

The reference frame handling in av1_find_mv_refs introduced
in https://aomedia-review.googlesource.com/c/6067/ broke the
compile when global-motion is enabled but ref-mv is not.
This patch adds the missing logic, allowing this case to compile
again.

The WienerInfo struct requires a 16-byte alignment on x86,
since it contains filter coefficients which are loaded using
SSE aligned load instructions. But on 32-bit x86, the default
alignment of aom_malloc/aom_realloc is only 8 bytes, leading
to occasional segfaults.
To fix this, rather than using aom_realloc to resize WienerInfo
structures, we always free and re-allocate them using aom_memalign

Noticed that some ALTREF_FRAMEs could have used compound modes for its
prediction but have been labeled as SINGLE_REFERENCE mode in the frame
header. This experiment is to remove the COMPOUND_REFERENCE mode from
the frame-level reference mode choices and only leave SINGLE_REFERENCE
and REFERENCE_MODE_SELECT the two choices in the frame header.
When turning on both ext-refs and ref-adapt, compared against ext-refs
itself, a small gain is achieved. In PSNR, the bitrate saving gains are
as follows:
lowres: Avg -0.120%; BDRate -0.128%
midres: Avg -0.155%; BDRate -0.128%

CLPF performance had degraded by about 0.5% over the past six months,
which isn't totally surprising since the codec is a moving target.
About half of that degradation comes from the improved 7 bit filter
coefficients. Therefore, CLPF needs to be retuned for the current
codec.
This patch makes two (normative) changes to the CLPF kernel:
* The clipping function was changed from clamp(x, -s, s) to
sign(x) * max(0, abs(x) - max(0, abs(x) - s +
(abs(x) >> (bitdepth - 3 - log2(s)))))
This adds a rampdown to 0 at -32 and 32 (for 8 bit, -128 & 128
for 10 bit, etc), so large differences are ignored.
* 8 taps instead of 6 taps:
1
4 3
13 31 -> 13 31

About 3/4 of the gains come from the new clipping function.
