Avoid changing the public API based on an experiment flag:

- Remove aom_config.h include from aom_image.h.
- Unconditionally include the existing API additions.
- Add some missing doc comments (silences Doxygen warnings).
- Return an error when using ctrl flags that require
  CONFIG_COLORSPACE_HEADERS when it's not enabled.
- Move colorspace_headers to the correct section of configure.
- Move CONFIG_COLORSPACE_HEADERS to the correct section of
  aom_config_defaults.cmake.
- clang-format style check appeasement

Use --tune=[cdef-dist|daala-dist] to enable them.

Also, this commit set the use_activity_masking of PVQ as 0 by deafult,
which means that PVQ assumes daala-dist is not used by default.

Since we're currently not signaling which metric the encoder did use
in the bitstream, the compile flag AV1_PVQ_ENABLE_ACTIVITY_MASKING will tell PVQ
whether daala-dist is used or not.

This commit is the last part of prep-work to remove DIST_8X8, CDEF_DIST,
and DAALA_DIST experimental flags.

Even if 'dist-8x8' is enabled with configure,
the dist-8x8 is not acutally enabled (so, no change in encoding behaviour)
until the command line option, '--enable-dist-8x8=1" is used.

When ext-comp-refs is enabled, one-sided-compound is enabled by default,
which ensures the use of ext-comp-refs is an extension of
one-sided-compound. Both coding tools allow the use of same-sided
reference frame pairs for compound prediction.

Also, remove the dependency of ext-comp-refs on var-refs, i.e. these two
coding tools can be independently enabled. They can still work together
if both are enabled simultaneously.

Before this patch, the functions build_inter_predictors, allow_warp
and av1_make_inter_predictor took two parameters (if
CONFIG_MOTION_VAR): mi_col_offset and mi_row_offset. These were used
for two things: they were used to look up a MODE_INFO structure and
the code figured out it was doing OBMC if at least one offset was
nonzero.

This patch slightly simplifies things by passing the relevant mi and a
flag saying whether we're doing OBMC instead. This means the
allow_warp function actually loses a parameter.

It also moves all mention of the functions out of the header and into
reconinter.c since they are only used in that compilation unit.

CONFIG_DAALA_DCT4 currently force-enables CONFIG_DCT_ONLY due to a
missing 4-point DST.  The DST had not been included because it was a
significant coding performance loss; this turned out to be a bug that
has since been corrected.

This patch adds a 4-point type IV DST to the DAALA_DCT4 experiment.
There is a small coding performance loss in using the type IV over
AV1's current type VII.

aom_dsp_rtcd_defs.pl compares most CONFIG_* keys to "yes"
to see if they're set. The script was checking just

  if (aom_config("CONFIG_EXT_PARTITION_TYPES"))

in some cases. The build system doesn't add disabled
configuration options to libs.mk so this is effectively
the same, however it means that setting the config
key explicitly to 0 or "no" in the config headers
was treated the same as setting it to 1 or "yes",
and aom_dsp_rtcd.h would have opposite expections
from aom_config.h or aom_config.asm.

Treat this key similarly to others for consistency.

* When wedge and compound-segment are disabled, we don't use
  compound_type_cdf, but it still gets copied around, averaged, etc.
  It's slightly nicer to avoid that when it isn't necessary.

  'if (bsize < 8X8 && CB4X4)', which is backwards when compared to
  other similar conditions elsewhere in the code.
  Change this to 'if (bsize < 8X8 && !CB4X4)" to match other code.

In av1/av1_cx_iface.c the encoder_encode function loops over calls made
to av1_get_compressed_data(). If the show_existing_frame flag is set,
the frame has already been flushed and the av1_twopass_postencode_update
function already incremented gf group index. The loop must exit, or else
the superframe might contain multiple shown frames. This causes a
mismatch in the test_decode function in that
av1_cx_iface.c:ctrl_get_new_frame_image will return the frame at
last_show_frame_buf_idx whereas, av1_dx_iface.c:ctrl_get_new_frame_image
