These two flags serve essentially the same purpose, so we can
simplify down to just having one flag. Since the
frame_id_numbers_present_flag is older and listed in the
reference-buffer design doc, this is the one we'll keep.

Note that, previously, frame_id_numbers_present_flag was only
sent when CONFIG_OBU was enabled - otherwise it was always set
to 1. On the other hand, use_reference_buffer was always signalled
so that allowed us to disable frame ids even without CONFIG_OBU.

In order to keep the ability to disable frame IDs without
CONFIG_OBU, we send a "real" sequence header (ie, with the same
data as in CONFIG_OBU) in-line within the uncompressed header.
This is sent every keyframe and every intra-only frame, just
as the use_reference_buffer flag was before this patch.

Before LOOPFILTER_LEVEL, there's one filter level,
now we have four filter levels for y plane vertical,
y plane horizontal, u plane and v plane.

This patch enables experiment LOOPFILTER_LEVEL to support per
superblock loop filter level update.

CMake build updates:

- The conflict with warped_motion has been resolved.
- This also resolves a configure build mismatch with
  ncobmc_adapt_weight: warped_motion forcing it to off
  caused the mismatch.

This specialisation can't work: it gets the configuration to use from
av1_get_fwd_txfm_64x64_cfg, which specifies a TXFM_TYPE equal to
TXFM_TYPE_DCT64 (reasonable enough), but the code in
av1_fwd_txfm2d_sse4.c only supports TXFM_TYPE_DCT32 and
TXFM_TYPE_ADST32.

This patch removes the restriction that both rect_tx and var_tx must be
 turned off when any daala transform is enabled.
For now, all square transforms are done using daala with the rectangular
 transforms done using AV1.

transmitted before the frames.

This experiment was provisionally adopted on 2017-9-12

The ResizeCspTest unit test is disabled when intra_edge is enabled,
as the PSNR of the first frame increases from 77dB to 100dB.
This results in a failure when later frames are compared with the
first one.
