The do_post_rounding flag can now be removed since it is equivalent
to is_compound.

Change-Id: I3a18d853571b7363a87e65601c82d1f345b3dcd2

This patch simplifies the setting and use of the do_post_rounding
flag consistently across all convolve/warp operations. It is always
set now to 1 for compound modes, but the masked blending operation
can subsequently turn it off.
To accomplish this, for the warped case, the use of the conv_params->dst
buffer is made consistent with the other non-warp convolves,
in the sense that it is used only when is_compound is 1.

frames, no frame refs signaling options will be provided. Hence no
additional bit is added and the reference frame signaling stays the
same as baseline.

One bit is added to the frame header, to signal whether the references
for inter frames will be short-signaled.

When the bit is set, only 6 bits are used at the frame header level to
signal the choices of LAST_FRAME and GOLDEN_FRAME out of the eight
buffered references. All the other 5 references will be specified
using the frame offset info. Hence, compared to the baseline, the use
of frame_refs_signaling provides 2 scenarios:

(1) Reference short-signaling:
    3*7 - (1+3*2) = 14 bits are saved in the frame header;
(2) Reference regular-signaling:
    1 bit is added to the frame header.

- Fixed SSE4.1 implementation of the highbd warp filter.
- Removed the SSE2 and SSSE3 implementations of both the lowbd and highbd
  versions of the warp filter, as these will not work with CONFIG_JNT_COMP=1.

- The warp filter tests have been correspondingly updated.

Allow the CDF update to operate in different modes, e.g. update vs no
update.

The update mode is transmitted in the uncompressed frame header of
every keyframe and intra-only frame.

This patch only adds bitstream signaling and API support. The
implementation of the update modes will be in later patches.
