move to encoder_encode() as vp10_get_compressed_data() allocates data and
would require some modification to make its error return meaningful.

allocations done within this function are protected with
vpx_internal_error; adding the setjmp fixes a crash in
vp10_lookahead_push() under low memory conditions.

Fixes an issue where the tx_type was not set correctly for
sub8x8 inter and intra blocks. In the current syntax, for
sub8x8 blocks, there is still a single tx_type that is
transmitted. Ideally, this should be searched for the best
rd performance, albeit at the expense of encode speed.
For now, we just set it to DCT_DCT. Previously it was left
incorrectly as what was used for the previous non sub8x8
block.

The definition is for the number of frames to check to determine the
recent decay rate, further to determine the next key frame in the
first pass of the encoder.

the lookahead buffer allocation is deferred to receipt of the first
frame to allow profile changes. if the encoder was flushed before
supplying any frames the encoder would crash trying to dereference the
NULL buffer. vp8 is unaffected.

This commit adds the logic for segmentation map initialization and
disable temporal update of segmentation map when error-resilient
mode is on. It fixes the enc/dec mistmates (release build) and
assertions(debug) when both aq-mode and error-resilient are on.

The nominal tx_type for a given mode is used as a context
to encode the actual tx_type for intra.

Otherwise, per-segment lossless might mean that some segments are not
lossless and they could still want to use another mode. The per-block
tx points remain uncoded on blocks where (per the segment id) the Q
value implies lossless.

For testing implemented a fixed pattern and delta, 1 pass,
fixed Q, low delay mode.
This has not in any way been tuned or optimized.

(copied from VP9)
The one pass VBR mode selects a Q range based on a
moving average of recent Q values. This calculation
should have been excluding arf overlay frames as these
are usually coded at the highest allowed value. Their
inclusion skews the average and can cause it to drift
upwards even when the clip as a whole is undershooting.
As such it can undermine correct adaptation of the allowed
Q range especially for easy content.

The culprit is on the decode side xd->lossless[i] setup was in wrong
location where segment features are not yet decoded.
Also on the encoder side, transform mode was not set consistently
between when tx_mode is selected and how tx_mode is enforced in
tx size selection.
