Coefficient costing failed to take account of the first branch
being skipped ( 0 vs eob) if the previous token is 0.

Fixed rd to account for slightly increased token cost & cleaned up
warning message

Propagate debug setting to the EBML struct. When writing the application
name, this allows us to strip the version code and keep the output
metadata static.

When we do 2-pass encoding, elapsed time is accumulated through
whole 2-pass process, which gives incorrect time and fps results
for second pass. This change fixed that by resetting the time
accumulator for second pass.

Produce the token partitions on-the-fly, while processing each MB.
Context is updated at the beginning of each frame based on the
previoud frame's counters. Optimally encoder outputs partitions in
separate buffers. For frame based output, partitions are concatenated
internally.

Limitations:
    - enabled just in combination with realtime-only mode
    - number of encoding threads has to be equal or less than the
    number of token partitions. For this reason, by default the encoder
    will do 8 token partitions.
    - vpxenc supports partition output (-P) just in combination with
    IVF output format (--ivf)

Performance:
    - Realtime encoder can be up to 13% faster (ARM) depending on the number
    of threads and bitrate settings. Constant gain over the 5-16 speed
    range.
    - Token buffer reduced from one frame to 8 MBs

Quality:
    - quality is affected by the delayed context updates. This again
    dependents on input material, speed and bitrate settings. For VC
    style input the loss seen is up to 0.2dB. If error-resilient=2
    mode is used than the effect of this change is negligible.

Example:
./configure --enable-realtime-only --enable-onthefly-bitpacking
./vpxenc --rt --end-usage=1 --fps=30000/1000 -w 640 -h 480
--target-bitrate=1000 --token-parts=3 --static-thresh=2000
--ivf -P -t 4 -o strm.ivf tanya_640x480.yuv

* changes:
  Eliminated reconintra_mt.c
  Eliminated vp8mt_build_intra_predictors_mbuv_s

Reworked the code to use vp8_build_intra_predictors_mby_s,
vp8_intra_prediction_down_copy, and vp8_intra4x4_predict_d_c
functions instead.  vp8_intra4x4_predict_d_c is a decoder-only
version of vp8_intra4x4_predict.  Future commits will fix this
code duplication.

When we encode slide-show clips, for the majority of the time,
only ZEROMV mode is checked, and all other modes are skipped.
This change delayed uv intra-mode evaluation until intra mode is
actually checked. This gave big performance gain for slide-show
video encoding (2nd pass gain: 18% to 28%). But, this change
doesn't help other types of videos.

Also, zbin_mode_boost is adjusted in mode-checking loop, which
causes bitstream mismatch before/after this change when --best
or --good with --cpu-used=0 are used.

When temporal layers is used (i.e., number_of_layers > 1),
we don't use the frame rate boost for setting the key
frame target size. The factor was forcing the target size to be
always at its minimum (2* per_frame_bandwidth) for low frame rates
(i.e., base layer frame rate).

Generally we should modify or remove this frame rate factor;
for now we turn if off for number_of_layers > 1.

In vp8_rd_pick_inter_mode(), if total of eobs is zero, rate needs
to be adjusted since there are no non-zero coefficients for
transmission. The uv intra eobs calculated in
rd_pick_intra_mbuv_mode() need to be saved before they are
overwritten by inter-mode eobs.

mode_info_context->mbmi.mb_skip_coeff has to always reflect the
existence or not of coeffs for a certain MB. The loopfilter needs this
info.
mb_skip_coeff is either set by the vp8_tokenize_mb or has to be set to
1 when the MB is skipped by mode selection. This has to be done
regardless of the mb_no_coeff_skip value.

prob_skip_false is needed just when mb_no_coeff_skip is 1. No need to
keep count of both skip_false and skip_true as they are complementary
(skip_true+skip_false = total_mbs)
