6b7cf3077d doxy: fix conditional usage, ref warnings
doxygen < 1.7.? seems to have been more tolerant of single line
\if/\endif

This change fixes warnings such as:
mainpage.dox:13: warning: unable to resolve reference to `vp8_encoder-'
for \ref command
vpx_decoder.h:193: warning: explicit link request to 'n' could not be
resolved

20cd3e6b8f fix potential use of uninitialized rate_y
This issue likely doesn't appear in the unmodified encoder, but
sufficient hacking on the mode selection loop can expose it.

aabae97e57 vpxenc: fix time and fps calculation in 2-pass encoding
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.

52cf4dcaea Packing bitstream on-the-fly with delayed context updates
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

version of vp8_intra4x4_predict.  Future commits will fix this
code duplication.

019384f2d3 Only do uv intra-mode evaluation when intra mode is checked
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.

507ee87e3e Remove the frame rate factor for key frame size.
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.
