On a keyframe alt ref and golden are refreshed. The flag was
not being set and so on the frame after a keyframe, motion
search would occur on the alt ref frame. This is not necessary
because the alt ref frame identical to the last frame in this
scenario.
Handle corner case where a forward alt-ref frame is put
directly after a keyframe.

remove warning comment in vpxenc.c: in case of 1x1 picture,
detect_bytes will be equal to '3' and we'll fall back to
RAW_TYPE.
fix read_frame() by tracking the pre-read buffer length
in the struct detect

The sz member of the vpx_codec_stream_info_t structure must be
initialized when passed to vpx_codec_peek_stream_info().

The baseline bits per MB prediction tables have been
re calibrated based on the assumption that bits per mb
is inversely proportional to the quantizer level.

In the process of developing new intra prediction modes, tests have
shown removal of the low pass filtering from B_HE_PRED and B_VE_PRED
has an overall minor positive impact in both PSNR and SSIM metric.
Overall difference is about 0.1%. The change shall also have a small
positive impact on speed. Intuitively, this change should also reduce
some of the tendency of "flattening"

Changing the MAX_PSNR to 100 to allow testing of further experiments
on extending quantizer range to near lossless. With an effective
quantizer of 1, encoder achieves ~68DB, which is consistent with
fdct/idct round trip error.

Extending the value range of tokens allows further experiments on
extending quantizer range. Encoder and decoder were verified to
produce matching reconstructed buffers by tests with forced
quantized value of 1.

Replaced existing code to decide if a frame recode is required
with a function call. This is to simplify addition of extra clauses
that may be needed for the planned constrained quality mode.
Also fixed a bug where by alt ref not considered in the test.

The example for disabling the active map used a hard-coded 320x240
resolution, rather than using what was passed on the command line.

This function was never called in a context expecting a return value,
the return value was always a constant, and the !CONFIG_MULTITHREAD
path didn't have a return statement, which caused a compiler warning.
This patch changes the function to return void instead.
Fixes issue #231

The ERROR macro collides wiith the MS SDK on Windows. Since we're not
making any win32 calls in this function, just #undef it first to take
ownership.
