Adjustment previously only enabled in VBR mode.

This patch allows adjustment of min and max q for CBR
and adjustment of max q only for CQ mode.

  Don't copy thread data for the main thread.

The first value of video->frame() is 15 because of the source range used.

It was tiny when it was orginally marked INLINE. Forcing this function
to be inlined prevents the compiler from inlining its much smaller
callers.

No measurable speed impact, 28320 byte smaller libvpx.a

Visual Studio is exceptionally picky about this:

Make it a general purpose fast motion estimation function, to be
used in the mode search process.

This saves an extra 64x64 variance calculation and replaces two
32x32 variance functions with sad functions. The compression
performance change is unnoticeable.

Frame buffers are now allocated dynamically on-demand.

Entries in the reference frame map, cm->ref_frame_map,
may now be set to -1 (INVALID_IDX) to indicate that
there is not a valid reference buffer in that "slot".

All slots in the reference frame map are now initialized
to the empty state (-1) and each buffer is initialized
to have a reference count of 0.

Use rectangular block size for integral projection motion estimation
if the the 64x64 block has over half block outside the frame. This
avoids the issue that the motion information of these blocks is
dominated by the extended pixels, instead of the pixels of interest.

The rounding factor needs to be scaled down by a factor of 2.
Also, the quantized and dequantized coefficients are memset to 0
when dc quantizer is used.
