This fix added MV range checks for NEWMV mode as suggested by Jim.
To reduce unnecessary MV range checks, I tried Yaowu's suggestion.
Update UMV borders in NEWMV mode to also cover MV range check.
Also, in this way, every MV that is valid gets checked in diamond
search function.

The MV's range is 256. Since the new motion search uses a different
starting MV than the center ref MV, a MV range checking needs to
be done to avoid corruption.

Per John's previous change, shrink TOKENEXTRA from 20 to 8 bytes

Also drop unused field from vp8_extra_bit_struct
Update ARM ASM to deal with this change. In particular, Extra is signed
and needs to be sign-extended when loaded.

This code is unused, as the current preproc implementation uses the
same spatial filter that postproc uses.

Change the size of structure elements to reduce memory utilization.
Removed the 'section' member entirely, as it is set but never read.

read_frame would incorrectly insert detect->buf into img
for ivf files. detect->position now set to 4 if input file is
detected to be ivf in file_is_ivf to keep this from occuring.

Added the initialization of the pointer to active map. Also added the
same logic for cyclic refresh in mbrow encoding threads.

Changed the end of block computation to use pmaxw. Removed
additional pushing and popping of registers that was not needed.

Change I3430820 performed an uninitialized read when
encode_breakout == 0, since the sum and sse wouldn't be set:
if(x->encode_breakout)
VARIANCE_INVOKE(..., get16x16var)(..., &sum, &sse);
if (cpi->active_map_enabled && x->active_ptr[0] == 0) {
...
} else if (sse < x->encode_breakout)

Corrected the initial Q range limits for the recode loop
to reflect the current allowed range for the frame.
In experimental work on constrained quality this bug was
causing unnecessary recodes.

This patch adds a weighting factor on RDMULT for UV blocks. The change
has an overall gain about 0.5% based on ssim, between 0.1 and 0.2% by
psnr numbers.

Deallocating the buffers before re-allocating them.
The fix passed James Berry's test program for memory
leak check.

Moved the code from the segmentation loop into a function
which is now called for each segment. This will allow us
to change the segment order checking more easily.

When auto_golden wasn't set it forced all frames to be a golden
frame. Now the manual configured frequency is adhered to.
