Set bounds from the array when iterating mmaps.
The mmap allocation code in vp8_dx_iface.c was inconsistent.
The static array vp8_mem_req_segs defines two descriptors,
but only the first is real. The second is a sentinel and
isn't actually allocated, so vpx_codec_alg_priv is declared
with mmaps[NELEMENTS(vp8_mem_req_segs)-1]. Some functions
use this reduced upper bound when iterating though the mmap
array, but these two functions did not.
Instead, this commit calls NELEMENTS(...->mmaps) to directly
query the bounds of the dereferenced array.
This fixes an array-bounds warning from gcc 4.6 on
vp8_xma_set_mmap.

Removed firstpass motion map

each MB indicating how strongly the firstpass code
believes it should be filtered during the second pass
ARNR filtering.
For long or large format material the motion map can
become extremely large and hamper the operation of
the encoding process.
This change removes the motion map altogether, leaving
the second pass to rely on the magnitude of the motion
compensated error to determine the filter weight to
use for the MB during ARNR filtering.
Tests on the derf set indicate that the effect of this
change is neutral, with some small wins and losses. The
motion map has therefore been removed based on

Fix drastic undershoot in long form content

cast to int resulted in a negative value, causing the rate control to
allocate no bits to that keyframe group, leading to severe undershoot

This error was exposed by the recent change to the rolling target and
actual spend accumulators in commit

actually calculate the average value rather than be re-initialized
on every frame to the average per-frame bitrate. When this bug was
triggered, the target bitrate could be 0, so the rolling target
becomes small, which causes the undershoot. The code prior to
305be4e4
did not exhibit this behavior because the rolling target was always
set to a reasonable value and was independent of the actual target
bitrate. With this patch, the actual target bitrate is calculated
correctly, and the rate control tracks as expected.
This cast was likely added to silence a compiler warning on a comparison
between a double (modified_error_left) and an int (0). Instead, this
patch removes the cast and changes the comparison to be against 0.0,
which should prevent the warning from reoccuring.
This fixes issue #289. Special thanks to gnafu for his efforts in
reporting and debugging this fix.

change CFLAGS for 64 bit icc builds
AMD64 only implies SSE2, not SSE3. There aren't any known cases where
icc was generating SSE3 instructions since all the vectorizable code
is already in handwritten asm, so this fix is included mostly for
correctness. Fixes issue #259.

Overflow of frame error accumulators.
This fixes an overflow problem in the frame error accumulators.
The overflow condition is extreme but did trigger when Frank B.
coded some high motion interlaced HD content.
The observed effect was a catastrophic breakdown of the rate
control leading to massive undershoot and poor bit allocation.
All the error values should really be unsigned but I will look at this
separately.
