MSVC can't pass the address of global variables in a DLL correctly
across DLL boundaries. This patch allows linking the examples to
a libvpx dll build. Fixes issue #268.

1.5% (good, speed 5).

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.

Currently, when the video frame width is not multiples of 16, the
source buffer has a stride of non-multiples of 16, which forces
an unaligned load in SAD function and hurts the performance. To
avoid that, this change allocates source buffers to be multiples
of 16.

vpx_free if used contains this check. If replaced, well behaved free
