Precalculated block ptrs do not need updates during encoding.
Set these at init stage.

Moved the allocation of 'mt_current_mb_col' (last encoded MB on each
row) to vp8_alloc_compressor_data(), so that it is correctly
reallocated when frame size is changing.

Added drop_frame support in multi-resolution encoder.

If one frame is dropped at a lower-resolution level, the next
upper-resolution level encoder needs to encode that frame
independently without any lower-resolution level motion
information.

Another issue is that if one frame is dropped at some but not all
resolution levels, a frame after that one may use different set
of reference frames at different resolution levels. This reference
frame asynchronization could degrade motion search precision in
upper-resolution level encoding, which uses lower-resolution level
motion result. This change compares the lower-resolution and upper-
resolution level's reference frames. If they are not the same, the
upper-resolution level encoder can not use lower-resolution level
motion result.

Added validity checking in multi-res encoder. Disable spatial
resampling and frame dropping before we have those supports.
Also, deallocate the memory for all resolution levels once error
occurs.

This unit test tests vp8_sixtap_predict function against preset
data and random generated data. The test against preset data
checks the correctness of the functions, and the test against
random data checks if the optimized six-tap predictor functions
generate matching result as the c functions. It tests the
following functions:
vp8_sixtap_predict16x16_c
vp8_sixtap_predict16x16_mmx
vp8_sixtap_predict16x16_sse2
vp8_sixtap_predict16x16_ssse3

vp8_sixtap_predict8x8_c
vp8_sixtap_predict8x8_mmx
vp8_sixtap_predict8x8_sse2
vp8_sixtap_predict8x8_ssse3

vp8_sixtap_predict8x4_c
vp8_sixtap_predict8x4_mmx
vp8_sixtap_predict8x4_sse2
vp8_sixtap_predict8x4_ssse3

vp8_sixtap_predict4x4_c

This patch fixed issue 458 by calling copy function when both
offsets are 0, which guarantees the SSSE3 functions output
same result as the c function for all possible offsets.

xd->subpixel_predict16x16 is called in first pass, but isn't
initialized in first pass, which causes segfault. This patch
fixed that problem.

We need an easy way to build the unit test driver without running the
tests. This enables passing options like --gtest_filter to the
executable, which can't be done very cleanly when running under
`make test`.

Fixed a number of compiler errors/warnings when building the tests
in various configurations by Jenkins.
