Input MV needs to be modified to full-pixel precision.

The error accumulator stats values cpi->prediction_error and
cpi->intra_error were being populated with rd values not
distortion values.

These are only "currently" used in a limited way for RT compress
key frame detection.

except for 32bit. only a slight improvment there.

MV sad cost error is only used in full-pixel motion search,
which only need full-pixel resolution instead of quarter-pixel
resolution. This change reduced mvsadcost table size, and
removed unneccessary pamameter passing since this table is
constant once it is generated.

cygwin doesn't support _sopen. drop down to the lowest common
denominator and merge main for all platforms. this also opens the door
for supporting multiple object formats with a single binary.

rather than look up rc in the zig zag table, embed it in the macro. this
also allows us to shuffle some values in the macro and keep *d in rsi

gains of about the same order as the obj_int_extract implementation: ~2%

Address calculations moved from encodemb_arm.c file to neon
optimized assembly function to save cycles in function calls.
 - vp8_subtract_b_neon_func replaced with vp8_subtract_b_neon
   that contains all needed address calculations
 - unnecessary file encodemb_arm.c removed
 - consistent with ARMv6 optimized version

* changes:
  Generate a vpx.pc file for pkg-config.
  Export the version string as a makefile variable.

Rules are added to libs.mk to generate a vpx.pc, which is
installed as pkgconfig/vpx.pc under the target library directory.
This also requires the install path prefix be exported directly
in config.mk.

Some systems use a tool called pkg-config to query information
about intalled libraries or other resources, based on database
files provided by the packages themselves at install time.

Providing such a file for libvpx simplifies integration with
other build systems, and provides an easy avenue for developers
to test against their own builds of the library.

The configure script exports the major/minor/patch version
numbers, but didn't make the full version string available
to Makefile recipes and rules, the way it is available to
C code from vpx_version.h.

After picking filter level, post the loopfilter semaphore

Identified as a possible cause of issue #308, the code was silently
ignoring realloc failures, which would lead to corruption, memory
leaks, and likely a crash. The best we can do in this case is die
gracefully.

Adds following ARMv6 optimized functions to encoder:
  - vp8_subtract_b_armv6
  - vp8_subtract_mby_armv6
  - vp8_subtract_mbuv_armv6

Gives 1-5% speed-up depending on input sequence and encoding
parameters. Functions have one stall cycle inside the loop body
on Cortex pipeline.

now that we need asm_enc_offsets.c for x86 and arm and it is
harmless to build it for other targets, add it unconditionally

Half pixel interpolations optimized in variance calculations. Separate
function calls to vp8_filter_block2d_bil_x_pass_armv6 are avoided.On
average, performance improvement is 6-7% for VGA@30fps sequences.

remove helper function and avoid shadowing all the arguments to the
stack on 64bit systems

when running with --good --cpu-used=0:
~2% on linux x86 and x86_64
~2% on win32 x86 msys and visual studio
more on darwin10 x86_64
significantly more on
