3d6815817c Use full-pixel MV in mvsadcost calculation
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.

fd7040d2b6 support obj_int_extract on cygwin
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.

8520b5c785 tweak vp8_regular_quantize_b_sse2
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%

cec76a36d6 Wrapper function removed from vp8_subtract_b_neon function call
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

297b27655e Runtime detection of available processor cores.
Detect the number of available cores and limit the thread allocation
accordingly. On decoder side limit the number of threads to the max
number of token partition.

Core detetction works on Windows and
Posix platforms, which define _SC_NPROCESSORS_ONLN or _SC_NPROC_ONLN.

607f8420f3 Generate a vpx.pc file for pkg-config.
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.

53e9987b4d Export the version string as a makefile variable.
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.

26b6a3b088 vpxenc: die on realloc failures
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.

6fdc9aa79f ARMv6 optimized subtract functions
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.

bfe803bda3 Fix multithreaded encoding for 1 MB wide frame
Thread synchronization was not correct when frame width was 1 MB.
Number of allocated encoding threads is limited by the sync_range.
There is no point having more because each thread lags sync_range MBs
behind the thread processing the row above.

429dc676b1 Increase static linkage, remove unused functions
A large number of functions were defined with external linkage, even
though they were only used from within one file. This patch changes
their linkage to static and removes the vp8_ prefix from their names,
which should make it more obvious to the reader that the function is
contained within the current translation unit. Functions that were
not referenced were removed.

These symbols were identified by:

  $ nm -A libvpx.a | sort -k3 | uniq -c -f2 | grep ' [A-Z] ' \
    | sort | grep '^ *1 '
