Limit size of initial keyframe in one-pass.
Rather than using a default size of 1/2 or 3/2 seconds for the first

This will likely undergo further refinement as size limits on key
frames are currently under discussion on codec-devel@, but this gives
much better behavior for small buffer sizes as a starting point.

Generate a vpx.pc file for pkg-config.

Ralph Giles [Mon, 28 Mar 2011 19:04:51 +0000 (12:04 -0700)]
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.

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.

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.

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.
