This patch adds mingw32 cross-compilation support to HandBrake trunk to

produce native win32 binaries. The main benefits are the binary does not have
any Cygwin runtime requirements and various host platforms can be leveraged
to build HandBrake.

Cross-compilation toolchains are complex to setup and recommended for experts
only; but once setup it can build at speeds similar to native builds,
on Darwin or Linux.

BUILD INSTRUCTIONS:
  Add mingw32 toolchain to beginning of your path and take the toolchain
  prefix from gcc (eg: i386-mingw32-gcc) and pass to configure:

    ./configure --cross=i386-ming32

PRODUCTS:
  - hb.lib (static library)
  - HandBrakeCLI.exe

DOWNLOADS:
  Contrib downloads need to be seeded with:
  - pthreads-w32-2-8-0-release.tar.gz (new)
  - xvidcore-20090311.tar.gz

SUMMARY:
  Specifically, all GUI trees are not impacted.

  configure
  - added --cross=PREFIX
  - reworked search for gcc and cross-compile related tools to use prefix

  contrib/
  - sub-patches added as needed for mingw

  contrib/xvidcore/
  - bumped from 1.1.3 -> 1.2.1+ (daily 20090311)
  - reconstituted P01-cygwin.patch
  - created new P00-darwin.patch needed for macho64 asm flag on x86_64 arch
  
  libhb/
  - uint -> uint32_t
  - remaining changes guarded by mingw32 macro.
  
  test/
  - modified to support pthread-compatibility library attach/detach.
  - all changes guarded by mingw32 macro.
