nine: Add state tracker nine for Direct3D9 (v3)

Work of Joakim Sindholt (zhasha) and Christoph Bumiller (chrisbmr).
DRI3 port done by Axel Davy (mannerov).

v2: - nine_debug.c: klass extended from 32 chars to 96 (for sure) by glennk
    - Nine improvements by Axel Davy (which also fixed some wine tests)
    - by Emil Velikov:
     - convert to static/shared drivers
     - Sort and cleanup the includes
     - Use AM_CPPFLAGS for the defines
     - Add the linker garbage collector
     - Restrict the exported symbols (think llvm)

v3: - small nine fixes
    - build system improvements by Emil Velikov

v4: [Emil Velikov]
   - Do no link against libudev. No longer needed.
