android: Add Android support

Add Android support for Waffle. This uses Android.mk files for compiling.
By default the compilation is for Jelly Bean, adding defintion for
BUILD_FOR_ICS will be able to compile for Ice Cream Sandwitch.

[chadv]: Changes from Juha-Pekka's original patch:

  - Update with changes to build system.
    - Add 'include/waffle' to Android.mk:LOCAL_C_INCLUDES. A parallel
      change has occured in the CMake build on master.
    - Generate waffle_version.h at buildtime, just as CMake does.

  - Fix namespace and prefix issues.
    - File android_surface_surfaceflingerlink.cpp added symbols to the C++
      namespace 'android', but that namespace is owned by the Android
      platform. So I renamed the namespace to 'waffle'.
    - All files added C symbols prefixed with 'android', but that prefix
      is also owned by the Android platform. So I changed the prefix of
      all such symbols to 'droid'. Accordingly, I renamed all files from
      'android_$stuff.[ch]' to 'droid_$stuff.[ch]' to match the naming
      convention followed by other directories.
