This patch adds a new directory named "android/" which contains
the following:

- A NDK build system module definition for the Google Breakpad
  client library. This can be used by developers using the ndk-build
  build system to more easily build and use the client library in
  their own programs.

- A sample application demonstrating how to use the module,
  as well as test that the library works properly during a
  crash.

- A shell script (run-checks.sh) that will check everything
  for you automatically, including:

  - Rebuilding the host Google Breakpad host package with configure/make
  - Rebuilding the Android client library with configure/make
  - Rebuilding the Android client library and test program with ndk-build
  - Running the crashing test program, extract minidump, dump symbols,
    generate a stack trace and check that it has correct source file
    locations.

For more details, run android/run-checks.sh --help-all

+ Updates to the README.ANDROID documentation.
