Add Android NDK module definition + sample application

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.

+This is a sample Android executable that can be used to test the
+Google Breakpad client library on Android.
+
+Its purpose is simply to crash and generate a minidump under /data/local/tmp.
+
+Build instructions:
+
+   cd android/sample_app
+   $NDK/ndk-build
+
+  Where $NDK points to a valid Android NDK installation.
+
+Usage instructions:
+
+   After buildind the test program, send it to a device, then run it as
+   the shell UID:
+
+     adb push libs/armeabi/test_google_breakpad /data/local/tmp
+     adb shell /data/local/tmp/test_google_breakpad
+
+   This will simply crash after dumping the name of the generated minidump
+   file.
+
+   See jni/test_breakpad.cpp for details.
+
+   Use 'armeabi-v7a' instead of 'armeabi' above to test the ARMv7-A version
+   of the binary.
+
+Note:
+   If you plan to use the library in a regular Android application, store
+   the minidump files either to your app-specific directory, or to the SDCard
+   (the latter requiring a specific permission).
