This bumps the build SDK level to 12 (up from 10). Runtime requirements remain
the same (at API level < 12 joystick support is disabled).
Also enables building SDL for armv7 and x86.

This patch to Android.mk adds support for static linking of libSDL for Android applications. A patched readme with static build instructions is also provided.
It does not break existing build environments setup according to the README-android.txt since the static library version will not be built in not required.
The static build uses the Android NDK module system (see docs/IMPORT-MODULE.html in the NDK folder and step 5 in the instructions below).
Instructions:
1. Copy the android-project directory wherever you want to keep your projects
and rename it to the name of your project.
2. Create a symlink to SDL/src/main/android/SDL_android_main.c as
<project>/jni/src/SDL_android_main.c
3. Rename <project>/jni/src/Android_static.mk to <project>/jni/src/Android.mk
(overwrite the existing one)
4. Edit <project>/jni/src/Android.mk to include your source files
5. create and export an environment variable named NDK_MODULE_PATH that points
to the parent directory of this SDL directory. e.g.:
export NDK_MODULE_PATH="$PWD"/..
6. Edit <project>/src/org/libsdl/app/SDLActivity.java and remove the call to
System.loadLibrary("SDL2") line 42.
7. Run 'ndk-build' (a script provided by the NDK). This compiles the C source
Although this requires an environment variable to be setup, it can be added once and for all to the main Android.mk of the project.
C++ is a bit of a minefield on Android. Much functionality still doesn't work, and Android can't decide on which C++ standard library to use, so it provides 3 different ones, all of which are incompatible with each other. (It looks like clang is coming too which will add a new compiler and a 4th standard library.)
As middleware, SDL might be distributed as a binary and intermixed with other projects already using C++. If C++ is intermixed in a bad way, bad things will happen. Removing dependencies on C++ will avoid this problem and downstream users won't have to worry/care.

rename : src/core/android/SDL_android.cpp => src/core/android/SDL_android.c
rename : src/main/android/SDL_android_main.cpp => src/main/android/SDL_android_main.c
Added information on how to customize your application name and icon.
Added information on using STL with an Android application
Increased the minimum API level to 10, because that's the lowest API
that currently has an emulator image for testing.
