Added the iOS port
Fixed render buffers not correctly resized on orientation changes
[iOS] Adjusted the code and build files to use Automatic Reference Counting
[iOS] Various adjustements to implementation
Added the Android port
Improved OpenGL error macro

It now supports functions that return values.
Improved OpenAL error macro

It now supports functions that return values.
Adapted the examples for iOS (WIP)
[iOS] Improved support for examples, removed the need for a toolchain file
[iOS] Removed the install rule of the deleted ios.cmake toolchain file
[iOS] Fixed linker command line in Graphics/CMakeLists.txt
Removed a copy of the sfml_add_example CMake macro, which was duplicated by accident in the big Android commit
[iOS] Made the build independent of the iOS framework version
Reworked the sfml-main module, added Main.hpp, moved the main() internal entry point for iOS from sfml-window to sfml-main
[iOS] Made the resources path the default working directory
[iOS] Removed support for examples, it was too much trouble and not as robust as true iOS App Xcode projects
[iOS] Added install rules to work around a CMake bug that prevented SFML libraries to be installed
[Android] Recompiled extlibs/ properly

External libraries are compiled with the latest NDK version (r9) with android-9 as API level using the recommended flags (see docs/).
External libraries are now compiled without the so version suffix because the NDK strips it at install time.
Static libraries of libsndfile and OpenAL-Soft have been removed because of their non-permissive license. It now uses their shared libraries.

NOTE: The audio module is disabled on MIPS arches because I was unable to compile OpenAL-Soft. Once the compilation issue fixed, I'll re-enable it.
[Android] Replaced our homemade Android CMake toolchain with the one used for the OpenCV project

[Android] Updated the Android CMake toolchain to support NDK r9

It brings support for 64-bits toolchains.
