It appears that Mono 3.4.0 fails to marshal SDL_JoystickGUID
correctly when used as a return value. Changing the fixed buffer
to a couple of long fields allows the struct to be marshalled
correctly.
On SDL, DPad inputs were not correctly translated from joystick
hat inputs.
Updated MappedGamePadDriver so that it will correctly recognize
combined joystick hat directions e.g. DPadLeft should be true when
DownLeft, Left, or UpLeft are returned from the joystick hat.
Sdl2InputDriver.Dispose() would call SDL_DelEventWatch with a different
"user_data" parameter than SDL_AdEventWatch. This caused the EventFilter
to remain registered and subsequently crash when closing and reopening a
window.
SDL_GL_GetCurrentContext will allow us to replace the weird
implementation in Sdl2Factory.CreateGetCurrentGraphicsContext()
and the latter to disable mouse emulation if we wish to.

SDL_GL_GetDrawableSize was introduced after 2.0.0, so we need to check for that version before we call this method. Fixes MethodNotFounException on vanilla libsdl2-2.0.0 on linux.
Git commit hashcodes are not compatible with the 16bit integer values found in .Net version numbers. Use the git commit count as a version number instead.
