Fixed building using MinGW
Our SDL_windows.h needed to be included before anything else so UNICODE is defined.
Removed redundant #ifdef
Fixed 1598 - Mingwin build fails on src/audio/xaudio2/SDL_xaudio2.c
Fixed bug 2069 - Device addition/removal queries all USB devices rather than only HID devices.

Andreas Ertelt
SDL_dxjoystick.c is setting the classguid for device (dis)connect events to USB Devices in general:
    dbh.dbcc_classguid = GUID_DEVINTERFACE_USB_DEVICE;

Wouldn't it make more sense to have it just subscribe to Hid device events? This would mean less meaningless events reaching the application.
Fixed bug 2155 - automatically remap accelerometer coordinates according to screen orientation on Android

Background information: http://android-developers.blogspot.fr/2010/09/one-screen-turn-deserves-another.html and http://developer.android.com/reference/android/hardware/SensorEvent.html

Right now, the Android accelerometer event handler feeds raw accelerometer data  to the SDL Joystick driver. The result is that for landscape-only applications, the axis need to be swapped if running on a portrait device (like a phone), and vice-versa: running a portrait only app on a landscape device like a tablet.

The purpose of this patch is to perform coordinate remapping of the accelerometer data before feeding it to the SDL joystick driver so that the X axis of the joystick is always aligned with the X axis of the display, same for the Y axis.

This has been tested on applications that support screen orientation changes as well as applications with fixed screen orientations, both on phones and tablets.
