According to the spec, when SDL_SRCALPHA is set, the colorkey is ignored, so
we just need to convert the colorkey into the alpha channel.

Removed SDL_KillThread() from the API, as it isn't safe on many platforms.

One or two things got moved around, but largely this is hooked up correctly
in the Unix configure system now: it can be dynamically loaded and fallback
gracefully if not available, or libXi can be directly linked to libSDL.
XInput support can be --disable'd from the configure script, too (defaults to
enabled).
Please note that while the framework is in place to gracefully fallback, the
current state of the source requires XInput. We'll need to adjust a few
things still to correct this.

(The actual bug was in SDL code removed from the 1.3 codebase.)

Subject: Re: Updated DirectFB driver for SDL1.3
attached is a patch which brings the directfb driver in line with
current svn. In addition:
* driver now is in line with the structure of the X11 driver.
This adds a couple of files.
* driver now supports relative mouse movements
