Lightweight Java Game Library Code

Linux: Removed the glXIsDirect test to determine whether a context is accelerated or not. This is specifically not the case for Xgl and friends that accelerates indireect rendering. Unfortunately, I'm not sure what to replace the test with, so there is currently no way to know from LWJGL whether we're software rendered or not (other than measuring FPS). In fact, I'm not even sure that we can come up with a good test, because some (DRI) drivers use software MESA rendering for some parts of GL, while other parts are hardware accelerated

Linux: Fixed resetDisplayMode in case XRandr is used and the first reported mode is not the initial mode

OpenAL: Split platform dependent code from extal.c into platform subdirs. Made nCreate take a path instead of an array of paths.

Linux: Made Xxf86vm dynamically linked when compiling to amd64

Linux: don't throw exception if Xrandr or XF86VM extension query fails

Linux: Re-added RTLD_GLOBAL to dlopen() with a comment since DRI drivers need it.

Added setSwapInterval to Display and AWTGLCanvas

Linux: Added lwjgl.map to specify symbol visibility. Only Java_ symbols will be exported from the liblwjgl.so library now

Linux: Removed the unnecessary RTLD_GLOBAL flag from the dynamic loading of libGL.so
