updated and added license where needed

Linux: Fixed fetch of a boolean field with GetIntField JNI

Windows implementation of floating point pixel formats

Added floating point format to PixelFormat. Linux implementation

Linux: Apparently, some the Mesa GLX 1.3 glxChooseFBConfig don't like the GLX_STEREO attribute, even when set to False. So we'll only specify GLX_STEREO in case a stereo context is actually requested

Linux: Fixed accum color bits when accum_bpp = 0

Linux: renamed _glX* function pointers to lwjgl_glX* to avoid symbol clash problems discovered in mustang

Linux: Added missing NULL check

Linux: Handle different GLX capabilities on different screens
