mesa: implement DEBUG_ALWAYS_FLUSH debug option

Browse source 
This flag has been around for a while but it wasn't actually used anywhere.

Now, setting this flag causes a glFlush() to be issued after each
drawing call (including glBegin/End, glDrawElements, glDrawArrays,
glDrawPixels, glCopyPixels and glBitmap).
