Allow osmesa to be enabled or disabled
The conditional in src/mesa/Makefile currently hardcodes the cases where libOSMesa can be built on libGL. Likewise, the xlib case always includes libOSMesa in the stand-alone target. This changes the conditional to a loop over the DRIVER_DIRS variable. This means that any driver configuration can enable or disable osmesa. The current "stand-alone" rule is changed so that DRIVER_DIRS=x11 and DRIVER_DIRS="x11 osmesa" are both respected. The configure option is changed to --enable-gl-osmesa as this change allows libOSMesa to be built upon any of the libGL-enabling drivers.
