gallium/noop: no operation gallium driver
This driver is a fake swdri driver that perform no operations
beside allocation gallium structure and buffer for upper layer
usage.
It's purpose is to help profiling core mesa/gallium without
having pipe driver overhead hidding hot spot of core code.
scons file are likely inadequate i am unfamiliar with this
build system.
To use it simply rename is to swrast_dri.so and properly set
LIBGL_DRIVERS_PATH env variable.
