Use __DRIextension mechanism providing loader functionality to the driver.

Instead of passing in a fixed struct, the loader now passes in a list
of __DRIextension structs, to advertise the functionality it can provide
to the driver.  Each extension is individually versioned and can be
extended or phased out as the interface develops.
