when extending the driver interface. The card and accel structures are
merged into the ExaDriverRec, which is to be allocated using
exaDriverAlloc(). The driver structure also grows exa_major and
exa_minor, which drivers fill in and have checked by EXA
(double-checking that the driver really did check that the EXA version
was correct). Removes exaInitCard(), which is replaced by the driver
filling in the rec by hand, and the exaGetVersion() and related
EXA_*VERSION which are replaced by always using the XFree86 loadable
module versioning.
