Convert op->drive_g from a 16bit pointer to a 32 bit "GLOBALFLAT" pointer.

The "drive" structure is always malloc'ed and therefore always starts
off described as a 32-bit "flat" pointer.  Instead of switching
to/from 16bit pointers, make all the code use the 32bit pointer.  This
eliminates the confusing 16/32 bit pointer switches.

This patch also removes the "_g" suffixes on local variables in
functions that are always called in 32bit mode.
