[QUARTZDRV] Preliminary support for native OS X graphics

[Rib Rdb]

This patch includes a partially graphics driver for OS X.  Everything
except the basic window management functions of the user driver are
stubs.  The patch depends on Pierre d'Herbemont's "Support for
disabling symbols import in WineBuild based on a prefix."

Changelog:
    Rib Rdb <ribrdb at gmail.com>
    Add preliminary support for native graphics on Mac OS X.
