This moves most of the cursor management code out of the intel driver and
into the general server code. Of course, the hope is that this code will be
useful for other driver writers as well.
Check out xf86Crtc.h for the usage information, making sure you add the
needed hooks to the crtc funcs structure for your driver.
(cherry picked from commit 4d81c99a46)
Code added in hw/xfree86/modes came from the server-1.3-branch.
Portions of this code had previously been integrated into xf86Mode.c
and edid_modes.c.
To preserve hw/xfree86/modes as much as possible, the duplicate code from
the other files has been disabled; a more careful review would figure out
where that code actually belonged.
This code comes from the intel driver, so there's no history in this tree.
As the crtc/output-based mode selection code uses ddc, the ddc and i2c
modules have been merged into the server. Attempts to load them are safely
ignored now.
