Fixes a build breakage when $(top_srcdir) != $(top_builddir) because
-I$(top_srcdir)/include is missing for the cvt, ioport, pcitweak, and scanpci
builds.

This also removes static from some other functions that had been copied out
to at least the intel driver, but perhaps others that were doing mode list
handling.
As discussed on the mailing list, people would rather have an X command-line
option to print the module path so installers can know where to put modules,
rather than the installers using `pkg-config --variable=moduledir xorg-server`,
since some distros choose not to install xorg-server.pc.
xf86 drivers need to create RandR object in the PreInit stage,
before the ScreenRec is allocated. Changing the RandR DIX code
to permit this required the addition of functions that later associate the
objects with the related screen.
An additional change is that modes are now global, and no longer associated
with a specific screen. This change actually makes mode management cleaner
as there is no more per-screen list of modes to deal with.
This changes the RandR 1.2 ABI/API for drivers.
Only try to build Linux support on Linux. We should probably disable all
OS-dependent DDXes if we don't have a workable OS (and only build
Xephyr/Xfake), but that's future work.
If we're mapping something in the "legacy range" (0-1Mb), we shouldn't
expand the requested range to the entire 0-1Mb range. Typically this
is for mapping the VGA frame buffer, and some platforms support mmap of
the frame buffer but not the entire 0-1Mb range.
For example, HP sx1000 and sx2000 ia64 platforms can have memory from
0-0x9ffff, VGA frame buffer from 0xa0000-0xbffff, and memory from
0xc0000-0xfffff. On these platforms, we can't map the entire 0-1Mb
range with the same attribute because the memory only supports WB,
while the frame buffer supports only UC. But an mmap of just the
frame buffer should work fine.
Mach64 driver bails out on ia64 because it cannot map device
memory. It turns out that some bogus and unneeded code attempts
to find the root bridge of the device and fails to do so proberly
as there this host-to-pci bridge is not existant. This code has
been around for years although it completely unclear what it had
been intended for. Fixing this by eliminating the bogus code.
