This is slightly draconian, but that API is just awful. In all but
one case in the callers it's used to get a map of some legacy VGA
memory, and it would be cleaner for the caller to just call
pci_device_map_legacy.
The sole exception is in the vesa driver, which uses it to avoid having
to look up which device the BAR belongs to. That's similarly trivial to
fix.
Having done that, Linux's PCI layer is now very small indeed.

Per-domain I/O is now something drivers must manually request, and must
keep track of within their own state rather than in the ScrnInfoRec.
It's not really possible to split that into two steps without an
additional intermediate ABI break, so don't even try. Drivers that want
source compatibility should ifdef on the presence of xf86UnmapLegacyIO.
As a fringe benefit, domain-aware I/O is now OS-independent, relying
only on support in pciaccess. Simplify OS PCI setup to reflect this.
The IOADDRESS type is kept around to help drivers through the API
transition and will be removed at some point in the future.

Save in a few special cases, _X_EXPORT should not be used in C source
files. Instead, it should be used in headers, and the proper C source
include that header. Some special cases are symbols that need to be
shared between modules, but not expected to be used by external drivers,
and symbols that are accessible via LoaderSymbol/dlopen.
This patch also adds conditionally some new sdk header files, depending
on extensions enabled. These files were added to match pattern for
other extensions/modules, that is, have the headers "deciding" symbol
visibility in the sdk. These headers are:
o Xext/panoramiXsrv.h, Xext/panoramiX.h
o fbpict.h (unconditionally)
o vidmodeproc.h
o mioverlay.h (unconditionally, used only by xaa)
o xfixes.h (unconditionally, symbols required by dri2)
LoaderSymbol and similar functions now don't have different prototypes,
in loaderProcs.h and xf86Module.h, so that both headers can be included,
without the need of defining IN_LOADER.
xf86NewInputDevice() device prototype readded to xf86Xinput.h, but
not exported (and with a comment about it).
xserver and libpciaccess both need to open /dev/xf86, which can only
be opened once. I implemented pci_system_init_dev_mem() like Ian
suggested. This requires some minor changes to the BSD-specific
os-support code. Since pci_system_init_dev_mem() is a no-op on
FreeBSD this should be no problem.
Note that pciaccess doesn't yet have Net/OpenBSD support, but the relevant
code should go there instead of disconnected code in the X Server.
While here, remove the now-disabled INCLUDE_XF86_NO_DOMAIN from the headers,
and un-disable xf8StdAccResFromOS for those OSes without domain support which
will need it.
