Back when we had RAC this was a vaguely meaningful thing. Since then
it's been a glorified (and confusing) wrapper around xf86BlockSIGIO.
Note that the APM and VT switch code are unusual relative to other code
that cares about SIGIO state. Most callers push a SIGIO disable to
create a critical section for the duration of the caller's stack frame,
but those two effectively disable SIGIO after their return and re-enable
on their next entry.

This struct is superfluous, maintaining the same info as the InputInfoRec
(with the exception of the driver name).
This is a rather large commit with the majority of changes being a rename
from the fields of the IDevRec (idev, commonOptions) to the InputInfoRec
(pInfo, options).
The actual changes affect the initialization process of the input device:
In NewInputDeviceRequest, the InputInfoRec is now always allocated and just
added to the internal list in xf86NewInputDevice() if the init process
succeeded.

All functions that touch PCI and BUS were moved to their own files, organizing
the mess inside the InitOutput. Now, inside InitOutput, mostly accesses to
buses are coordinated by the new xf86BusConfig.

isolate devices parameters was created also, named xf86PciIsolateDevice.

The function was only initializing the boolean xf86ResAccessEnter, which
couldn't get any other value in the life of the server.
The only possible, though suspicious, code was in xf86AccessLeave(), which
could be triggered if AbortDDX is called before xf86AccessInit(). Even so,
such change is safety because no driver would have configured any entity leave
procedure at this point.

The problem fixed by this patch can be reproduced on Linux with the
following steps.
- Access NULL pointer intentionally in ProcessOtherEvent on key press.
- Instead of saving core dump to a file, write it into a pipe.
echo "|/usr/sbin/my-core-dumper" > /proc/sys/kernel/core_pattern
- Dump the core by pressing a key.
While the core is being dumped into the pipe, the smart schedule timer
will cause a pending SIGALRM. Linux kernel stops writing data to the
pipe when there are pending signals. This causes the core dump to be
truncated. On my system I'm expecting a 6 MB dump but the size will be
60 kB instead. The problem is solved if we block the SIGALRM caused by
expired smart schedule timer.
I haven't been able to reproduce this problem in the following cases.
- Save core dump to a file instead of a pipe.
- kill -SEGV `pidof Xorg`
- Press a key to dump core while gdb is attached to Xorg.
- Give option -dumbSched to Xorg.
Also note that the fix works only when NoTrapSignals has the default
value FALSE. The problem can still be reproduced if error signals
aren't trapped. In addition to pending SIGALRM, there is a similar
problem with pending SIGIO from the keyboard driver during core dump.

xextproto had Xlib client headers moved into libXext.
Protocol header files are named fooproto.h, header files with constants
foo.h or fooconst.h where foo.h was already in use for client-side headers.
Otherwise no subsequent driver will be able to claim this pci slot.
Example for this: fbdev tries to claim, but framebuffer device is not
available. Later on VESA cannot claim the device.
A grep on xorg/* revealed there's no consumer of this define.
Quote Alan Coopersmith:
"The consumer was in past versions of the headers now located
in proto/x11proto - for instance, in X11R6.0's xc/include/Xproto.h,
all the event definitions were only available if NEED_EVENTS were
defined, and all the reply definitions required NEED_REPLIES.
Looks like Xproto.h dropped them by X11R6.3, which didn't have
the #ifdef's anymore, so these are truly ancient now."

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).
