When the smart scheduler is enabled, the VT ioctls (particularly
VT_WAITACTIVE) can be interrupted by the smart scheduler's SIGALRMs.
Previously, this caused the server to immediately continue on to
ScreenInit, almost certainly causing a crash or failure because the X
server that owned the VT hadn't finished cleaning up. As of commit
7ee965a300, it causes a FatalError
instead.
Retrying the ioctl as long as it fails with errno == EINTR fixes the
problem and allows server regenerations to trigger VT switches that
actually succeed.

Disable timer/keyboard trapping on GNU/Hurd for now
Trapping disabled for now, as some VBIOSes (mga-g450 notably) use these
ports, and the int10 wrapper is not emulating them.
It's effectively what happens in the Linux variant too, as iopl() is used there,
making the ioperm() meaningless.

This hook is only necessary for the keyboard driver to remove the race
condition between drain_console() and the driver's ReadInput (Bug 29969).
The idea is that a driver that needs to handle events from the console
calls xf86ReplaceConsoleHandler() with it's own ReadInput (or NULL) and thus
removes the drain_console call. It's the driver's responsibility to restore
the previous behaviour when the driver is unloaded.

The drain_console() function will race with new keyboard events being added
by the hardware causing the server to lose keyboard events if the console fd
is used for input.
Only use the drain_console() when AllowEmptyInput is off which is the best
indicator we have for whether the keyboard driver will be used. This patch
will only fix the bug when hotplugging is disabled.
What we really need is a way to figure out either whether we're _not_ using
the keyboard driver (not predictable) or a way for the keyboard driver to
disable drain_console().

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).
The warnings corrected were only the ones that should correct
real problems. The most common one is 64 bit integers as
"printf %l" arguments.
Note that there is a patch related to this at:
http://bugs.freedesktop.org/show_bug.cgi?id=18204
This is the biggest "visibility" patch. Instead of doing a "export"
symbol on demand, export everything in the sdk, so that if some module
fails due to an unresolved symbol, it is because it is using a symbol
not in the sdk.
Most exported symbols shouldn't really be made visible, neither
advertised in the sdk, as they are only used by a single shared object.
Symbols in the sdk (or referenced in sdk macros), but not defined
anywhere include:
