A grab mask provided in the request may be larger than the one used in the
server. Cut down to size before memcopying.

Fixes crash if the first XISelectEvents has a zero sized event mask.

masks can be of arbitrary length. If the client did not initialize mask_len,
some sort of boundary check is needed to avoid running over memory.

Leave consoleFd open over the course of the server, even though any use
of it in this context is likely to be disastrous.

Note that the Xi events are critical and should thus cause a flush to
the client when an input event is pending.

A missing break meant that ButtonPress would fall through into
ButtonRelease, but luckily it appears to have been completely harmless.

xf86SlowBCopyToBus and xf86SlowBCopyFromBus cause segfaults on my
system.
Also remove associated slowbcopy_tobus/slowbcopy_frombus macros.

BUSmemcpy.c provides xf86BusToMem and xf86MemToBus, which are are memcpy
wrappers written to avoid glibc's memcpy on Alpha. glibc'c memcpy on
Alpha has improved much since this was written, so it's no longer
needed. Neither function is used inside the xserver, and no module on
my machine uses either as well.

All architectures should be able to use the same unaligned access code,
regardless of whether they need special unaligned access instructions.
Let's let gcc do the heavy lifting.
In the case that we're not using a gcc-compatible compiler, use memmove.
The xserver already requires pixman, so include pixman.h for its uint*_t
types.

Checks for __GNUC__ are superfluous since the only other compiler for
the platform is Compaq C, and it doesn't support GCC style inline
assembly.

Referencing a screen through a drawable only requires GetAttr access.
Treat dri2 drawables as child windows (Add/Remove access).
Treat getting buffers as intent to read/write the drawable.

The spec says x870, but we actually use x864 because that's a real DMT
mode and x870 isn't. This might or might not be wrong, but we should at
least tell the truth.
- unused return value
- no reason to declare static variable given the function is just called
once
- no reason to declare different type and cast it after.

This adds support for using the libpciaccess interface for
vga arbitration support on top of a kernel which supports it.
Currently patches are queued for kernel 2.6.32 in jbarnes
pci tree, and shipping in Fedora kernel.

This patch corrects a misnaming of XTest-related functions.
The extension itself announces itself as XTEST. Xtst is the library name
itself, but all library functions are prefixed by XTest. Same with the
naming in the server.
- Rename all *Xtst* functions to *XTest* for consistency with the library
and in-server API.
- Rename the "Xtst device" property to "XTEST device" for consistency with
the extension naming.
- Rename the device naming to "<master device name> XTEST device". The
default xtest devices become "Virtual core XTEST pointer" and "Virtual
core XTEST keyboard".
