Allow InputClass sections to match against the running operating system
to narrow the application of rules. An example where this could be used
is to specify that the default input driver on Linux is evdev while it's
mouse/kbd everywhere else.
The operating system name is the same as `uname -s`, and matching is
case-insensitive.

Peter wants to get a larger patch sequence put together and I didn't
read past the commit message to see the 'don't take this patch
please'.
This reverts commit 531ff40301.
Some input drivers need to implement an internal hotplugging scheme for
dependent devices to provide multiple X devices off one kernel device file.
Such dependent devices can be added with NewInputDeviceRequest() but they are
not removed when the config backend calls DeleteInputDeviceRequest(),
leaving the original device to clean up.
Example of the wacom driver:
config/udev calls NewInputDeviceRequest("stylus")
wacom PreInit calls
NewInputDeviceRequest("eraser")
NewInputDeviceRequest("pad")
NewInputDeviceRequest("cursor")
PreInit finishes.
When the device is removed, the config backend only calls
DeleteInputDeviceRequest for "stylus". The driver needs to call
DeleteInputDeviceRequest for the dependent devices eraser, pad and cursor to
clean up properly.
However, when the server terminates, DeleteInputDeviceRequest is called for
all devices - the driver must not remove the dependent devices to avoid
double-frees. There is no method for the driver to detect why a device is
being removed, leading to elaborate guesswork and some amount of wishful
thinking.
Though the input driver's UnInit already supports flags, they are unused.
This patch uses the flags to supply information where the
DeleteInputDeviceRequest request originates from, allowing a driver to
selectively call DeleteInputDeviceRequest when necessary.
Also bumps XINPUT ABI.

InputAttributes largely decide which configuration values get merged from
the xorg.conf.d snippets. While they are available in the config backend,
they are not available for any other callers of NewInputDeviceRequest().
Drivers implementing driver-side hotplugging do not have access to these
attributes and cannot have xorg.conf.d snippets specific to dependent
devices. For example, the following case cannot work right now:
Section "InputClass"
MatchProduct "Wacom"
Option "PressCurve" "0 0 100 100"
...
EndSection
Section "InputClass"
MatchProduct "Wacom"
MatchProduct "eraser"
Option "PressCurve" "10 10 50 50"
...
EndSection
The second section is not triggered, as the wacom driver cannot supply the
InputAttributes to NewInputDeviceRequest().
Add the attributes to the IDevRec and merge them into the InputInfoRec to
make them accessible in the driver. This changes the ABI for input drivers.

A driver that is assigned by an input class is only present as idev->driver.
The driver itself has no access to this information once PreInit is called.
For devices that rely on chain-hotplugging (wacom), this means that for the
second device the driver information is lost and the second device cannot be
initialized through NewInputDeviceRequest. Although this could be worked
around by hardcoding the driver name in the wacom driver, having the
assigned driver in the options seems like the better solution.
This issue only manifests itself with the udev backend. With HAL, the driver
is assigned by HAL and the option is duplicated in config/hal.c.

Currently the config and InputClasses are merged together so that the
options from the config backend have the highest priority. This is bad
since it means options such as a default XKB layout set by the backend
cannot be changed by the user.
This patch changes order of precedence to be:
1. xorg.conf
2. xorg.conf.d (later files have higher priority)
3. config backend
In order to allow this ordering, the config parsing has been changed to
read the xorg.conf.d files before xorg.conf. This has the consequence
that the core device picking which looks for the first InputDevice may
not find it in xorg.conf.

Tags may be a list of comma-separated strings that match against a MatchTag
InputClass section. If any of the tags specified for a device match against
the MatchTag of the section, this match is evaluated true and passed on to
the next match condition.
Tags are specified as "input.tags" (hal) or "ID_INPUT.tags" (udev), the
value of the tags is case-sensitive and require an exact match (not a
substring match).
i.e. "quirk" will not match "QUIRK", "need_quirk" or "quirk_needed".
Example configuration:
udev:
ENV{ID_INPUT.tags}="foo,bar"
hal:
<merge key="input.tags" type="string">foo,bar</merge>
xorg.conf:
Section "InputClass"
Identifier "foobar quirks"
MatchTag "foo|foobar"
Option "Foobar" "on"
EndSection
Where the xorg.conf section matches against any device with the tag "foo"
or tag "foobar" set.

Currently Xorg uses hal's fdi files to decide what configuration options
are applied to automatically added input devices. This is sub-optimal
since it requires users to use a new and different configuration store
than xorg.conf.
The InputClass section attempts to provide a system similar to hal where
configuration can be applied to all devices with certain attributes. For
now, devices can be matched to:
* A substring of the product name via a MatchProduct entry
* A substring of the vendir name via a MatchVendor entry
* A pathname pattern of the device file via a MatchDevicePath entry
* A device type via boolean entries for MatchIsKeyboard, MatchIsPointer,
MatchIsJoystick, MatchIsTablet, MatchIsTouchpad and MatchIsTouchscreen

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.
isMaster is not enough as long as we differ between master pointers and
keyboard. With flexible device classes, the usual checks for whether a
master device is a pointer (currently check for ->button, ->valuators or
->key) do not work as an SD may post an event through a master and mess this
check up.
Example, a device with valuators but no buttons would remove the button
class from the VCP and thus result in the
IsPointerDevice(inputInfo.pointer) == FALSE.
This will become worse in the future when new device classes are introduced
that aren't provided in the current system (e.g. a switch class).
This patch replaces isMaster with "type", one of SLAVE, MASTER_POINTER and
MASTER_KEYBOARD. All checks for dev->isMaster are replaced with an
IsMaster(dev).
This approach is broken anyway. DIPT only checked for the XInput type
"MOUSE" and the only user of this is xf86ActivateDevice when it sets the
Activate/DeactivateGrab functions.
Since synaptics and wacom set their own types, evdev only sets MOUSE for,
well, mice half the devices didn't have this set correctly anyway.
Instead, ActivatePointerGrab should be merged together with
ActivateKeyboardGrab.

DeleteInputDeviceRequest function doesn't handle "virtual" devices well.
TightVNC libvnc.so module to X (which makes bare Xorg VNC capable) uses such
kind of devices.
Bare Xvnc (it is something like Xvfb) simply uses AddInputDevice &
RegisterDevice functions. Xvnc uses DeleteInputDeviceRequest from Xi/stubs.c
so everything works fine (now I see that DeleteInputDeviceRequest in
Xi/stubs.c should call RemoveDevice function, shouldn't it? :) )
Situation is quite different when you use libvnc.so module. It uses same
schema as Xvnc, so it simply calls AddInputDevice & RegisterDevice. Thus
device is created correctly. When server is terminated it calls
DeleteInputDeviceRequest (now from hw/xfree86/common/xf86Xinput.c) for each
device. Here is the difference - Xvnc calls DeleteInputDeviceRequest from
Xi/stubs.c as I wrote above. Thus Xorg gets sigsegv because "VNC" devices
don't have real input driver.
