This hook wasn't used by any DDX. Device addition and removal is handled by

Peter Hutterer cb672a461c input: remove OpenInputDevice and CloseInputDevice DDX hooks.
In theory, these hooks were to be used for DDX-specific device enablement.
None of the DDXs however did anything here. Now we call DEVICE_INIT on all
devices when they are added, so the xfree86 DDX as the only one with real
code didn't do anything here.

kdrive checked for device validity but that's already handled in
ProcXOpenDevice.

Peter Hutterer 8764782f6d xfree86: add xf86IDrvMsg and friends for input driver logging.
Input driver messages are only standardised by convention, with the drivers
prefixing the device name to most messages. This makes it rather hard to
grep on "evdev" for example when looking for the evdev ouput.

This patch adds three new logging functions, modeled after xf86DrvMsg(), the
logging function for output drivers. New functions are
   xf86IDrvMsg()        - input driver log message in default verbosity.
   xf86IDrvMsgVerb()    - input driver log message in specified verbosity.
   xf86VIDrvMsgVerb()   - same as xf86IDrvMsgVerb() but takes a varargs
                          argument.

Default log format is <driver name>: <device name>: <message>.

The main change introduced in this patch is the removal of the
back-and-forth between DDX and the driver.
The DDX now allocates the InputInfoRec and fills it with default values. The
DDX processes common options (and module-specific default options, if
appropriate) before passing the initialised struct to the driver.

The driver may do module-specific initializations and return Success or an
error code in the case of a failure.

Dan Nicholson a71bdff47d xfree86: Allow multiple InputClass Match* entries for && matching
Currently when there multiple InputClass entries of the same type, only
the last entry is used and the previous ones are ignored. Instead,
multiple entries are used to create multiple matching conditions.

For instance, an InputClass with

	MatchProduct "foo"
	MatchProduct "bar"

will require that the device's product name contain both foo and bar.
This provides a complement to the || style matching when an entry is
split using the "|" token.

The xorg.conf man page has added an example to hopefully clarify the two
types of compound matches.

Keith Packard 2dc138922b Rename region macros to eliminate screen argument
This is a combination of a huge mechanical patch and a few small
fixups required to finish the job. They were reviewed separately, but
because the server does not build without both pieces, I've merged
them together at this time.

The mechanical changes were performed by running the included
'fix-region' script over the whole tree:

$ git ls-files | grep -v '^fix-' | xargs ./fix-region

And then, the white space errors in the resulting patch were fixed
using the provided fix-patch-whitespace script.

$ sh ./fix-patch-whitespace

Thanks to Jamey Sharp for the mighty fine sed-generating sed script.

The hand-done changes involve removing functions from dix/region.c
that duplicate inline functions in include/regionstr.h, along with
their declarations in regionstr.h, mi.h and mispans.h.

Peter Hutterer 531ff40301 Add a "flags" field to DeleteInputDeviceRequest.
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.

Peter Hutterer c2d0b3b437 xfree86: store the InputAttributes in the input device.
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.
