Switch man pages to asciidoc.
The docbook xml is unreadable and unwritable. Switch everything to asciidoc, at least thay we we can write man pages without losing sanity. asciidoc seems to have some issues with __libmansuffix__, so instead we just use libmansuffix (without underscores). The current asciidoc version is buggy for multiple man targets (more than one man page in a single file), so stick a big warning into configure that a patch is required to the the right asciidoc->docbook conversion. Many thanks to Dan Nicholson for the Makefile.am. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>

+XOPENDEVICE(libmansuffix)
+=========================
+
+NAME
+----
+
+ XOpenDevice, XCloseDevice - open or close an extension input
+ device
+
+SYNOPSIS
+--------
+
+ #include <X11/extensions/XInput.h>
+
+ XDevice *XOpenDevice( Display *display,
+ XID device_id);
+
+ XCloseDevice( Display *display,
+ XDevice *device);
+
+ display
+ Specifies the connection to the X server.
+
+ device_id
+ Specifies the id of the device to be opened
+
+ device
+ Specifies the device to be closed
+
+DESCRIPTION
+-----------
+
+ The XOpenDevice request makes an input device accessible to a
+ client through input extension protocol requests. If
+ successful, it returns a pointer to an XDevice structure.
+
+ The XCloseDevice request makes an input device inaccessible to
+ a client through input extension protocol requests. Before
+ terminating, and client that has opened input devices through
+ the input extension should close them via CloseDevice.
+
+ When a client makes an XCloseDevice request, any active grabs
+ that the client has on the device are released. Any event
+ selections that the client has are deleted, as well as any
+ passive grabs. If the requesting client is the last client
+ accessing the device, the server may disable all access by X to
+ the device.
+
+ XOpenDevice and XCloseDevice can generate a BadDevice error.
+
+Structures
+
+ The XDevice structure returned by XOpenDevice contains:
+ typedef struct {
+ XID device_id;
+ int num_classes;
+ XInputClassInfo *classes;
+ } XDevice;
+
+ The classes field is a pointer to an array of XInputClassInfo
+ structures. Each element of this array contains an event type
+ base for a class of input supported by the specified device.
+ The num_classes field indicates the number of elements in the
+ classes array.
+
+ The XInputClassInfo structure contains:
+
+ typedef struct {
+ unsigned char input_class;
+ unsigned char event_type_base;
+ } XInputClassInfo;
+
+ The input_class field identifies one class of input supported
+ by the device. Defined types include KeyClass, ButtonClass,
+ ValuatorClass, ProximityClass, FeedbackClass, FocusClass, and
+ OtherClass. The event_type_base identifies the event type of
+ the first event in that class.
+
+ The information contained in the XInputClassInfo structure is
+ used by macros to obtain the event classes that clients use in
+ making XSelectExtensionEvent requests. Currently defined macros
+ include DeviceKeyPress, DeviceKeyRelease, DeviceButtonPress,
+ DeviceButtonRelese, DeviceMotionNotify, DeviceFocusIn,
+ DeviceFocusOut, ProximityIn, ProximityOut, DeviceStateNotify,
+ DeviceMappingNotify, ChangeDeviceNotify,
+ DevicePointerMotionHint, DeviceButton1Motion,
+ DeviceButton2Motion, DeviceButton3Motion, DeviceButton4Motion,
+ DeviceButton5Motion, DeviceButtonMotion, DeviceOwnerGrabButton,
+ DeviceButtonPressGrab, and NoExtensionEvent.
+
+ To obtain the proper event class for a particular device, one
+ of the above macros is invoked using the XDevice structure for
+ that device. For example,
+ DeviceKeyPress (*device, type, eventclass);
+
+ returns the DeviceKeyPress event type and the eventclass for
+ DeviceKeyPress events from the specified device.
+
+ This eventclass can then be used in an XSelectExtensionEvent
+ request to ask the server to send DeviceKeyPress events from
+ this device. When a selected event is received via XNextEvent,
+ the type can be used for comparison with the type in the event.
+
+DIAGNOSTICS
+-----------
+
+ BadDevice
+ An invalid device was specified. The specified device
+ does not exist, or is the X keyboard or X pointer. This
+ error may also occur if some other client has caused the
+ specified device to become the X keyboard or X pointer
+ device via the XChangeKeyboardDevice or
+ XChangePointerDevice requests.
