/*
 * SupportedInterfaces: Returns the mouse interface types that the OS support.
 *		If MSE_MISC is returned, then the BuiltinNames and
 *		CheckProtocol should be set.
 *
 * BuiltinNames: Returns the names of the protocols that are fully handled
 *		in the OS-specific code.  These are names that don't appear
 *		directly in the main "mouse" driver.
 *
 * CheckProtocol: Checks if the protocol name given is supported by the
 *		OS.  It should return TRUE for both "builtin" protocols and
 *		protocols of type MSE_MISC that are supported by the OS.
 *
 * PreInit:	The PreInit function for protocols that are builtin.  This
 *		function is passed the protocol name.
 *
 * DefaultProtocol: Returns the name of a default protocol that should be used
 *		for the OS when none has been supplied in the config file.
 *		This should only be set when there is a reasonable default.
 *
 * SetupAuto:	This function can be used to do OS-specific protocol
 *		auto-detection.  It returns the name of the detected protocol,
 *		or NULL when detection fails.  It may also adjust one or more
 *		of the "protoPara" values for the detected protocol by setting
 *		then to something other than -1.  SetupAuto gets called in two
 *		ways.  The first is before any devices have been opened.  This
 *		can be used when the protocol "Auto" always maps to a single
 *		protocol type.  The second is with the device open, allowing
 *		OS-specific probing to be done.
 *
 * SetPS2Res:	Set the resolution and sample rate for MSE_PS2 and MSE_XPS2
 *		protocol types.
 *
 * SetBMRes:	Set the resolution and sample rate for MSE_BM protocol types.
 *
 * SetMiscRes:	Set the resolution and sample rate for MSE_MISC protocol types.
 *
 * FindDevice:	This function gets called when no Device has been specified
 *		in the config file.  OS-specific methods may be used to guess
 * 		which input device to use.  This function is called after the
 *		pre-open attempts at protocol discovery are done, but before
 * 		the device is open.  I.e., after the first SetupAuto() call,
 *		after the DefaultProtocol() call, but before the PreInit()
 *		call.  Available protocol information may be used in locating
 *		the default input device.
 *
 * GuessProtocol: A last resort attempt at guessing the mouse protocol by
 *		whatever OS-specific means might be available.  OS-independent
 *		things should be in the mouse driver.  This function gets
 *		called after the mouse driver's OS-independent methods have
 *		failed.
