moused(8): Add support for evdev protocol
The new daemon have following properties as compared with previous
incarnation:
- evdev protocol support for mices and touchpads. Additionally to relative PS/2 and USB devices it enables console support for I2C/USB touchpads and bluetooth mices.
- Other aged protocols like COM, raw PS/2 and X10 are dropped with only exception of sysmouse. For those who still use them there is an utility called msconvd(8).
- single daemon per system where hotplug is processed via devd socket. Per device mode still supported too.
- Configuration and quirks files in libinput-compatible format. Actually, the new moused config parser is taken from libinput.
The moused(8) can work in 2 modes:
- Evdev support mode. It enables all previously mentioned devices. It is enabled by deault.
- Sysmouse support mode. All should work as before. No new devices supported. To enable it add following lines to /etc/rc.conf: moused_port="/dev/psm0" moused_nondefault_enable="YES" One may add hw.usb.usbhid.enable=0 to /boot/loader.conf to enable ums(4) driver which supports sysmouse protocol.
