touchpad: add a tool to measure the touchpad fuzz
Well, I say "measure" but really at this point it just reads the properties/axes and then does it's best to auto-generate a hwdb entry that matches the user's hardware and sets a fuzz value on the device. Ideally this reduces the number of hand-holding required in bugzillas. There are plenty of things that can go wrong, so our fallback is still to throw up our hands and point to the documentation. https://bugs.freedesktop.org/show_bug.cgi?id=98839 Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>

+.SH NAME
+libinput\-measure\-fuzz \- measure absolute axis fuzz
+.SH SYNOPSIS
+.B libinput measure fuzz [\-\-help] [options]
+[\fI/dev/input/event0\fI]
+.SH DESCRIPTION
+.PP
+The
+.B "libinput measure fuzz"
+tool measures the fuzz for an absolute axis on a kernel device. The current
+implementation does not actually measure anything, it only prints the
+relevant information available and suggests a udev rule.
+.PP
+This is a debugging tool only, its output may change at any time. Do not
+rely on the output.
+.PP
+This tool usually needs to be run as root to have access to the
+/dev/input/eventX nodes.
+.SH OPTIONS
+If a device node is given, this tool opens that device node. Otherwise, this
+tool searches for the first node that looks like a touchpad device and
+uses that node.
