Disable GrabEventDevice by default
This was required when we started supporting hotplugging to avoid duplicate
events. These days the drawback of not being able to record events in the case
of a bug is significant.
Check the configuration source on init. If the device was hotplugged through a
a server config backend, disable the grab. If the device was statically
configured through an xorg.conf then leave the default grab enabled to avoid
a duplicate device.
