Input driver messages are only standardised by convention, with the drivers
prefixing the device name to most messages. This makes it rather hard to
grep on "evdev" for example when looking for the evdev ouput.
This patch adds three new logging functions, modeled after xf86DrvMsg(), the
logging function for output drivers. New functions are
xf86IDrvMsg() - input driver log message in default verbosity.
xf86IDrvMsgVerb() - input driver log message in specified verbosity.
xf86VIDrvMsgVerb() - same as xf86IDrvMsgVerb() but takes a varargs
argument.
Default log format is <driver name>: <device name>: <message>.
