[PATCH 0/9] per-device idle counters

[Peter Hutterer]

We currently have one global idlecounter. This patch series adds additional
counters named "DEVICEIDLETIME n" (where n is the device id) that apply to
that device only. 

One use-case here is as syndaemon replacement. A client can simply put an
idlecounter on the keyboard above the touchpad. When that keyboard goes out
of idle, disable the touchpad, then re-enable when the keyboard goes idle
again.

Cheers,
  Peter
