Support for multiple usermaps in hotplug usb.agent

["Maksim (Max) Krasnyanskiy" <maxk@qualcomm.com>]

Hi Ukai,

We were discussing my proposal to introduce support for multiple usermaps 
in usb.agent
on linux-hotplug-devel mailing list. David Brownell had a concern that my 
solution
is different from Debian and therefor may introduce some problems.
So I'd like to get your opinion, as a Debian hotplug maintainer, on that.

Here is my patch for hotplug 2002.04.01

Basically the idea is simple. Packages/subsystems simply install their own 
XXX.usermap
into /etc/hotplug/usb. And usb.agent processes them in addition to original
usb.usermap.
It seems to be simpler than what Debian does right now. ie generating new 
usb.usermap
whenever something gets installed or uninstalled.
