[Xen-devel] [PATCH OSSTEST v2] PDU/xenuse: Support xenuse on machine not locked by current user



xenuse checks that whoever is trying to reboot a machine "owns" that machine
via a locking mechanism. This is usually fine doesn't work well when one wants
to book a machine out of the osstest pool for adhoc testing. In this case
machine ownership is maintained by osstest ahd the machine remains locked to
osstest as far as xenuse is concerned.

Therefore add a global configuration option and perhost override to override
$USER (which xenuse obeys) to osstest.
---
v2: Use "local $ENV{USER}" which contrary to my previous experiments does
actually work.
