[RFC PATCH 0/1] allow system domains to allocate event channels

["Daniel P. Smith" <dpsmith@xxxxxxxxxxxxxxxxxxxx>]

In the discussion thread on patch `[PATCH v3 2/5] xen: make
evtchn_alloc_unbound public` there were a few suggestions on the appropriate
way to handle allowing the hypervisor to allocate event channels for domains
being constructed by dom0less and hyerplaunch. After taking another look at how
to generalize the suggested approach to temporarily promote the idle domain to
`is_privileged` it became clear there was a simpler and a longer term fix.

Since it was not discussed and with others are on limited time, I have not done
any testing beyond making sure this compiles and therefore I am sending this as
an RFC to allow everyone to review it. This also provides a patch should
dom0less would like to include it into their patch series.
