Subject[PATCH 00/18] introduce the Xen PV Calls backend
Hi all,

this series introduces the backend for the newly introduced PV Calls
procotol.

PV Calls is a paravirtualized protocol that allows the implementation of
a set of POSIX functions in a different domain. The PV Calls frontend
sends POSIX function calls to the backend, which implements them and
returns a value to the frontend and acts on the function call.

For more information about PV Calls, please read:

https://xenbits.xen.org/docs/unstable/misc/pvcalls.html

I tried to split the source code into small pieces to make it easier to
read and understand. Please review!
