PATCH 1/17 REV 2 USB virt 2.6 split driver---xenidc platform

This patch implements some platform facilities used by the xenidc transport which is in turn used by the USB driver:

o - A callback object for asynchronous completion of requests submitted to services.
o - A work item object for scheduling tasks which builds on the native linux work queues.
o - Some simple trace macros for the xenidc code.
o - An error type which is supposed to be platform independent.
