asynchronous task offloading framework (called threadlets)
within qemu.

Make paio subsystem use threadlets infrastructure
From: Aneesh Kumar K.V aneesh.ku...@linux.vnet.ibm.com
This patch creates a generic asynchronous-task-offloading infrastructure named
threadlets.
The patch creates a global queue
a subsystem to create a private queue
with an associated pool of threads.
The patch has been tested with fstress.

This patch implements the second threading model.
The first model can be referred here:
http://www.mail-archive.com/qemu-devel@nongnu.org/msg43846.html
The features of the second threading model:

Currently it is a normal mutex, but I will change it into a rw mutex.
This should be held in read mode while looking up and in write mode
while updating the list.

In this model we hand over the vcpu thread only executes till
the first blocking operation. It then hands over the call to
the worker thread, which does everything needed to complete
the call. It can make multiple blocking calls. It finally
