[Qemu-devel] Make thread pool implementation modular

[Matthias Brugger]

This patch series makes the thread pool implementation modular.
This allows each drive to use a special implementation.
The patch series prepares qemu to be able to include thread pools different
the one actually implemented. It will allow to implement approaches like 
paravirtualized block requests [1].
