This patch allows the definition which thread pool will be used by
every block device. The defintion of the workerthreads option
allows this at the command line level.
At the moment only the thread pool implementation "pool" can be chosen.

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 request
