These patches provide the qmp interface, to query the io throttle status of the all fsdev devices that are present in a vm. also, it provides an interface to set the io throttle parameters of a fsdev to a required value. some of the patches also remove the duplicate code that was present in block and fsdev files.

As per the suggestion I split the patches into smaller patches. Removed some more duplicate code. v2 -> v3: Addressed the comments from Alberto Garcia. Changed the comment from block to iothrottle in the iothrottle.json Added the dummy functions in qemu-fsdev-dummy.c to address the compilation issues that were observed. -- 1.8.3.1
