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: Addresssed 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. v3 -> v4: Addressed comments from Eric Blake and Greg Kurz Re-ordered the patches Added the dummy functions in qmp.c to address the cross compilation issues v4 -> v5: Addressed comments from Eric Blake and Greg Kurz Split the fsdev qmp patch into hmp and qmp related patches Moved the common functionalities to throttle.c instead of creating a new file v5 -> v6: Addressed comments from Greg Kurz and Markus Armbruster Split the commits to specific to hmp and throttle as suggested by Greg Moved ThrottleConfig typedef to qemu/typedefs.h Addressed compilation issue on FreeBSD by adding flags in qmp.c v6 -> v7: Addressed comments from Albert Garcia and Dr. David Alan Gilbert Fixed the hmp-commands-info.hx and hmp-commands.hx as per Dr. David's comments. Fixed the bug with the hmp fsdev_set_io_throttle and info fsdev_iothrottle v7 -> v8: Addressed comments from Markus Armbruster and Eric Blake Removed unwanted headers from qmp-fsdev-throttle.h v8 -> v9: Addressed comments from Markus Armbruster and Eric Blake Removed the iothrottle.json and pushed the iothrottle struct to block-core.json v9 -> v10: Addressed comments from Albert Garcia Fixed issue related to dynamically passing throttle configuration Removed some unused code v10 -> v11: Addressed the comments from Markus Armbruster and Eric Blake Rebased the patches over 2.10 -- 1.8.3.1
