[Qemu-devel] [PATCH RFC v2 08/12] VMState test: hmp interface for querying the vmstate testing process

[Sanidhya Kashyap <sanidhya.iiith@gmail.com>]

Added a hmp interface for providing the information about the testing process.
I have used the underscore as a separater on Eric's advice. But, I have found
some of the commands having hyphen.
