Subject: [PATCH] monitor/hmp: add support for flag argument with value

Adds support for the "-xS" parameter type, where "-x" denotes a flag

name and the "S" suffix indicates that this flag is supposed to take an

arbitrary string parameter.

These parameters are always optional, the entry in the qdict will be

omitted if the flag is not given.
