[Qemu-devel] [RFC PATCH 32/56] hmp: Make block_set_io_throttle's arguments unsigned

[Markus Armbruster <armbru@redhat.com>]

The previous commit made them unsigned in QMP.  Switch HMP's args_type
from 'l' to 'o'.  Loses support for expressions (QEMU pocket
calculator), gains support for unit suffixes.  Negative values are no
longer accepted and interpreted modulo 2^64.  Instead, values between
2^63 and 2^64-1 are now accepted.
