The "info blockstats" documentation was copy-pasted as "info block"
instead of "info blockstats". The documentation for "commands", "jit",
"numa", "qdm", and "roms" is missing. This patch resolves these issues
in qemu-monitor.hx.

Short story: We don't want pci_add in QMP. Long story follows.
pci_add can do two things:
* Hot plug a PCI NIC. device_add is more general.
* Hot plug a PCI disk controller, and a drive connected to it.
The controller is either virtio-blk-pci (if=virtio) or lsi53c895a
(if=scsi). With the latter, the drive is optional. Use drive_add to
hotplug additional SCSI drives. Except drive_add is not available in
QMP.
device_add is more general for controllers and the guest part of
drives. I'm working on a more general alternative for the host part
of drives.
Why am I proposing to remove pci_add from QMP before its replacement is
ready? I want it out sooner rather than later, because it isn't fully
functional (errors and drive_add are missing), and we do not plan to
complete the job. In other words, it's not really usable over QMP now,
and it's not what we want for QMP anyway. Since we don't want it to be
used over QMP, we should take it out, not leave it around as a trap for
the uninitiated.
Dan Berrange confirmed that libvirt has no need for pci_add & friends
over QMP.

This command will be used to enable QMP capabilities advertised
by the capabilities array.
Note that it will be mandatory to issue this command in order
to make QMP functional (although this behavior is not being
enforced by this commit).
Also, as we don't have any capabilities yet, the new command
doesn't accept any arguments. I will postpone the decision for
a format for this until we get our first capability.
Finally, this command is visible from the user Monitor too, in
the meaning that you can execute it but it won't do anything.
Making it only visible in QMP is beyond this series' goal, as
it requires changes in unrelated places.

Before, it used type 's', which strips quotes and interprets escapes,
and is quite inappropriate for QMP.
Negative arguments are no flushed to zero. Before, they were cast to
uint32_t, which wrecked the sign.
Ridiculously large arguments including infinities are now rejected.
Before, they were interpreted as zero. Same for NaN.

When using ballooning to manage overcommitted memory on a host, a system for
guests to communicate their memory usage to the host can provide information
that will minimize the impact of ballooning on the guests. The current method
employs a daemon running in each guest that communicates memory statistics to a
host daemon at a specified time interval. The host daemon aggregates this
information and inflates and/or deflates balloons according to the level of
host memory pressure. This approach is effective but overly complex since a
daemon must be installed inside each guest and coordinated to communicate with
the host. A simpler approach is to collect memory statistics in the virtio
balloon driver and communicate them directly to the hypervisor.

do_migrate_set_speed() accepts a suffix for the 'value' argument and this is

When using encrypted disk images, QEMU will prompt the user
for passwords when started.
This makes sense for the user protocol, but doesn't for QMP.
The solution is to have Monitor command which allows the user
or a Client to set passwords in advance, so that we avoid
the prompt completely.
This is what block_passwd does, for example:
(QEMU) block_passwd ide0-hd0 foobar

The migration command is as follows:

(qemu) migrate -d -b tcp:0:4444 # for live migration with complete storage copy
(qemu) migrate -d -i tcp:0:4444 # for live migration with incremental storage copy, storage is cow based.
