virtio: Add memory statistics reporting to the balloon driver
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.

New API for asynchronous monitor commands
Qemu has a number of commands that can operate asynchronously (savevm, migrate,
etc) and it will be getting more. For these commands, the user monitor needs
to be suspended, but QMP monitors could continue to to accept other commands.
This patch introduces a new command API that isolates the details of handling
different monitor types from the actual command execution.
A monitor command can use this API by implementing the mhandler.cmd_async
handler (or info_async if appropriate). This function is responsible for
submitting the command and does not return any data although it may raise
errors. When the command completes, the QMPCompletion callback should be
invoked with its opaque data and the command result.
The process for submitting and completing an asynchronous command is different
for QMP and user monitors. A user monitor must be suspended at submit time and
resumed at completion time. The user_print() function must be passed to the
QMPCompletion callback so the result can be displayed properly. QMP monitors
are simpler. No submit time setup is required. When the command completes,
monitor_protocol_emitter() writes the result in JSON format.
This API can also be used to implement synchronous commands. In this case, the
cmd_async handler should immediately call the QMPCompletion callback. It is my
hope that this new interface will work for all commands, leading to a
drastically simplified monitor.c once all commands are ported.

json: escape u0000 .. u001F when outputting json
Markus Armbruster pointed out:
JSON requires control characters in strings to be escaped. RFC 4627
section 2.5:
A string begins and ends with quotation marks. All Unicode
characters may be placed within the quotation marks except for the
characters that must be escaped: quotation mark, reverse solidus, and
the control characters (U+0000 through U+001F).
We've been quoting the special escape sequences that JSON defines but we
haven't been encoding the full control character range. This patch fixes that.

So it loops for 100(64h) times reading register C before BSOD. Lets
reduce number of immediate reinjection well under this limit.

block: prevent multiwrite_merge from creating too large iovecs
If we go over the maximum number of iovecs support by syscall we get
back EINVAL from the kernel which translate to I/O errors for the guest.

QMP: Fix asynchronous events delivery
Commit
f039a563f200beee80cc10fd70b21ea396979dab introduces
a regression as monitor_protocol_event() will return in
the first user Monitor it finds in the QLIST_FOREACH()
loop.
The right thing to do is to only delivery an asynchronous
event if the 'mon' is a QMP Monitor.
The aforementioned commit was an early version, if it was
applied to stable (it should) this one has to be applied
there too.
