Segmented translation through the CRIS MMU is only done for
accesses in kernel mode. In user-mode, all accesses are treated
as paged regardless of the mode config in RW_MM_CFG.

Just like we call into pcnet_poll_timer on stop, we need to call it on
start to trigger the setup of the poll timer.

This state field was never used, simply remained 0. Drop it from the
PCNetState and update the save/restore code accordingly, keeping
backward compatibility.

Each CPU information is stored in a QDict and the returned
QObject is a QList of all CPUs.
The QDict contains the following information:
- "CPU": cpu index
- "current": "yes" or "no"
- "pc": current PC
- "halted": "yes" or "no"
The user output in the Monitor should not change and the
future monitor protocol is expected to emit something like:
[ { "CPU": 0, "current": "yes", "pc": 0x..., "halted": "no" },
{ "CPU": 1, "current": "no", "pc": 0x..., "halted": "yes" } ]
which corresponds to the following user output:
* CPU #0: pc=0x00000000fffffff0
CPU #1: pc=0x00000000fffffff0 (halted)

On success return a QInt with the balloon's value.
This also introduces monitor_print_balloon() to print the
balloon information in the user protocol.
Please, note that errors are not being converted yet.

The returned data is always a QString.
Also introduces monitor_print_qobject(), which can be used as
a standard way to print QObjects in the user protocol format.

It is important to note that it never fails, as big refactoring
of the virtio code would be needed to get the proper error code.

Appropriate error handling support will be needed to have
encrypted images working under the future machine protocol,
but this initial conversion will work with the current
user protocol.

do_info() is special, its job is to call 'info handlers'.
This is similar to what monitor_handle_command() does,
therefore do_info() also has to distinguish among new and
old style info handlers.
This commit converts do_info() to the new QObject style and
makes the appropriate changes so that it can handle both
info handlers styles.
In the future, when all handlers are converted to QObject's
style, it will be possible to share more code with
monitor_handle_command().
This commit also introduces a new function called
monitor_user_noop(), it should be used by handlers which do
not have data to print.
This is the case of do_info().

This commit changes monitor_handle_command() to support old style
_and_ new style handlers.
New style handlers are protocol independent, they return their
data to the Monitor, which in turn decides how to print them
(ie. user protocol vs. machine protocol).
Converted handlers will use the 'user_print' member of 'mon_cmd_t'
to define its user protocol function, which will be called to print
data in the user protocol format.
Handlers which don't have 'user_print' defined are not converted
and are handled as usual.

This new struct member will store a pointer to a function that
should be used to output data in the user protocol format.
It will also serve as a flag to say if a given handler has already
been converted to the new QObject style.

To execute it you should have check installed and build QEMU with

QList is a high-level data type that can be used to store QObjects
in a singly-linked list.
The following functions are available:
- qlist_new() Create a new QList
- qlist_append() Append a QObject to the list
- qlist_iter() Iterate over stored QObjects

It is convenient that QDECREF() and QINCREF() accept the QObject
parameter to be NULL, so that we don't duplicate 'if' tests in
the callers.
