Originally QMP goes through these steps:
JSON Parser --> QMP Dispatcher --> Respond
/|\ (2) (3) |
(1) | \|/ (4)
+--------- main thread --------+
This patch does this:
JSON Parser QMP Dispatcher --> Respond
/|\ | /|\ (4) |
| | (2) | (3) | (5)
(1) | +-----> | \|/
+--------- main thread <-------+
So the parsing job and the dispatching job is isolated now. It gives us
a chance in follow up patches to totally move the parser outside.
The isolation is done using one QEMUBH. Only one dispatcher QEMUBH is
used for all the monitors.

This patches allows QMP monitors to be suspended/resumed.
One thing to mention is that for QMPs that are using IOThreads, we need
an explicit kick for the IOThread in case it is sleeping.
Meanwhile, we need to take special care on non-interactive HMPs.
Currently only gdbserver is using that. For these monitors, we still
don't allow suspend/resume operations.
Since at it, add traces for the operations.

[eblake: rebase to qobject_to() usage]
Signed-off-by: Eric Blake <eblake@redhat.com>
There were no QMP capabilities defined. Define the first capability,
"oob", to allow out-of-band messages.
After this patch, we will allow QMP clients to enable QMP capabilities
when sending the first "qmp_capabilities" command. Originally we are
starting QMP session with no arguments like:
{ "execute": "qmp_capabilities" }
Now we can enable some QMP capabilities using (take OOB as example,
which is the only capability that we support):
{ "execute": "qmp_capabilities",
"arguments": { "enable": [ "oob" ] } }
When the "arguments" key is not provided, no capability is enabled.
For capability "oob", the monitor needs to be run on a dedicated IO
thread, otherwise the command will fail. For example, trying to enable
OOB on a MUXed typed QMP monitor will fail.
One thing to mention is that QMP capabilities are per-monitor, and also
when the connection is closed due to some reason, the capabilities will
be reset.
Also, touch up qmp-test.c to test the new bits.

For each Monitor, add one field "use_io_thr" to show whether it will be
using the dedicated monitor IO thread to handle input/output. When set,
monitor IO parsing work will be offloaded to the dedicated monitor IO
thread, rather than the original main loop thread.
This only works for QMP. HMP will always be run on the main loop
thread.
Currently we're still keeping use_io_thr off always. Will turn it on
later at some point.
One thing to mention is that we cannot set use_io_thr for every QMP
monitor. The problem is that MUXed typed chardevs may not work well
with it now. When MUX is used, frontend of chardev can be the monitor
plus something else. The only thing we know would be safe to be run
outside main thread so far is the monitor frontend. All the rest of the
frontends should still be run in main thread only.

There are many places where the monitor initializes its globals:
- monitor_init_qmp_commands() at the very beginning
- single function to init monitor_lock
- in the first entry of monitor_init() using "is_first_init"
Unify them a bit.
monitor_lock is not used before monitor_init() (as confirmed by code
analysis and gdb watchpoints); so we are safe delaying what was a
constructor-time initialization of the mutex into the later first call
to monitor_init().

In monitor_qmp_read(), we have the hack to temporarily replace the
cur_mon pointer. Now we move this hack deeper inside the QMP dispatcher
routine since the Monitor pointer can be actually obtained using
container_of() upon the parser object, just like most of the other JSON
parser users do.
This does not make much sense as a single patch. However, this will be
a big step for the next patch, when the QMP dispatcher routine will be
split from the QMP parser.

o HMP profits from the less disruptive cpu information retrieval
o HMP 'info cpus' won't display architecture specific data anymore,
which should be tolerable in the light of the deprecation of
query-cpus.

If a CPU selected with the "cpu" command is hot-unplugged then "info cpus"
causes QEMU to exit:
(qemu) device_del cpu1
(qemu) info cpus
qemu:qemu_cpu_kick_thread: No such process
This happens because "cpu" stores the pointer to the selected CPU into
the monitor structure. When the CPU is hot-unplugged, we end up with a
dangling pointer. The "info cpus" command then does:
hmp_info_cpus()
monitor_get_cpu_index()
mon_get_cpu()
cpu_synchronize_state() <--- called with dangling pointer
This could cause a QEMU crash as well.
This patch switches the monitor to store the QOM path instead of a
pointer to the current CPU. The path is then resolved when needed.
If the resolution fails, we assume that the CPU was removed and the
path is resetted to the default (ie, path of first_cpu).

Now that every target is using the disas_set_info hook,
the flags argument is unused. Remove it.

This adds a new "-d" switch to "info mtree" to print dispatch tree
internals.
This changes the way "-f" is handled - it prints now flat views and
associated address spaces.

Currently, the FOO_lookup[] generated for QAPI enum types are
terminated by a NULL sentinel.
A future patch will generate enums with "holes". NULL-termination
will cease to work then.
To prepare for that, replace "have we reached the sentinel?"
predicates by "have we reached the FOO__MAX value?" predicates.

We are malloc'ing a QString and spending CPU cycles on converting a
QObject to string, just for the sake of sticking the string in the trace
message. Wasted when we aren't tracing. Avoid that.
[Commit message and description suggested by Markus Armbruster to
provide more detail about the rationale for this patch.
Use trace_event_get_state_backends() instead of trace_event_get_state()
to honor DTrace/UST backend dstates.

though we already have QDECREF(E) for that purpose. We can update
our coccinelle script to catch any future relapses; with that in
