2af282ec51 qemu-storage-daemon: Add --monitor option
This adds and parses the --monitor option, so that a QMP monitor can be
used in the storage daemon. The monitor offers commands defined in the
QAPI schema at storage-daemon/qapi/qapi-schema.json.

The --monitor options currently allows to create multiple monitors with
the same ID. This part of the interface is considered unstable. We will
reject such configurations as soon as we have a design for the monitor
subsystem to perform these checks. (In the system emulator, we depend on
QemuOpts rejecting duplicate IDs.)

Trying to attach a HMP monitor to a chardev that is already in use

f2098725aa monitor: Create QAPIfied monitor_init()
This adds a new QAPI-based monitor_init() function. The existing
monitor_init_opts() is rewritten to simply put its QemuOpts parameter
into a visitor and pass the resulting QAPI object to monitor_init().

This will cause some change in those error messages for the monitor
options in the system emulator that are now generated by the visitor
rather than explicitly checked in monitor_init_opts().

5f07c4d60d qapi: Flatten object-add
Mapping object-add to the command line as is doesn't result in nice
syntax because of the nesting introduced with 'props'. This becomes
nicer and more consistent with device_add and netdev_add when we accept
properties for the object on the top level instead.

'props' is still accepted after this patch, but marked as deprecated.

5a16818b45 block: Move sysemu QMP commands to QAPI block module
QMP commands that are related to the system emulator and don't make
sense in the context of tools such as qemu-storage-daemon should live in
qapi/block.json rather than qapi/block-core.json. Move them there.

The associated data types are actually also used in code shared with the
tools, so they stay in block-core.json.

083b266f69 chardev: Use QEMUChrEvent enum in IOEventHandler typedef
The Chardev events are listed in the QEMUChrEvent enum.

By using the enum in the IOEventHandler typedef we:

- make the IOEventHandler type more explicit (this handler
  process out-of-band information, while the IOReadHandler
  is in-band),
- help static code analyzers.

This patch was produced with the following spatch script:

  @match@
  expression backend, opaque, context, set_open;
  identifier fd_can_read, fd_read, fd_event, be_change;
  @@
  qemu_chr_fe_set_handlers(backend, fd_can_read, fd_read, fd_event,
                           be_change, opaque, context, set_open);

  @depends on match@
  identifier opaque, event;
  identifier match.fd_event;
  @@
   static
  -void fd_event(void *opaque, int event)
  +void fd_event(void *opaque, QEMUChrEvent event)
   {
   ...
   }

Then the typedef was modified manually in
include/chardev/char-fe.h.

The Chardev events are listed in the QEMUChrEvent enum. To be
able to use this enum in the IOEventHandler typedef, we need to
explicit all the events ignored by this frontend, to silent the
following GCC warning:

    CC      monitor/qmp.o
  monitor/qmp.c: In function ‘monitor_qmp_event’:
  monitor/qmp.c:345:5: error: enumeration value ‘CHR_EVENT_BREAK’ not handled in switch [-Werror=switch]

89b6fc4561 hmp: Allow using qdev ID for qemu-io command
In order to issue requests on an existing BlockBackend with the
'qemu-io' HMP command, allow specifying the BlockBackend not only with a
BlockBackend name, but also with a qdev ID/QOM path for a device that
owns the (possibly anonymous) BlockBackend.

Because qdev names could be conflicting with BlockBackend and node
names, introduce a -d option to explicitly address a device. If the
option is not given, a BlockBackend or a node is addressed.

2895aaa139 monitor/qmp: resume monitor when clearing its queue
When a monitor's queue is filled up in handle_qmp_command()
it gets suspended. It's the dispatcher bh's job currently to
resume the monitor, which it does after processing an event
from the queue. However, it is possible for a
CHR_EVENT_CLOSED event to be processed before before the bh
is scheduled, which will clear the queue without resuming
the monitor, thereby preventing the dispatcher from reaching
the resume() call.
Any new connections to the qmp socket will be accept()ed and
show the greeting, but will not respond to any messages sent
afterwards (as they will not be read from the
still-suspended socket).
Fix this by resuming the monitor when clearing a queue which
was filled up.

038adc2f58 core: replace getpagesize() with qemu_real_host_page_size
There are three page size in qemu:

  real host page size
  host page size
  target page size

All of them have dedicate variable to represent. For the last two, we
use the same form in the whole qemu project, while for the first one we
use two forms: qemu_real_host_page_size and getpagesize().

qemu_real_host_page_size is defined to be a replacement of
getpagesize(), so let it serve the role.

[Note] Not fully tested for some arch or device.

54d31236b9 sysemu: Split sysemu/runstate.h off sysemu/sysemu.h
sysemu/sysemu.h is a rather unfocused dumping ground for stuff related
to the system-emulator.  Evidence:

* It's included widely: in my "build everything" tree, changing
  sysemu/sysemu.h still triggers a recompile of some 1100 out of 6600
  objects (not counting tests and objects that don't depend on
  qemu/osdep.h, down from 5400 due to the previous two commits).

* It pulls in more than a dozen additional headers.

Split stuff related to run state management into its own header
sysemu/runstate.h.

Touching sysemu/sysemu.h now recompiles some 850 objects.  qemu/uuid.h
also drops from 1100 to 850, and qapi/qapi-types-run-state.h from 4400
to 4200.  Touching new sysemu/runstate.h recompiles some 500 objects.

Since I'm touching MAINTAINERS to add sysemu/runstate.h anyway, also
add qemu/main-loop.h.

d5938f29fe Clean up inclusion of sysemu/sysemu.h
In my "build everything" tree, changing sysemu/sysemu.h triggers a
recompile of some 5400 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).

Almost a third of its inclusions are actually superfluous.  Delete
them.  Downgrade two more to qapi/qapi-types-run-state.h, and move one
from char/serial.h to char/serial.c.

hw/semihosting/config.c, monitor/monitor.c, qdev-monitor.c, and
stubs/semihost.c define variables declared in sysemu/sysemu.h without
including it.  The compiler is cool with that, but include it anyway.

This doesn't reduce actual use much, as it's still included into
widely included headers.  The next commit will tackle that.

12e9493df9 Include hw/boards.h a bit less
hw/boards.h pulls in almost 60 headers.  The less we include it into
headers, the better.  As a first step, drop superfluous inclusions,
and downgrade some more to what's actually needed.  Gets rid of just
one inclusion into a header.

650d103d3e Include hw/hw.h exactly where needed
In my "build everything" tree, changing hw/hw.h triggers a recompile
of some 2600 out of 6600 objects (not counting tests and objects that
don't depend on qemu/osdep.h).

The previous commits have left only the declaration of hw_error() in
hw/hw.h.  This permits dropping most of its inclusions.  Touching it
now recompiles less than 200 objects.

2ae16a6aa4 Include generated QAPI headers less
Some of the generated qapi-types-MODULE.h are included all over the
place.  Changing a QAPI type can trigger massive recompiling.  Top
scorers recompile more than 1000 out of some 6600 objects (not
counting tests and objects that don't depend on qemu/osdep.h):

    6300 qapi/qapi-builtin-types.h
    5700 qapi/qapi-types-run-state.h
    3900 qapi/qapi-types-common.h
    3300 qapi/qapi-types-sockets.h
    3000 qapi/qapi-types-misc.h
    3000 qapi/qapi-types-crypto.h
    3000 qapi/qapi-types-job.h
    3000 qapi/qapi-types-block-core.h
    2800 qapi/qapi-types-block.h
    1300 qapi/qapi-types-net.h

Clean up headers to include generated QAPI headers only where needed.
Impact is negligible except for hw/qdev-properties.h.

This header includes qapi/qapi-types-block.h and
qapi/qapi-types-misc.h.  They are used only in expansions of property
definition macros such as DEFINE_PROP_BLOCKDEV_ON_ERROR() and
DEFINE_PROP_OFF_AUTO().  Moving their inclusion from
hw/qdev-properties.h to the users of these macros avoids pointless
recompiles.  This is how other property definition macros, such as
DEFINE_PROP_NETDEV(), already work.

Improves things for some of the top scorers:

    3600 qapi/qapi-types-common.h
    2800 qapi/qapi-types-sockets.h
     900 qapi/qapi-types-misc.h
    2200 qapi/qapi-types-crypto.h
    2100 qapi/qapi-types-job.h
    2100 qapi/qapi-types-block-core.h
     270 qapi/qapi-types-block.h

In hmp_change(), the variable hmp_mon is only used
by code under #ifdef CONFIG_VNC. This results in a build
error when VNC is configured out with the default of
treating warnings as errors:

monitor/hmp-cmds.c: In function ‘hmp_change’:
