b7da97eef7 monitor: Check whether TCG is enabled before running the "info jit" code
The "info jit" command currently aborts on Mac OS X with the message
"qemu_mutex_lock: Invalid argument" when running with "-M accel=qtest".
We should only call into the TCG code here if TCG has really been
enabled and initialized.

e9628441df hmp: gpa2hva and gpa2hpa hostaddr command
These commands are useful when testing machine-check passthrough.
gpa2hva is useful to inject a MADV_HWPOISON madvise from gdb, while
gpa2hpa is useful to inject an error with the mce-inject kernel
module.

104fc30279 qmp: Drop duplicated QMP command object checks
qmp_check_input_obj() duplicates qmp_dispatch_check_obj(), except the
latter screws up an error message.  handle_qmp_command() runs first
the former, then the latter via qmp_dispatch(), masking the screwup.

qemu-ga also masks the screwup, because it also duplicates checks,
just differently.

qmp_check_input_obj() exists because handle_qmp_command() needs to
examine the command before dispatching it.  The previous commit got
rid of this need, except for a tracepoint, and a bit of "id" code that
relies on qdict not being null.

Fix up the error message in qmp_dispatch_check_obj(), drop
qmp_check_input_obj() and the tracepoint.  Protect the "id" code with
a conditional.

635db18f68 qmp: Clean up how we enforce capability negotiation
To enforce capability negotiation before normal operation,
handle_qmp_command() inspects every command before it's handed off to
qmp_dispatch().  This is a bit of a layering violation, and results in
duplicated code.

Before capability negotiation (!cur_mon->in_command_mode), we fail
commands other than "qmp_capabilities".  This is what enforces
capability negotiation.

Afterwards, we fail command "qmp_capabilities".

Clean this up as follows.

The obvious place to fail a command is the command itself, so move the
"afterwards" check to qmp_qmp_capabilities().

We do the "before" check in every other command, but that would be
bothersome.  Instead, start with an alternate list of commands that
contains only "qmp_capabilities".  Switch to the full list in
qmp_qmp_capabilities().

Additionally, replace the generic human-readable error message for
CommandNotFound by one that reminds the user to run qmp_capabilities.
Without that, we'd regress commit 2d5a834.

0587568780 qmp: Dumb down how we run QMP command registration
The way we get QMP commands registered is high tech:

* qapi-commands.py generates qmp_init_marshal() that does the actual work

* it also generates the magic to register it as a MODULE_INIT_QAPI
  function, so it runs when someone calls
  module_call_init(MODULE_INIT_QAPI)

* main() calls module_call_init()

QEMU needs to register a few non-qapified commands.  Same high tech
works: monitor.c has its own qmp_init_marshal() along with the magic
to make it run in module_call_init(MODULE_INIT_QAPI).

QEMU also needs to unregister commands that are not wanted in this
build's configuration (commit 5032a16).  Simple enough:
qmp_unregister_commands_hack().  The difficulty is to make it run
after the generated qmp_init_marshal().  We can't simply run it in
monitor.c's qmp_init_marshal(), because the order in which the
registered functions run is indeterminate.  So qmp_init_marshal()
registers qmp_unregister_commands_hack() separately.  Since
registering *appends* to the list of registered functions, this will
make it run after all the functions that have been registered already.

I suspect it takes a long and expensive computer science education to
not find this silly.

Dumb it down as follows:

* Drop MODULE_INIT_QAPI entirely

* Give the generated qmp_init_marshal() external linkage.

* Call it instead of module_call_init(MODULE_INIT_QAPI)

* Except in QEMU proper, call new monitor_init_qmp_commands() that in
  turn calls the generated qmp_init_marshal(), registers the
  additional commands and unregisters the unwanted ones.

f99fd7ca2a i386: Implement query-cpu-model-expansion QMP command
Implement query-cpu-model-expansion for target-i386.

This should meet all the requirements while being simple. In the
case of static expansion, it will use the new "base" CPU model,
and in the case of full expansion, it will keep the original CPU
model name+props, and append extra properties.

A future follow-up should improve the implementation of
type=full, so that it returns more detailed data, including every
writable QOM property in the CPU object.

c5514d0e4b machine: replace query_hotpluggable_cpus() callback with has_hotpluggable_cpus flag
Generic helper machine_query_hotpluggable_cpus() replaced
target specific query_hotpluggable_cpus() callbacks so
there is no need in it anymore. However inon NULL callback
value is used to detect/report hotpluggable cpus support,
therefore it can be removed completely.
Replace it with MachineClass.has_hotpluggable_cpus boolean
which is sufficient for the task.

854e67fea6 monitor: Fix crashes when using HMP commands without CPU
When running certain HMP commands ("info registers", "info cpustats",
"info tlb", "nmi", "memsave" or dumping virtual memory) with the "none"
machine, QEMU crashes with a segmentation fault. This happens because the
"none" machine does not have any CPUs by default, but these HMP commands
did not check for a valid CPU pointer yet. Add such checks now, so we get
an error message about the missing CPU instead.

0ab8ed18a6 trace: switch to modular code generation for sub-directories
Introduce rules in the top level Makefile that are able to generate
trace.[ch] files in every subdirectory which has a trace-events file.

The top level directory is handled specially, so instead of creating
trace.h, it creates trace-root.h. This allows sub-directories to
include the top level trace-root.h file, without ambiguity wrt to
the trace.g file in the current sub-dir.

777357d758 chardev: qom-ify
Turn Chardev into Object.

qemu_chr_alloc() is replaced by the qemu_chardev_new() constructor. It
will call qemu_char_open() to open/intialize the chardev with the
ChardevCommon *backend settings.

The CharDriver::create() callback is turned into a ChardevClass::open()
which is called from the newly introduced qemu_chardev_open().

"chardev-gdb" and "chardev-hci" are internal chardev and aren't
creatable directly with -chardev. Use a new internal flag to disable
them. We may want to use TYPE_USER_CREATABLE interface instead, or
perhaps allow -chardev usage.

Although in general we keep typename and macros private, unless the type
is being used by some other file, in this patch, all types and common
helper macros for qemu-char.c are in char.h. This is to help transition
now (some types must be declared early, while some aren't shared) and
when splitting in several units. This is to be improved later.

728b1429b1 qmp: Disable query-cpu-* commands when they're unavailable
Instead of requiring clients to actually call the query-cpu-*
commands to find out if they are implemented, remove them from
the output of "query-commands", so clients know they are not
available.

This is implemented by extending the existing hack at
qmp_unregister_commands_hack(). I wish I could avoid adding even
more #ifdefs to that code, but that's the solution we have today.

Now that we allow CPU hot unplug on a few platforms, we can end up in a
situation where we don't have a CPU with index 0.  Or at least we could,
if we didn't have code to explicitly prohibit unplug of CPU 0.

Longer term we want to allow CPU 0 unplug, this patch is an early step in
allowing this, by removing an assumption in the monitor code that CPU 0
always exists.

c823501ea9 monitor: use qmp_find_command() (using generated qapi code)
Stop using the so-called 'middle' mode. Instead, use qmp_find_command()
from generated qapi commands registry. Update and fix the documentation
too.

5032a16d1d qmp: Hack to keep commands configuration-specific
We currently define QMP commands in two places: the QAPI schema and
qmp-commands.hx.  The latter is preprocessed, the former is not.  We
use the preprocessor to suppress configuration-specific commands.  For
instance, query-spice is only available #ifdef CONFIG_SPICE.

QMP command dispatch and query-commands use the qmp-commands.hx
definition, and thus obey the #ifdeffery there.  Good, because it lets
QMP clients probe for available features more easily.

query-qmp-schema uses the QAPI schema, and thus lists the
configuration-specific commands even when they're unavailable.  Not so
good.

We're about to flip command dispatch and query-commands to the
non-middle-mode command registry, which uses the QAPI schema, so we
can ditch qmp-commands.hx.  To avoid regressing query-commands,
arrange for commands that are suppressed with the preprocessor now to
be unregistered with that registry.  This will keep them unavailable
and out of query-commands when we flip command dispatch and
query-commands to that registry, exactly as before.

This is a hack.  The proper solution is to support
configuration-specific commands in the QAPI schema.  Mark it FIXME.

edcfaefe07 monitor: register gen:false commands manually
Since a few commands are using 'gen': false, they are not registered
automatically by the generator. Register manually instead.

This is in preparation for removal of qapi 'middle' mode generation.

Note that qmp_init_marshal() function isn't run yet, so the commands
aren't actually registered, until module_call_init(MODULE_INIT_QAPI) is
added in a later patch.
