The traditional QMP command handler interface
int qmp_FOO(Monitor *mon, const QDict *params, QObject **ret_data);
doesn't provide for returning an Error object. Instead, the handler
is expected to stash it in the monitor with qerror_report().
When we rebased QMP on top of QAPI, we didn't change this interface.
Instead, commit 776574d introduced "middle mode" as a temporary aid
for converting existing QMP commands to QAPI one by one. More than
three years later, we're still using it.
Middle mode has two effects:
* Instead of the native input marshallers
static void qmp_marshal_input_FOO(QDict *, QObject **, Error **)
it generates input marshallers conforming to the traditional QMP
command handler interface.
* It suppresses generation of code to register them with
qmp_register_command()
This permits giving them internal linkage.
As long as we need qmp-commands.hx, we can't use the registry behind
qmp_register_command(), so the latter has to stay for now.
The former has to go to get rid of qerror_report(). Changing all QMP
commands to fit the QAPI mold in one go was impractical back when we
started, but by now there are just a few stragglers left:
do_qmp_capabilities(), qmp_qom_set(), qmp_qom_get(), qmp_object_add(),
qmp_netdev_add(), do_device_add().
Switch middle mode to generate native input marshallers, and adapt the
stragglers. Simplifies both the monitor code and the stragglers.
Rename do_qmp_capabilities() to qmp_capabilities(), and
do_device_add() to qmp_device_add, because that's how QMP command
handlers are named today.

The enum string table parameters in various QOM/QAPI methods
are declared 'const char *strings[]'. This results in const
warnings if passed a variable that was declared as
static const char * const strings[] = { .... };
Add the extra const annotation to the parameters, since
neither the string elements, nor the array itself should
ever be modified.

Anything but --type sync (which is the default) suppresses output
entirely, which makes no sense.
Dates back to the initial commit c17d990. Commit message says
"Currently only generators for synchronous qapi/qmp functions are
supported", so maybe output other than "synchronous qapi/qmp" was
planned at the time, to be selected with --type.
Should other kinds of output ever materialize, we can put the option
back.

Continuing the string of cleanups for supporting downstream names
containing '.', this patch focuses on ensuring c_type() can
handle a downstream name. This patch alone does not fix the
places where generator output should be calling this function
but was open-coding things instead, but it gets us a step closer.
In particular, the changes to c_list_type() and type_name() mean
that type_name(FOO) now handles the case when FOO contains '.',
'-', or is a ticklish identifier other than a builtin (builtins
are exempted because ['int'] must remain mapped to 'intList' and
not 'q_intList'). Meanwhile, ['unix'] now maps to 'q_unixList'
rather than 'unixList', to match the fact that 'unix' is ticklish;
however, our naming conventions state that complex types should
start with a capital, so no type name following conventions will
ever have the 'q_' prepended.
Likewise, changes to c_type() mean that c_type(FOO) properly
handles an enum or complex type FOO with '.' or '-' in the
name, or is a ticklish identifier (again, a ticklish identifier
as a type name violates conventions).

c_type() is designed to be called on both string names and on
array designations, so 'name' is a bit misleading because it
operates on more than strings. Also, no caller ever passes
an empty string. Finally, + notation is a bit nicer to read
than '%s' % value for string concatenation.

Now that the two functions are identical, we only need one of them,

c_fun() maps '.' to '_', c_var() doesn't. Nothing prevents '.' in
QAPI names that get passed to c_var().
Which QAPI names get passed to c_fun(), to c_var(), or to both is not
obvious. Names of command parameters and struct type members get
passed to c_var().
c_var() strips a leading '*', but this cannot happen. c_fun()
doesn't.
Fix c_var() to work exactly like c_fun().
Perhaps they should be replaced by a single mapping function.

Add a verbose flag that shows the QMP command that was
constructed, to allow for later copy/pasting, reference,
debugging, etc.
The QMP is converted from a Python literal to JSON first,
to ensure that it is viable input to the actual QMP parser.
As a side-effect, this JSON output will helpfully show all
the necessary conversions that were performed on the input,
illustrating that "True" was transformed back into "true",
literal values are now escaped with "" instead of '', and so on.

Add a special processing mode to craft transactions.
By entering "transaction(" the shell will enter a special
mode where each subsequent command will be saved as a transaction
instead of executed as an individual command.
The transaction can be submitted by entering ")" on a line by itself.
Examples:
Separate lines:
(QEMU) transaction(
TRANS> block-dirty-bitmap-add node=drive0 name=bitmap1
TRANS> block-dirty-bitmap-clear node=drive0 name=bitmap0
TRANS> )
With a transaction action included on the first line:
(QEMU) transaction( block-dirty-bitmap-add node=drive0 name=bitmap2
TRANS> block-dirty-bitmap-add node=drive0 name=bitmap3
TRANS> )
As a one-liner, with just one transaction action:
(QEMU) transaction( block-dirty-bitmap-add node=drive0 name=bitmap0 )
As a side-effect of this patch, blank lines are now parsed as no-ops,
regardless of which shell mode you are in.

This includes support for [] expressions, single-quotes in
QMP expressions (which is not strictly a part of JSON), and
the ability to use "True", "False" and "None" literals instead
of JSON's equivalent true, false, and null literals.
qmp-shell currently allows you to describe values as
JSON expressions:
key={"key":{"key2":"val"}}
But it does not currently support arrays, which are needed
for serializing and deserializing transactions:
key=[{"type":"drive-backup","data":{...}}]
qmp-shell also only currently accepts doubly quoted strings
as-per JSON spec, but QMP allows single quotes.
Lastly, python allows you to utilize "True" or "False" as
boolean literals, but JSON expects "true" or "false". Expand
qmp-shell to allow the user to type either, converting to the
correct type.
As a consequence of the above, the key=val parsing is also improved
to give better error messages if a key=val token is not provided.
CAVEAT: The parser is still extremely rudimentary and does not
expect to find spaces in {} nor [] expressions. This patch does
not improve this functionality.

Our type inheritance for both 'struct' and for flat 'union' merges
key/value pairs from the base class with those from the type in
question. Although the C code currently boxes things so that there
is a distinction between which member is referred to, the QMP wire
format does not allow passing a key more than once in a single
object. Besides, if we ever change the generated C code to not be
quite so boxy, we'd want to avoid duplicate member names there,
too.
Fix a testsuite entry added in an earlier patch, as well as adding
a couple more tests to ensure we have appropriate coverage. Ensure
that collisions are detected, regardless of whether there is a
difference in opinion on whether the member name is optional.

The handling of \ inside QAPI strings was less than ideal, and
really only worked JSON's \/, \\, \", and our extension of \'
(an obvious extension, when you realize we use '' instead of ""
for strings). For other things, like '\n', it resulted in a
literal 'n' instead of a newline.
Of course, at the moment, we really have no use for escaped
characters, as QAPI has to map to C identifiers, and we currently
support ASCII only for that. But down the road, we may add
support for default values for string parameters to a command
or struct; if that happens, it would be nice to correctly support
all JSON escape sequences, such as \n or \uXXXX. This gets us
closer, by supporting Unicode escapes in the ASCII range.
Since JSON does not require \OCTAL or \xXX escapes, and our QMP
implementation does not understand them either, I intentionally
reject it here, but it would be an easy addition if we desired it.
Likewise, intentionally refusing the NUL byte means we don't have
to worry about C strings being shorter than the qapi input.
