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.)

Signed-off-by: Philippe Mathieu-Daudé <philmd@redhat.com>
The address_space_rw() function allows either reads or writes
depending on the is_write argument passed to it; this is useful
when the direction of the access is determined programmatically
(as for instance when handling the KVM_EXIT_MMIO exit reason).
Under the hood it just calls either address_space_write() or
address_space_read_full().
We also use it a lot with a constant is_write argument, though,
which has two issues:
* when reading "address_space_rw(..., 1)" this is less
immediately clear to the reader as being a write than
"address_space_write(...)"
* calling address_space_rw() bypasses the optimization
in address_space_read() that fast-paths reads of a
fixed length

We want to add support for including rST document fragments
in our .hx files, in the same way we currently have texinfo
fragments. These will be delimited by SRST and ERST directives,
in the same way the texinfo is delimited by STEXI/ETEXI.
The rST fragments will not be extracted by the hxtool
script, but by a different mechanism, so all we need to
do in hxtool is have it ignore all the text inside a
SRST/ERST section, with suitable error-checking for
mismatched rST-vs-texi fragment delimiters.
The resulting effective state machine has only three states:
* flag = 0, rstflag = 0 : reading section for C output
* flag = 1, rstflag = 0 : reading texi fragment
* flag = 0, rstflag = 1 : reading rST fragment
and flag = 1, rstflag = 1 is not possible. Using two
variables makes the parallel between the rST handling and
the texi handling clearer; in any case all this code will
be deleted once we've converted entirely to rST.

Recent commit 3e7fb5811b "qapi: Fix code generation for empty modules"
modules" switched QAPISchema.visit() from
for entity in self._entity_list:
effectively to
for mod in self._module_dict.values():
for entity in mod._entity_list:
Visits in the same order as long as .values() is in insertion order.
That's the case only for Python 3.6 and later. Before, it's in some
arbitrary order, which results in broken generated code.
Fix by making self._module_dict an OrderedDict rather than a dict.

Surprisingly, QEMU does have a pretty consistent doc comment style and
it is not very different from the Linux kernel's. Of the documentation
"sigils", only "#" separates the QEMU doc comment style from Linux's,
and it has 200+ instances vs. 6 for the kernel's '&struct foo' (all in
accel/tcg/translate-all.c), so it's clear that the two standards are
different in this respect. In addition, our structs are typedefed and
recognized by CamelCase names.
Adjust kernel-doc's parser for these two aspects of the QEMU coding
standards. The patch has been valid, with hardly any change, for over
two years, so it should not be an issue to keep kernel-doc in sync with
the Linux copy.
