Kevin Wolf 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.)

Peter Maydell 2b63ec5fb2 scripts/hxtool-conv: Archive script used in qemu-options.hx conversion
This commit archives the perl script used to do conversion of the
STEXI/ETEXI blocks in qemu-options.hx. (The other .hx files were
manually converted, but qemu-options.hx is complicated enough that
I felt I needed some scripting.)

Paolo BonziniandPeter Maydell 41955e1b6f texi2pod: parse @include directives outside "@c man" blocks
This enables splitting the huge qemu-doc.texi file and keeping parallel
Texinfo and rST versions of the documentation.  texi2pod is not going to
live much longer and hardly anyone cares about its upstream status,
so the temporary fork should be acceptable.

Peter MaydellandPhilippe Mathieu-Daudé 19f7034773 Avoid address_space_rw() with a constant is_write argument
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
