Make "drive_backup" available on the HMP monitor:

  drive_backup [-n] [-f] device target [format]

The -n flag requests QEMU to reuse the image found in new-image-file,
instead of recreating it from scratch.

The -f flag requests QEMU to copy the whole disk, so that the result
does not need a backing file.  Note that this flag *must* currently be
passed since the other sync modes ('none' and 'top') have not been
implemented yet.  Requiring it ensures that "drive_backup" behaves like
"drive_mirror".

This patch adds support for TPM command line options.
The command line options supported here are

./qemu-... -tpmdev passthrough,path=<path to TPM device>,id=<id>
           -device tpm-tis,tpmdev=<id>,id=<other id>

and

./qemu-... -tpmdev help

where the latter works similar to -soundhw help and shows a list of
available TPM backends (for example 'passthrough').

Using the type parameter, the backend is chosen, i.e., 'passthrough' for the
passthrough driver. The interpretation of the other parameters along
with determining whether enough parameters were provided is pushed into
the backend driver, which needs to implement the interface function
'create' and return a TPMDriverOpts structure if the VM can be started or
'NULL' if not enough or bad parameters were provided.

Monitor support for 'info tpm' has been added. It for example prints the
following:

(qemu) info tpm
TPM devices:
 tpm0: model=tpm-tis
  \ tpm0: type=passthrough,path=/dev/tpm0,cancel-path=/sys/devices/pnp0/00:09/cancel

New device, has never been released, so we can still improve things
without worrying about compatibility.

Naming is a mess.  The code calls the device driver CirMemCharDriver,
the public API calls it "memory", "memchardev", or "memchar", and the
special commands are named like "memchar-FOO".  "memory" is a
particularly unfortunate choice, because there's another character
device driver called MemoryDriver.  Moreover, the device's distinctive
property is that it's a ring buffer, not that's in memory.  Therefore:

* Rename CirMemCharDriver to RingBufCharDriver, and call the thing a
  "ringbuf" in the API.

* Rename QMP and HMP commands from memchar-FOO to ringbuf-FOO.

* Rename device parameter from maxcapacity to size (simple words are
  good for you).

* Clearly mark the parameter as optional in documentation.

* Fix error reporting so that chardev-add reports to current monitor,
  not stderr.

* Replace cirmem in C identifiers by ringbuf.

* Rework documentation.  Document the impact of our crappy UTF-8
  handling on reading.

* QMP examples that even work.

I could split this up into multiple commits, but they'd change the
same documentation lines multiple times.  Not worth it.

While streaming can be dropped as soon as it progressed through the whole
image, mirroring needs to be completed manually for two reasons: 1) so that
management knows exactly when the VM switches to the target; 2) because
for other use cases such as replication, we may leave the operation running
for the whole life of the virtual machine.

Convert 'sendkey' to use QAPI.

QAPI passes key's index of mapping table to qmp_send_key(),
not keycode. So we use help functions to convert key/code to
index of key_defs, and 'index' will be converted to 'keycode'
inside qmp_send_key().

For qmp, QAPI would check invalid key and raise error.
For hmp, invalid key is checked in hmp_send_key().

'send-key' of QMP doesn't support key in hexadecimal format.
