Commit 3e9fab690d59ac15956c3733fe0794ce1ae4c4af ("block: Add support for
throttling burst max in QMP and the command line.") introduced bogus
"[not inserted]" output, possibly due to a merge failure. Remove this
artifact.
Output of 'info block'
scsi0-hd0: /images/f18-ppc64.qcow2 (qcow2)

scsi0-cd2: [not inserted]
Removable device: not locked, tray closed
floppy0: [not inserted]
Removable device: not locked, tray closed

Removable device: not locked, tray closed
There will be no additional lines between scsi0-hd0 and
scsi0-cd2.
At the same time, scsi0-hd0 already inserted, but still has
'[not inserted]' flag. This line should be removed.
This patch is to solve this.

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".

HMP is meant for humans and you should notice it.
This changes the output format to use a bit more space to display the

mention only that an image is encrypted, but not when it's not; display
I/O limits only if throttling is in effect; ...)

during bulk stage of ram migration if a page is a
zero page do not send it at all.
the memory at the destination reads as zero anyway.
even if there is an madvise with QEMU_MADV_DONTNEED
at the target upon receipt of a zero page I have observed
that the target starts swapping if the memory is overcommitted.
it seems that the pages are dropped asynchronously.

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.

Command memchar-write takes data and size parameter. Begs the
question what happens when data doesn't match size.
With format base64, qmp_memchar_write() copies the full data argument,
regardless of size argument.
With format utf8, qmp_memchar_write() copies size bytes from data,
happily reading beyond data. Copies crap from the heap or even
crashes.
Drop the size parameter, and always copy the full data argument.

The desired granularity may be very different depending on the kind of
operation (e.g. continuous replication vs. collapse-to-raw) and whether
the VM is expected to perform lots of I/O while mirroring is in progress.
Allow the user to customize it, while providing a sane default so that
in general there will be no extra allocated space in the target compared
to the source.

Error management is important for mirroring; otherwise, an error on the
target (even something as "innocent" as ENOSPC) requires to start again
with a full copy. Similar to on_read_error/on_write_error, two separate
knobs are provided for on_source_error (reads) and on_target_error (writes).
The default is 'report' for both.
The 'ignore' policy will leave the sector dirty, so that it will be
retried later. Thus, it will not cause corruption.

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.
Add a new block job command that manually completes background operations.
