69ca3ea5e1 QMP: Add cpu-add command
Adds "cpu-add id=xxx" QMP command.

cpu-add's "id" argument is a CPU number in a range [0..max-cpus)

Example QMP command:
 -> { "execute": "cpu-add", "arguments": { "id": 2 } }
 <- { "return": {} }

f1c72795af migration: do not sent zero pages in bulk stage
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 also updates QMP to return the number of
skipped pages in MigrationStats.

d1a0cf738d Support for TPM command line options
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

                                               "device":"/dev/ttyS0"} } } }

becomes

    { "execute" : "chardev-add",
      "arguments" : { "id" : "ser0",
                      "backend" : { "type" : "serial",
                                    "data" : { "device":"/dev/ttyS0"} } } }

Bonus: nicer error messages.  "unknown chardev port (1)" becomes
"character device backend type 'parallel' not supported".

3949e59414 qemu-char: Saner naming of memchar stuff & doc fixes
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.

82e59a676c qmp: Fix design bug and read beyond buffer in memchar-write
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.

264986e2c8 tap: multiqueue support
Recently, linux support multiqueue tap which could let userspace call TUNSETIFF
for a signle device many times to create multiple file descriptors as
independent queues. User could also enable/disabe a specific queue through
TUNSETQUEUE.

The patch adds the generic infrastructure to create multiqueue taps. To achieve
this a new parameter "queues" were introduced to specify how many queues were
expected to be created for tap by qemu itself. Alternatively, management could
also pass multiple pre-created tap file descriptors separated with ':' through a
new parameter fds like -netdev tap,id=hn0,fds="X:Y:..:Z". Multiple vhost file
descriptors could also be passed in this way.

Each TAPState were still associated to a tap fd, which mean multiple TAPStates
were created when user needs multiqueue taps. Since each TAPState contains one
NetClientState, with the multiqueue nic support, an N peers of NetClientState
were built up.

A new parameter, mq_required were introduce in tap_open() to create multiqueue
tap fds.

eee13dfe30 mirror: allow customizing the granularity
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.

01ceb97e7b balloon: drop old stats code & API
Next commit will re-enable balloon stats with a different interface, but
this old code conflicts with it. Let's drop it.

It's important to note that the QMP and HMP interfaces are also dropped
by this commit. That shouldn't be a problem though, because:

 1. All QMP fields are optional
 2. This feature has always been disabled

0a1a7fabda chardev: add pty chardev support to chardev-add (qmp)
The ptsname is returned directly, so there is no need to
use query-chardev to figure the pty device path.

f6bd5d6ec5 chardev: add socket chardev support to chardev-add (qmp)
qemu_chr_open_socket is split into two functions.  All initialization
after creating the socket file handler is split away into the new
qemu_chr_open_socket_fd function.

chr->filename doesn't get filled from QemuOpts any more.  Qemu gathers
the information using getsockname and getnameinfo instead.  This way it
will also work correctly for file handles passed via file descriptor
passing.

Finally qmp_chardev_open_socket() is the actual qmp hotplug
implementation which basically just calls socket_listen or
socket_connect and the new qemu_chr_open_socket_fd function.

d59044ef74 chardev: add serial chardev support to chardev-add (qmp)
Similar to file, except that no separate in/out files are supported
because it's pointless for direct device access.  Also the special
tty ioctl hooks (pass through linespeed settings etc) are activated
on Unix.
