c29b652912 qemu: monitor: Add argument for specifying backing name for block commit
To allow changing the name that is recorded in the overlay of the TOP
image used in a block commit operation, we need to specify the backing
name to qemu. This is done via the "backing-file" attribute to the
block-commit command.

47549d5a17 blockjob: allow omitted arguments to QMP block-commit
We are about to turn on support for active block commit.  Although
qemu 2.0 was the first version to mostly support it, that version
mis-handles 0-length files, and doesn't have anything available for
easy probing.  But qemu 2.1 fixed bugs, and made life simpler by
letting the 'top' argument be optional.  Unless someone begs for
active commit with qemu 2.0, for now we are just going to enable
it only by probing for qemu 2.1 behavior (anyone backporting active
commit can also backport the optional argument behavior).  This
requires qemu.git commit 7676e2c597000eff3a7233b40cca768b358f9bc9.

Although all our actual uses of block-commit supply arguments for
both base and top, we can omit both arguments and use a bogus
device string to trigger an interesting behavior in qemu.  All QMP
commands first do argument validation, failing with GenericError
if a mandatory argument is missing.  Once that passes, the code
in the specific command gets to do further checking, and the qemu
developers made sure that if device is the only supplied argument,
then the block-commit code will look up the device first, with a
failure of DeviceNotFound, before attempting any further argument
validation (most other validations fail with GenericError).  Thus,
the category of error class can reliably be used to decipher
whether the top argument was optional, which in turn implies a
working active commit.  Since we expect our bogus device string to
trigger an error either way, the code is written to return a
distinct return value without spamming the logs.

ce2107a9a0 qemu: monitor: Fix type of holdtime argument in qemuMonitorJSONSendKey
qemuMonitorJSONSendKey declares the "holdtime" argument as unsigned int
while the command was constructed in qemuMonitorJSONMakeCommand using
the "P" modifier which took a unsigned long from the variable
arguments which then made it possible to access uninitialized memory.

This broke the qemumonitorjsontest on 32bit fedora 20:
64) qemuMonitorJSONSendKey
... libvirt: QEMU Driver error : internal error: unsupported data type 'W' for arg 'WVSƒì ‹D$0è‘wÿÿÃAå' FAILED

84f6960214 qemu: Check for presence of device and properities when getting CPUID
The QOM path in qemu that contains the CPUID registers of a running VM
may not be present (introduced in QEMU 1.5).

Since commit d94b781771 we have a regression with QEMU that don't
support reporting of the CPUID register state via the monitor as the
process startup code expects the path to exist.

This patch adds code that checks with the monitor if the requested path
already exists and uses it only in this case.

The test does a "{"execute":"qom-list", "arguments": { "path": "/"}}" which
returns "{"return": [{"name": "machine", "type": "child<container>"},
{"name": "type", "type": "string"}]}" resulting in a return of an array
of 2 elements with [0].name="machine", [0].type="child<container>".  The [1]
entry appears to be a header that could be used some day via a command such
as "virsh qemuobject --list" to format output.

bd56d0d813 qemu: query command line options in QMP
Ever since the conversion to using only QMP for probing features
of qemu 1.2 and newer, we have been unable to detect features
that are added only by additional command line options.  For
example, we'd like to know if '-machine mem-merge=on' (added
in qemu 1.5) is present.  To do this, we will take advantage
of qemu 1.5's query-command-line-parameters QMP call [1].

This patch wires up the framework for probing the command results;
if the QMP command is missing, or if a particular command line
option does not output any parameters (for example, -net uses
a polymorphic parser, which showed up as no parameters as of qemu
1.5), we silently treat that command as having no results.

27cf98e2d1 virCaps: conf: start splitting out irrelevat data
The virCaps structure gathered a ton of irrelevant data over time that.
The original reason is that it was propagated to the XML parser
functions.

This patch aims to create a new data structure virDomainXMLConf that
will contain immutable data that are used by the XML parser. This will
allow two things we need:

1) Get rid of the stuff from virCaps

2) Allow us to add callbacks to check and add driver specific stuff
after domain XML is parsed.

This first attempt removes pointers to private data allocation functions
to this new structure and update all callers and function that require
them.
