* src/qemu/qemu_conf.c (qemudParseHelpStr): Fix errors that made
it impossible to diagnose invalid minor and micro version number
components.

The current cleanup: in StartVMDaemon path is a poor duplication.
qemuShutdownVMDaemon can handle teardown for inactive VMs, so let's use it.
v2: Remove old abort: label, only use cleanup:
This involved a few fixes. To start with,
an virDomainSnapshot object is really tied to a
domain, not a connection, so we have to generate
a slightly different object so that we can get
at self._dom for the object.
Next, we had to "dummy" up an override piece of
XML with a bogus argument that the function doesn't
actually take. That's so that the generator places
virDomainRevertToSnapshot underneath the correct
class (namely, the virDomain class).
Finally, we had to hand-implement the
virDomainRevertToSnapshot implementation, ignoring the
bogus pointer we are being passed.
With all of this in place, I was able to successfully
take a snapshot and revert to it using only the
Python bindings.

* src/qemu/qemu_conf.c (QEMU_VERSION_STR_1, QEMU_VERSION_STR_2):
Define these instead of...
(QEMU_VERSION_STR): ... this. Remove definition.
(qemudParseHelpStr): Check first for the new, shorter prefix,
"QEMU emulator version", and then for the old one,
"QEMU PC emulator version" when trying to parse the version number.
Based on a patch by Chris Wright.
* src/lxc/lxc_controller.c (ignorable_epoll_accept_errno): New function.
(lxcControllerMain): Handle a failed accept carefully:
most errno values indicate legitimate failure and must be fatal.
However, ignore a special case: that in which an incoming client quits
between the poll() indicating its presence, and our accept() which
is trying to process it.
There doesn't seem to be anything specific to tap devices for this
array of file descriptors which need to stay open of the guest to use.
Rename then for others to make use of.

These files may be useful for anyone making modifications to
source files in a tarball distribution.
* src/Makefile.am (EXTRA_DIST): Add THREADS.txt.
* daemon/Makefile.am (EXTRA_DIST): Add THREADING.txt.
This test was failing on systems using pdwtags from dwarves-1.3.
Reported by Matthias Bolte.
Two-pronged fix:
- use --verbose to work also with dwarves-1.3; adapt regular
expressions to handle now-varying separators
- require a minimum number of post-split clauses, in order to
skip upon any future format change.
Currently there are 318; if there are 300 or fewer,
give a warning similar to when pdwtags is missing.
* src/Makefile.am (remote_protocol-structs): Use pdwtags' --verbose
option to make 1.3 emit member sizes and offsets.
Consistently output WARNING messages to stderr.
Do not require each caller of virStorageFileGetMetadata and
virStorageFileGetMetadataFromFD to first clear the storage of the
"meta" buffer. Instead, initialize that storage in
virStorageFileGetMetadataFromFD.
* src/util/storage_file.c (virStorageFileGetMetadataFromFD): Clear
"meta" here, not before each of the following callers.
* src/qemu/qemu_driver.c (qemuSetupDiskCgroup): Don't clear "meta" here.
(qemuTeardownDiskCgroup): Likewise.
* src/qemu/qemu_security_dac.c (qemuSecurityDACSetSecurityImageLabel):
Likewise.
* src/security/security_selinux.c (SELinuxSetSecurityImageLabel):
Likewise.
* src/security/virt-aa-helper.c (get_files): Likewise.
* cfg.mk (sc_prohibit_gettext_markup): New rule, to enforce
this policy. Contrary to most diagnostic-emitting functions,
where we require _(...) markup, here, we require that _() *not*
be used for certain functions (or function-like macros).
Approximately 60 messages were marked. Since these diagnostics are
intended solely for developers and maintainers, encouraging translation
is deemed to be counterproductive:

There were three very similar uses of qemuMonitorAddDrive.
This change makes the three 17-line sequences identical.
* src/qemu/qemu_driver.c (qemudDomainAttachPciDiskDevice): Detect
failure. Add VIR_WARN and braces.
(qemudDomainAttachSCSIDisk): Add VIR_WARN and braces.
(qemudDomainAttachUsbMassstorageDevice): Likewise.
* tests/nodeinfotest.c (linuxTestCompareFiles): Don't use
nodeinfo->member uninitialized. linuxNodeInfoCPUPopulate requires
that some of its nodeinfo members (including threads) be initialized
upon input. The nodeinfotest.c program lacked the initialization,
while the only other use (nodeGetInfo) did perform it.
It's not trivial to move the initialization into the function,
since nodeGetInfo sets at least one member after clearing the
buffer but before calling linuxNodeInfoCPUPopulate.
History has shown that there are frequent bugs in the QEMU driver
code leading to the monitor being invoked with a NULL pointer.
Although the QEMU driver code should always report an error in
this case before invoking the monitor, as a safety net put in a
generic check in the monitor code entry points.

object
