The api builder always associates comments to the last member it read,
not to the current member even if there was a comment for the previous
member and a comma was already seen.

This has the effect that the comment for the previous member gets
overwritten and the current member has no comment at all.

required by VIR_ONCE_GLOBAL_INIT using virSetError.

that broke the build like:

  CC     libvirt_conf_la-domain_conf.lo
  conf/domain_conf.c: In function 'virDomainVcpuPinAdd':
  conf/domain_conf.c:11920:29: error: 'vpcupin' undeclared (first use in this function)
  conf/domain_conf.c:11920:29: note: each undeclared identifier is reported only once for each function it appears in
  make[3]: *** [libvirt_conf_la-domain_conf.lo] Error 1

If building the libxl domain config fails, cleanup before returning
failure.

Callers should not free death events provided by libxl_evdisable_FOO().

Use consistent parameter names throughout the libxl timeout and fd
event functions.

Commit dfa1e1dd added functions whose definitions do not conform
to the style used in the libxl driver.  Change these functions to
be consistent throughout the driver.

Both 'dir' and 'path' were not free'd on successful return

Fix the leak of vcpupin on failure to allocate cpumask and the leak of
cpumask if we fail to expand vcpupin_list.

Commit '07d1b6b5' added class_id bitmap to virNetworkObj but never freed
it.

In commit c4bbaaf8, caps->arch was checked uninitialized, rendering the
whole check useless.

This patch moves the conditional setting of QEMU_CAPS_NO_ACPI to
qemuCapsInitQMP, and removes the no longer needed exception for S390.

It also clears the flag for all non-x86 archs instead of just S390 in
qemuCapsInitHelp.

Replace the current libxl driver code for managing port
reservations with the new virPortAllocator APIs.

Replace the current QEMU driver code for managing port
reservations with the new virPortAllocator APIs.

Introduce a virPortAllocator for managing TCP port allocations.

The  virDomainObj, qemuAgent, qemuMonitor, lxcMonitor classes
all require a mutex, so can be switched to use virObjectLockable

Since virBufferGetIndent() will check and fail on buf->error, I
removed that check from virBufferAdd() and used the -1 return as the
way to exit.

Check status when attempting to set SO_REUSEADDR flag on outgoing connection
On failure, VIR_WARN(), but continue to connect. This code path is on the
sender side where the setting is just a hint and would only take effect if
the sender is overflowed with TCP connections.  Inability to set doesn't mean
failure to establish a connection.

Commit id ac1c77f0 removed the "os" field in "parallelsDomObj" that
commit id aa296e6c had added and the data is not used by the function.

In virLockSpaceProtocolDispatchNew() the returned value of lockspace from
virLockDaemonFindLockSpace() is overwritten by the virLockSpaceNew() return.
Coverity complains that it's unused.

In virLockSpaceProtocolDispatchCreateLockSpace() lockspace is also overwritten
in a similar manner resulting in the same Coverity message.

After live change of cpu counts, the number of processor threads is
verified. This patch makes use of this approach to check if qemu ignored
the request for cpu hot-unplug and report an appropriate message.

A great many virObject instances require a mutex, so introduce
a convenient class for this which provides a mutex. This avoids
repeating the tedious init/destroy code

Currently all classes must directly inherit from virObject.
This allows for arbitrarily deep hierarchy. There's not much
to this aside from chaining up the 'dispose' handlers from
each class & providing APIs to check types.

Add a 'lxc-enter-namespace' command which accepts a domain name
and then a command + args to run, attached to the container

eg

  virsh -c lxc:/// lxc-enter-namespace demo -- /bin/ps -auxf
