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

fix this problem by checking if selinuxfs is mounted
in host before we try to create dir /sys/fs/selinux.

Commit 509eb51e added lxc_protocol.x; but without the initial
checkin of src/lxc_protocol-structs, 'make check' would fail for
anyone with pdwtags installed:
make[3]: *** No rule to make target `lxc_protocol-structs', needed by `check-protocol'.  Stop.

* src/lxc_protocol-structs: New file.

The virDomainLxcOpenNamespace method needs to open every file
in /proc/$INITPID/ns and return the open file descriptor to the
client application.

Make cpuset local to the while loop and free it once done with it each
time through the loop.  Add a sa_assert() to virBitmapParse() to keep Coverity
from believing there could be a negative return and possible resource leak.

Added some messaging to indicate possible failure from virXPathULongLong()
as well

Commit-id 'afc4631b' added the regfree(reg) to free resources alloc'd
during regcomp; however, reg still needed to be VIR_FREE()'d. The call
to regfree() also didn't account for possible NULL value.  Reformatted
the call to be closer to usage.

Commit c308a9ae was incomplete; it resolved the configure failure,
but not a later build failure.

* src/util/virnetdevbridge.c: Include pre-req header.
* configure.ac (AC_CHECK_HEADERS): Prefer standard in.h over
non-standard ip6.h.

* tools/virsh.pod: Fix typo.

Commit 907a39e7 missed adding the WITH_ATTR around #include <attr/xattr.h>
resulting in a build failure:

  CC     libsecurityselinuxhelper_la-securityselinuxhelper.lo
  securityselinuxhelper.c:27:24: fatal error: attr/xattr.h: No such file or directory
  compilation terminated.
  make[2]: *** [libsecurityselinuxhelper_la-securityselinuxhelper.lo] Error 1

  make[1]: *** [all-recursive] Error 1
  make[1]: Leaving directory `/home/jferlan/libvirt.work'
  make: *** [all] Error 2

Make sure we override both the raw and non-raw stubs in
securityselinuxhelper.c. Also add diagnostics if
securityselinuxlabeltest fails a test item

Some places missed the conversion from LIBCURL_{CFLAGS,LIBS} to
CURL_{CFLAGS,LIBS}, and a part of curl check was left in
configure.ac instead of m4/virt-curl.m4 by mistake

I got this scary warning during ./configure on rawhide:

* configure.ac (AC_CHECK_HEADERS): Provide struct in6_addr, since
linux/if_bridge.h uses it without declaring it.

Mark virDomainLxcEnterNamespace as skipped in python binding
and remove reference to lxcDomainOpenNamespace which doesn't
arrive until a later patch

I noticed this typo while configuring on a freshly-installed machine.

* m4/virt-udev.m4: Correct pciaccess name.
