This adds four options for virsh command attach-disk.

--cache option allows user to specify cache mode of disk device
from virsh command line when attaching a disk device.

--serial option allows user to specify serial string of disk device
from virsh command line when attaching a disk device.

--shareable option allows user to specify whether the disk device is
shareable between domains when attaching a disk device from virsh
command line.

--address option allows user to specify address of disk device when
attaching a disk device.

If the server succesfully validates the client cert, it will send
back a single byte, under TLS. If it fails, it will close the
connection. In this case, we were just reporting the standard
I/O error. The original RPC code had a special case hack for the
GNUTLS_E_UNEXPECTED_PACKET_LENGTH error code to make us report
a more useful error message

* src/rpc/virnetclient.c: Return ENOMSG if we get
  GNUTLS_E_UNEXPECTED_PACKET_LENGTH
* src/rpc/virnettlscontext.c: Report cert failure if we
  see ENOMSG

Many volume operations will fail if the volume in question is being
allocated.  These operations were returning VIR_ERR_INTERNAL_ERROR
when they should be returning VIR_ERR_OPERATION_INVALID.

This patch adds the --current option to "virsh setvcpus"
command. Currently "virsh setvcpus" command supports
"--live" and "--config" , but "--current" option.
From view of consistency, it's reasonable to support
"--current" option too.

When --current is specified, it affects a "current"
domain.

This patch extends virDomainSetVcpusFlags API to support
VIR_DOMAIN_AFFECT_CURRENT flag.

Now because most APIs accept VIR_DOMAIN_AFFECT_CURRENT flags,
virDomainSetVcpusFlags API should also do.

Rather than trying to clean up the ssh child ourselves, and risk
subtle differences from the socket creation error path, we can
just use the new APIs.

* src/rpc/virnetsocket.c (virNetSocketFree): Use new function.

By requesting the pid in virCommandRunAsync, fdstream was claiming
that it would manually wait for the process.  But on the failure
path, the child process was being leaked.

* src/fdstream.c (virFDStreamOpenFileInternal): Auto-reap child.

When using virCommandRunAsync and saving the pid for later, it
is useful to be able to reap that pid in the same way that it
would have been auto-reaped by virCommand if we had passed
NULL for the pid argument in the first place.

* src/util/command.c (virPidWait, virPidAbort): New functions,
created from...
(virCommandWait, virCommandAbort): ...bodies of these.
(includes): Drop duplicate <stdlib.h>.  Ensure that our pid_t
assumptions hold.
(virCommandRunAsync): Improve documentation.

* src/libvirt_private.syms: Export them.
* docs/internals/command.html.in: Document them.

In the Ubuntu development release we recently got a new udev that
moves /var/run to /run, /var/lock to /run/lock and /dev/shm to /run/shm.
This change in udev requires updating the apparmor security driver in
libvirt[1].

Attached is a patch that:
 * adjusts src/security/virt-aa-helper.c to allow both
LOCALSTATEDIR/run/libvirt/**/%s.pid and /run/libvirt/**/%s.pid. While
the profile is not as precise, LOCALSTATEDIR/run/ is typically a symlink
to /run/ anyway, so there is no additional access (remember that
apparmor resolves symlinks, which is why this is still required even
if /var/run points to /run).
 * adjusts example/apparmor/libvirt-qemu paths for /dev/shm

Use better suited error code and avoid NULL in error messsage
as *privP->session->error_description can be NULL.

Without this patch, the make rule in a VPATH build was trying to
invoke ../../docs/../../docs/todo.pl, which didn't exist.

$(srcdir) in GNU make VPATH situations.

We disable some drivers when building without libvirtd in configure,
but we do not do the same thing in libvirt.spec. It may break rpm
building without libvirtd.

Getting metadata on storage allocates a memory (path) which need to
be freed after use otherwise it gets leaked. This means after use of
virStorageFileGetMetadataFromFD or virStorageFileGetMetadata one
must call virStorageFileFreeMetadata to free it. This function frees
structure internals and structure itself.

When qemuMonitorCloseFileHandle is called in error path, we need to
preserve the original error since a possible further error when running
closefd monitor command is not very useful to users.

When creating new qemu process we saved domain status XML only after the
process was fully setup and running. In case libvirtd was killed before
the whole process finished, once libvirtd started again it didn't know
anything about the new process and we end up with an orphaned qemu
process. Let's save the domain status XML as soon as we know the PID so
that libvirtd can kill the process on restart.

The compiler might optimize based on our declaration that something
is unused.  Putting that declaration in the header risks getting
out of sync with the actual implementation, so it belongs better
only in the .c files.  We were mostly compliant, and a new syntax
check will help us in the future.

* cfg.mk (sc_avoid_attribute_unused_in_header): New syntax check.
* src/nodeinfo.h (nodeGetCPUStats, nodeGetMemoryStats): Delete
attribute already present in .c file.

The last patch breaks make check for two reasons. First, it reverses the
condition but leaves default level unchanged, so instead of not printing
anything but errors before the patch it now prints all debug messages by
default. Second, you forgot to change -d5 option passed to virsh in
tests/virsh-optparse to -d0; the script wants to see all debug messages.

Aligning loglevel values of virsh to that of libvirt.
"DEBUG"=0 loglevel, when specified through commandline or
env variable, should log all the messages. "ERROR=4"
should log only error messages.
