Export string conversion from and to the virStorageVolType enum.

When attempting to backport gluster pools to an older versoin
where there is no VIR_STRDUP, I got a crash from calling
strdup(,NULL). Rather than relying on the current else branch
safely doing nothing when there is no fd, it is easier to just
skip it. While at it, there's no need to explicitly set
perms.label to NULL after a VIR_FREE().

The virsh command 'domxml-to-native' (virConnectDomainXMLToNative())
converts all network devices to "type='ethernet'" in order to make it
more likely that the generated command could be run directly from a
shell (other libvirt network device types end up referencing file
descriptors for tap devices assumed to have been created by libvirt,
which can't be done in this case).

During this conversion, all of the netdev parameters are cleared out,
then specific items are filled in after changing the type. The MAC
address was not one of these preserved items, and the result was that
mac addresses in the generated commandlines were always
00:00:00:00:00:00.

This patch saves the mac address before the conversion, then
repopulates it afterwards, so the proper mac addresses show up in the
commandline.

When looking for numad with AC_PATH_PROG, include /usr/sbin in

Commit 348b4e25 introduced a potential problem (thankfully not
in any release): we are attempting to use virFileReadHeaderFD()
on a file that was opened with O_NONBLOCK.  While this
shouldn't be a problem in practice (because O_NONBLOCK
typically doesn't affect regular or block files, and fifos and
sockets cannot be storage volumes), it's better to play it safe
to avoid races from opening an unexpected file type while also
avoiding problems with having to handle EAGAIN while read()ing.

Since the label is at the beginning of the loop, this has the same effect.

With some authentication mechanism (PLAIN for example), sasl_client_start()
can return SASL_OK, which translates to virNetSASLSessionClientStart()
returning VIR_NET_SASL_COMPLETE.
cyrus-sasl documentation is a bit vague as to what to do in such situation,
but upstream clarified this a bit in
http://asg.andrew.cmu.edu/archive/message.php?mailbox=archive.cyrus-sasl&msg=10104

When we got VIR_NET_SASL_COMPLETE after virNetSASLSessionClientStart() and
if the remote also tells us that authentication is complete, then we should
end the authentication procedure rather than forcing a call to
virNetSASLSessionClientStep(). Without this patch, when trying to use SASL
PLAIN, I get:
error :authentication failed : Failed to step SASL negotiation: -1
(SASL(-1): generic failure: Unable to find a callback: 32775)

This patch is based on a spice-gtk patch by Dietmar Maurer.

virNetSASLSessionClientStep logs the data that is going to be passed to
sasl_client_step as input data. However, it tries to log it as a string,
while there is no guarantee that this data is going to be nul-terminated.
This leads to this valgrind log:

The array of sasl_callback_t callbacks which is passed to sasl_client_new()
must be kept alive as long as the created sasl_conn_t object is alive as
cyrus-sasl uses this structure internally for things like logging, so
the memory used for callbacks must only be freed after sasl_dispose() has
been called.

Putting together pieces from previous patches, it is now possible
for 'virsh vol-dumpxml --pool gluster volname' to report metadata
about a qcow2 file stored on gluster.  The backing file is still
treated as raw; to fix that, more patches are needed to make the
storage backing chain analysis recursive rather than halting at
a network protocol name, but that work will not need any further
calls into libgfapi so much as just reusing this code, and that
should be the only code outside of the storage driver that needs
any help from libgfapi.  Any additional use of libgfapi within
libvirt should only be needed for implementing storage pool APIs
such as volume creation or resizing, where backing chain analysis
should be unaffected.

In the 'directory' and 'netfs' storage pools, a user can see
both 'file' and 'dir' storage volume types, to know when they
can descend into a subdirectory.  But in a network-based storage
pool, such as the upcoming 'gluster' pool, we use 'network'
instead of 'file', and did not have any counterpart for a
directory until this patch.  Adding a new volume type
'network-dir' is better than reusing 'dir', because it makes
it clear that the only way to access 'network' volumes within
that container is through the network mounting (leaving 'dir'
for something accessible in the local file system).

Actually put gfapi to use, by allowing the creation of a gluster
pool.  Right now, all volumes are treated as raw and directories
are skipped; further patches will allow peering into files to
allow for qcow2 files and backing chains, and reporting proper
volume allocation.  This implementation was tested against Fedora
19's glusterfs 3.4.1; it might be made simpler by requiring a
higher minimum, and/or require more hacks to work with a lower
minimum.

We support gluster volumes in domain XML, so we also ought to
support them as a storage pool.  Besides, a future patch will
want to take advantage of libgfapi to handle the case of a
gluster device holding qcow2 rather than raw storage, and for
that to work, we need a storage backend that can read gluster
storage volume contents.  This sets up the framework.

Note that the new pool is named 'gluster' to match a
<disk type='network'><source protocol='gluster'> image source
already supported in a <domain>; it does NOT match the
<pool type='netfs'><source><target type='glusterfs'>,
since that uses a FUSE mount to a local file name rather than
a network name.

This and subsequent patches have been tested against glusterfs
3.4.1 (available on Fedora 19); there are likely bugs in older
versions that may prevent decent use of gfapi, so this patch
enforces the minimum version tested.  A future patch may lower
the minimum.  On the other hand, I hit at least two bugs in
3.4.1 that will be fixed in 3.5/3.4.2, where it might be worth
raising the minimum: glfs_readdir is nicer to use than
glfs_readdir_r [1], and glfs_fini should only return failure on
an actual failure [2].

This reverts commit 6b90d742.

The original problem was that libvirt_virConnectGetCPUModelNames

to list it in the skip_impl list, and not delete the manually
written code entirely.

This nested job is canceled by the first ExitMonitor call (even though
it was not created by the corresponding EnterMonitor call), and
again in qemuMigrationPrepareAny if qemuProcessStart failed.

Restarting an active libvirt-guests.service is the equivalent of
doing:

/usr/libexec/libvirt-guests.sh stop
/usr/libexec/libvirt-guests.sh start

Which in a default configuration will managedsave every running VM,
and then restore them. Certainly not something we should do every
time the libvirt-client RPM is updated.

Just drop the try-restart attempt, I don't know what purpose it
serves anyways.

As virt-login-shell is an SUID binary, we should restrict its usage to
just the users chosen by an administrator to use virt-login-shell as
their login shell. This can easily be done by making the binary
executable only by users from a new virtlogin group.
