virsh snapshot-create-as supports 'file' storage type in --diskspec by default.
But it doesn't support 'block' storage type in the virshParseSnapshotDiskspec().
So if a snapshot on a block device (e.g. LV) was created, the type of
current running storage source in dumpxml is inconsistent with the actual
backend storage source. It will check file-system type mismatch failed
and return an error message of 'Migration without shared storage is unsafe'
when VM performs a live migration after this snapshot.
Considering virsh has to be able to work remotely that recognizing a block device
by prefix /dev/ or by stat() may be not suitable, so adding a "stype" field
for the --diskspec string which will be either "file" or "block".
e.g. --diskspec vda,snapshot=external,driver=qcow2,stype=block,file=/dev/xxx.

The docs talked about an active snapshot when they meant an active
domain; they also claimed the flag was a no-op for hypervisors with no
snapshot metadata even though the flag is currently rejected as
unrecognized for hypervisors with no snapshot support at all. A later
patch may teach more drivers to ignore the flag as a no-op, but that
shouldn't conflict with the wording chosen here (since a new client
talking to an old server still runs into the same issue, even if a
newer server becomes more tolerant).

The virConnectGetType() method has an unfortunate signature, returning a
static string that must not be freed by the caller. The remote driver,
however, gets this string dynamically over an RPC call, which raised a
design discussion on the mailing list. Eventually the problem was
resolved by having the remote driver cache the returned string
internally and free it when the connection was closed.
The link to the mailing list is thus talking about a problem that does
not actually exist in the final implementation, and at best serves to
confuse the reader into thinking there might be a memory leak.

Neither the sasl_client_init or sasl_server_init methods are even
remotely threadsafe. They do a bunch of one-time initialization and
merely use a simple integer counter to avoid repeated work, not even
using atomic increment/reads on the counter. This can easily race in a
threaded program. Protect the calls using a virOnce initializer function
which is guaranteed threadsafe at least from libvirt's POV.
If the application using libvirt also uses another library that makes
use of SASL then the race still exists. It is impossible to fix that
fully except in SASL code itself.

The qemusecuritytest is failing on FreeBSD 11/12, reporting that files
are not correctly restored. Debugging code printfs show that the
virFileGetXAttrQuiet mock is returning 0, but the virFileGetXAttr
function is seeing -1 as the return value.
Essentially there appears to be some kind of optimization between the
real virFileGetXAttrQuiet and the real virFileGetXAttr, which breaks
when we mock virFileGetXAttrQuiet. Rather than trying to figure out
how to avoid this, it is simpler to just mock virFileGetXAttr too
since it is very short code.
