46acb0f2b7 Add support for encrypted (qcow) volume creation. 
Supports only virStorageVolCreateXML, not virStorageVolCreateXMLFrom.

Curiously, qemu-img does not need the passphrase for anything to create
an encrypted volume.  This implementation thus does not need to touch
any secrets to work with cooperating clients.  More generic passphrase
handling is added in the next patch.

* src/storage_backend.c: Request encryption when creating qcow/qcow2
  files
* src/storage_backend_disk.c, src/storage_backend_fs.c,
  src/storage_backend_logical.c: Refuse to create volumes with
  encryption params set.

fd06fd1442 storage: Implement CreateVolFrom for logical and disk backend. 
With the previous refactoring, this is a simple process, since the global
'CreateBlockFrom' in storage_backend does all the work.

a500d73ac0 storage: disk: Use capacity, not allocation, when creating volume. 
There isn't any way to dictate allocation when creating disk volumes, so
capacity is the only relevant value.

12a6278135 storage: disk: Fix segfault creating volume without target path 
Remove unneeded target path duplication, which could carelessly dereference
NULL. Make it clear where 'key' is actually filled in.

a9567e09ef Instead of relying solely on polling for /dev devices to appear in libvirt, we 
really should be synchronizing against udev.  This is generally done by a call
to udevsettle, which is exactly what this patch implements for the storage
backends that are likely to create new /dev nodes.  I believe I've read that
even after udevsettle, you are not guaranteed that devices are all the way
created, so we still need the polling in the rest of the sources, but this
should give us a much better chance of things existing as we expect.

17a9e03cd1 Give iSCSI and disk storage backend drivers the 
ability to resolve any kind of volume path to the pool target volume
path.  For instance, if the pool was defined with a
<target><path>/dev/disk/by-id</path></target> section, and one of the
volumes is /dev/disk/by-id/scsi-S_beaf11, then you would be able to
call virStorageVolLookupByPath("/dev/sdc"), and get the correct volume
back.

c0c0fb8eef As suggested by danpb, to fix up the regression caused by last week's VIR_ENUM 
cleanup patch, add a ".defaultFormat" member to .poolOptions.  In
storage_conf.c, if virXPathString(/pool/source/format/@type) returns NULL, then
set the pool type to .defaultFormat; otherwise, lookup the type via
formatFromString.

eeff3cdcbc Add support for detecting the partition table type when scanning 
iSCSI volumes.  This is implemented in the
virStorageBackendUpdateVolInfoFD function, so all future callers will
automatically benefit.  This is a somewhat large patch because the
conversion of the virStorageBackendPartTableTypeToString necessitated
a change to the formatToString and formatFromString function pointers,
which caused fallout in other places in the storage stuff.  The good
news is that most of these callers are now converted over to the
VIR_ENUM_IMPL, which means a lot of redundant code is now gone.

fd52c6ff67 avoid many format string warnings 
Building with --disable-nls exposed many new warnings like these:
virsh.c:4952: warning: format not a string literal and no format ...
util.c:163: warning: format not a string literal and no format arguments
All but one of the following changes add a "%s" argument before
the offending _(...) argument.

This was the only manual change:
* src/lxc_driver.c (lxcVersion): Use %s and strerror(errno)
rather than %m, to avoid a warning from gcc -Wformat-security.

Add "%s" before each warned about format-string-with-no-%-directive:
