3401e208ab qemu: Don't mangle the storage format for type='dir'
Our backing probing code handles directory file types properly in
virStorageFileGetMetadataRecurse(), by that I mean it leaves them
alone.  However its caller, the virStorageFileGetMetadata() resets the
type to raw before probing, without even checking the type.  We need
to special-case TYPE_DIR in order to achieve desired results.

Also, in order to properly test this, we need to stop resetting format
of volumes in tests for TYPE_DIR (probably the reason why we didn't
catch that and why the test data didn't need to be modified).

5102be52d8 conf: Properly truncate wide character names in virDomainObjGetShortName
We always truncated the name at 20 bytes instead of characters.  In
case 20 bytes were in the middle of a multi-byte character, then the
string became invalid and various parts of the code would error
out (e.g. XML parsing of that string).  Let's instead properly
truncate it after 20 characters instead.

We cannot test this in our test suite because we would need to know
what locales are installed on the system where the tests are ran and
if there is supported one (most probably there will be, but we cannot
be 100% sure), we could initialize gettext in qemuxml2argvtest, but
there would still be a chance of getting two different (both valid,
though) results.

In order to test this it is enough to start a machine with a name for
which trimming it after 20 bytes would create invalid sequence (e.g.
1234567890123456789č where č is any multi-byte character).  Then start
the domain and restart libvirtd.  The domain would disappear because
such illegal sequence will not go through the XML parser.  And that's
not a bug of the parser, it should not be in the XML in the first
place, but since we don't use any sophisticated formatter, just
mash some strings together, the formatting succeeds.

b988f794e3 daemon: logging: Fix --verbose option being ignored by the daemon
Commit 94c465d0 refactored the logging setup phase but introduced an
issue, where the daemon ignores verbose mode when there are no outputs
defined and the default must be used. The problem is that the default
output was determined too early, thus ignoring the potential '--verbose'
option taking effect. This patch postpones the creation of the default
output to the very last moment when nothing else can change. Since the
default output is only created during the init phase, it's safe to leave
the pointer as NULL for a while, but it will be set eventually, thus not
affecting runtime.
Patch also adjusts both the other daemons.

1f43393283 qemu: Handle host devices not being available better
We can't retrieve the isolation group of a device that's not present
in the system. However, it's very common for VFs to be created late
in the boot, so they might not be present yet when libvirtd starts,
which would cause the guests using them to disappear.

Moreover, for other architectures and even ppc64 before isolation
groups were introduced, it's considered perfectly fine to configure a
guest to use a device that's not yet (or no longer) available to the
host, with the obvious caveat that such a guest won't be able to
start before the device is available.

In order to be consistent, when a device's isolation group can't be
determined fall back to not isolating it rather than erroring out or,
worse, making the guest disappear.

d9fc08d103 vmx: do not treat controllers as implicit devices
When parsing the config, we look for the SCSI controllers one by one,
remembering their models, then let virDomainDefAddImplicitDevices
add them if any SCSI disk is using them.

Since these controllers are not really implicit (they are present
in the source config), add them explicitly.

This patch maintains the behavior of not adding a controller
if it was present in the config, but no disk was using it.

This also resolves the memory leak of virVMXParseConfig overwriting
the video device added by calling virDomainDefAddImplicitDevices
before the parsing is finished.
