As advertised in previous commit, there are three APIs that might
run for quite some time (because they read/write data from/to a
volume) and these three are: downloadVol, uploadVol, wipeVol.
Release pool object lock and reacquire it later to allow more
concurrency.

There are few operations in the storage driver that read/write
data onto volumes. Such operations can take very long time to
finish. During that time the storage pool object is locked which
has bad performance impacts (other threads can't fetch its XML
for instance). This commit prepares the storage driver for
releasing the lock during those operations (downloadVol,
uploadVol, wipeVol).

Even though we do some checking it is not as thorough as it
should be. We already have virStoragePoolObjIsDuplicate but the
way we use it is a typical TOCTOU. Imagine two threads trying to
define two pools with the same name but different UUIDs. With the
current code neither of them finds a duplicate and thus proceed
to virStoragePoolObjAssignDef where only names are compared.
Therefore both threads succeed which is obviously wrong.
We should check for duplicates where we care for them.

When introducing this check back in 4ad54a417a my mindset was
that if an element is missing in update XML then user is
requesting for removal of the corresponding setting. For
instance, if <bandwidth/> is not present in update XML any QoS
previously set on <interface/> is cleared out. Well this
assumption is correct but only to some extent.
Turns out, we have some users who when updating path to ISO
image construct very minimalistic disk XML and pass it to device
update API. Such XML is lacking a lot of information, and alias
is one of them. This triggers error in
virDomainDefCompatibleDevice() because we think that user is
requesting to remove the alias. Well, they are not.

Commit 6534b3c4 tried to raise an error when there is no numa
nodes by setting access='shared' in the domain config, but added
a helper called from qemuDomainDeviceDefValidate instead of a
helper called from qemuDomainDefValidate for XML:
<memoryBacking>
<hugepages/>
<access mode='shared'/>
</memoryBacking>
Since there are no memory devices in the test XML, there would
be no validation failure, but the test added was still failing.
Investigating that it turns out that unnecessary XML elements
were causing the failure (no need for <video>, <graphics>,
<pm>, usb controller model "piix3-uhci", disk attribute for
"discard='unmap'", <serial>, <console>, <channel> and a
memballoon model). Removing all those before moving the method
caused the test to succeed.
So this patch moves the validation to the right place and
removes all the unnecessary XML pieces that were causing
a false validation failure.

The reason of broken build was that centos and rhel use older version of
glibc. These versions of glibc on these platforms cannot work with newer
unicodes, thus causing functions iswprint() and wcwidth() return
unexpected values causing the vshtabletest to fail. Therefore, let's
replace the new unicode characters causing issues with some older ones
to fix the test suite, as the issue would still persist during runtime.

If @vm has flagged as "to be removed" virDomainObjListFindByNameLocked
returns NULL (although the definition actually exists). Therefore, the
possibility exits that "virHashAddEntry" will raise the error
"Duplicate key" => virDomainObjListAddObjLocked fails =>
virDomainObjEndAPI(&vm) is called and this leads to a freeing of @def
since @def is already assigned to vm->def. But actually this leads to
a double free since the common usage pattern is that the caller of
virDomainObjListAdd(Locked) is responsible for freeing @def in case of
an error.
Let's fix this by setting vm->def to NULL in case of an error.
