24b74d187c qemu: add memfd source type
Add a new memoryBacking source type "memfd", supported by QEMU (when
the capability is available).

A memfd is a specialized anonymous memory kind. As such, an anonymous
source type could be automatically using a memfd. However, there are
some complications when migrating from different memory backends in
qemu (mainly due to the internal object naming at this point, but
there could be more). For now, it is simpler and safer to simply
introduce a new source type "memfd". Eventually, the "anonymous" type
could learn to use memfd transparently in a separate change.

The main benefits are that it doesn't need to create filesystem files,
and it also enforces sealing, providing a bit more safety.

6e7e965dcd util: storage: Properly parse URIs with missing trailing slash
The URI parser used by libvirt does not populate uri->path if the
trailing slash is missing. The code virStorageSourceParseBackingURI
would then not populate src->path.

As only NBD network disks are allowed to have the 'name' field in the
XML defining the disk source omitted we'd generate an invalid XML which
we'd not parse again.

Fix it by populating src->path with an empty string if the uri is
lacking slash.

As pointed out above NBD is special in this case since we actually allow
it being NULL. The URI path is used as export name. Since an empty
export does not make sense the new approach clears the src->path if the
trailing slash is present but nothing else.

Add test cases now to cover all the various cases for NBD and non-NBD
uris as there was to time only 1 test abusing the quirk witout slash for
NBD and all other URIs contained the slash or in case of NBD also the
export name.

35966308b5 virsh: Fix regression with duplicated error messages
Commit 4f4c3b13 (v3.3) fixed an issue where performing cleanup of
libvirt objects could sometimes lose error messages, by adding code
to copy the libvirt error into last_error prior to cleanup paths.
However, it caused a regression: on other paths, some errors are now
printed twice, if libvirt still remembers in its thread-local
storage that an error was set even after virsh cleared last_error.
For example:

$ virsh -c test:///default snapshot-delete test blah
error: Domain snapshot not found: no domain snapshot with matching name 'blah'
error: Domain snapshot not found: no domain snapshot with matching name 'blah'

Fix things by telling libvirt to discard any thread-local errors at
the same time virsh prints an error message (whether or not the libvirt
error is the same as what is stored in last_error).

Update the virsh-undefine testsuite (partially reverting portions of
commit b620bdee, by removing -q, to more easily pinpoint which commands
are causing which messages), now that there is only one error message
instead of two.

1dbf6222dd virfile: Rework virFileIsSharedFixFUSE
There are couple of things wrong with the current implementation.
The first one is that in the first loop the code tries to build a
list of fuse.glusterfs mount points. Well, since the strings are
allocated in a temporary buffer and are not duplicated this
results in wrong decision made later in the code.

The second problem is that the code does not take into account
subtree mounts. For instance, if there's a fuse.gluster mounted
at /some/path and another FS mounted at /some/path/subdir the
code would not recognize this subdir mount.

a7b4eb7d26 virfiletst: Test virFileIsSharedFS
Introduce some basic test cases for virFileIsSharedFS(). More
will be added later. In order to achieve desired result, mocks
for setmntent() and statfs() need to be invented because the
first thing that virFileIsSharedFS() does is calling the latter.
If it finds a FUSE mount it'll call the former.

The mock might look a bit complicated, but in fact it's quite
simple. The test sets LIBVIRT_MTAB env variable to hold the
absolute path to a file containing mount table. Then, statfs()
returns matching FS it finds, and setmntent() is there just to
replace /proc/mounts with the file the test wants to load.

Adding this test also exposed a bug we have - because we assume
the given path points to a file we cut off what we assume is a
file name to obtain directory path and only then we call
statfs(). This is buggy because the passed path could be already
a mount point.

25456e0470 tests: reintroduce tests for libxl's legacy nested setting
The preferred location for setting the nested CPU flag changed in
Xen 4.10 and is advertised via the LIBXL_HAVE_BUILDINFO_NESTED_HVM

failures against Xen < 4.10 that do not contain the new location.

Commit e94415d5 fixed the failures by only running the tests when
LIBXL_HAVE_BUILDINFO_NESTED_HVM is defined. Since libvirt supports
several versions of Xen that use the old nested location, it is
prudent to test the flag is set correctly. This patch reintroduces
the tests for the legacy location of the nested setting.

In order to use virCgroupNewSelf we need to create all the remaining

      controllers compiled into kernel

    - {name}.self.cgroup represents /proc/self/cgroup, it describes
