b5e267e8c5 virsh: Simplify @flags handing in cmdSetmem() and cmdSetmaxmem()
What code tries to achieve is that if no flags were provided to
either 'setmem' or 'setmaxmem' commands then the old (no flags)
API is called to be able to communicate with older daemons.
Well, the code can be simplified a bit.

Note that with this change the old no flag version of APIs is
used more often. Previously if --current argument was given it
resulted in *Flags() version to be called even though it is not
necessary - VIR_DOMAIN_AFFECT_CURRENT is implied.

Therefore, this change in fact allows virsh to talk with broader
set of daemons. No other user visible changes were made.

f9f81f1c8f conf: replace VIR_FREE() with g_free() in vir*Free() functions
This patch takes on one set of examples of unnecessary use of
VIR_FREE() when g_free() is adequate - it modifies only vir*Free()
functions within the conf directory that take a single pointer and
free the object pointed to by that argument before returning. The
modification is to replace VIR_FREE() with g_free() for the object
itself *and* for all subordinate chunks of memory pointed to by that
object.

(NB: there are other functions that VIR_FREE subordinate memory of
objects that end up being freed before return (also sometimes with
VIR_FREE); I am purposefully ignoring those to reduce scope and focus
on a sub class where the pointlessness is obvious.)

45b2912c71 util: rename virStorageEncryptionInfoDefFree()
usually a function call vir*Free() will take a single pointer to an
object as its argument, and will then free all resources associated
with that object, including the object
itself. virStorageEnctyptionInfoDefFree() doesn't do that - it frees
all the subordinate resources of the ojbect, but doesn't free the
object itself; usually a function like that is called
vir*Clear(). Let's rename this function to not be misleading.

8fb0b08762 hostdevmgr: remove unneeded oldStateDir
Back in commit 2c71d3826, which appeared in libvirt-1.2.3 in April
2014, the location used to store saved MAC addresses and vlan tags of
SRIOV VFs was changed from /var/run/libvirt/qemu to
/var/run/libvirt/hostdevmgr. For backward compatibility the code was
made to continue looking in the old location for the files when it
didn't find them in the new location.

It's now been 6 years, and even if there was somebody still running
libvirt-1.2.3 on their system, that system would now be out of support
for libvirt, so there would be no way for them to upgrade to a new
libvirt that no longer looks in  "oldStateDir" for the files. So
let's no longer look in "oldStateDir" for the files!

65ce8a424f log error if virConnectCacheOnceInit() fails
virGetConnectNetwork() calls
 virGetConnectGeneric(), which calls
  virConnecCacheInitialize(), which is actually a call (only once) to
   virConnectCacheOnceInit() which calls
    virThreadLocalInit() several times, which calls
     pthread_key_create()

If pthread_key_create() fails, it (of course) doesn't log an error
(because it's not a part of libvirt), nor does any other function on
the call chain all the way up to virGetConnectNetwork(). But none of
the callers of virGetConnectNetwork() log an error either, so it is
possible that an API could fail due to virGetConnectNetwork() failing,
but would only log "an error was encountered, but the cause is
unknown. Deal with it."  (paraphrasing).

(In all likelyhood, virConnectCacheOnceInit() is going to be called at
some earlier time, and almost certainly pthread_key_create() will
never fail (and if it does, the user will have *much* bigger problems
than an obtuse error message from libvirt)).

31d1835428 virfile: workaround for when posix_fallocate() is not supported by FS
posix_fallocate() might be not supported by a filesystem, for example,
it's not supported by ZFS. In that case it fails with
return code 22 (EINVAL), and thus safezero_posix_fallocate() returns -1.

As safezero_posix_fallocate() is the first function tried by safezero()
and it tries other functions only when it returns -2, it fails
immediately without falling back to other methods, such as
safezero_slow().

Fix that by returning -2 if posix_fallocate() returns EINVAL, to give
safezero() a chance to try other functions.

35d5b26aa4 rpm: disable netcf for the interface driver in rpm build on new targets
libvirt.spec currently adds a hardcoded -Dnetcf=enabled to the meson
commandline, so just setting the default in the meson.build file won't
have any effect for rpm builds - it will be overridden.

This patch changes the meson commandline in the spec file from
hardcoded -Dnetcf=enabled to %{arg_netcf}, which is itself set
according to the value of %{with_netcf}; and *that* is normally set
according to the distro release of the build target (1 for Fedora >=
34 and RHEL >= 9, 0 otherwise), but can be manually overridden by
adding "-without netcf" to the rpmbuild commandline.

Along with being used to determine what arg to pass to meson,
%{with_netcf} is also checked when deciding on whether or not to add
netcf build time / install time dependencies ("Requires: netcf-libs"
and "BuildRequires: netcf-devel")

06169a115d build: support explicitly disabling netcf
placing "-Dnetcf=disabled" on the meson commandline was ignored,
meaning that even with that option the build would get WITH_NETCF if
the netcf-devel package was found - the only way to disable it was to
uninstall netcf-devel.

This patch adds the small bit of logic to check the netcf meson
commandline option (in addition to whether netcf-devel is installed)
before defining WITH_NETCF.

b0264e9404 virpci.c: simplify virPCIDeviceNew() signature
The current virPCIDeviceNew() signature, receiving 4 uints in sequence
(domain, bus, slot, function), is not neat.

We already have a way to represent a PCI address in virPCIDeviceAddress
that is used in the code. Aside from the test files, most of
virPCIDeviceNew() callers have access to a virPCIDeviceAddress reference,
but then we need to retrieve the 4 required uints (addr.domain, addr.bus,
addr.slot, addr.function) to satisfy virPCIDeviceNew(). The result is
that we have extra verbosity/boilerplate to retrieve an information that
is already available in virPCIDeviceAddress.

A better way is presented by virNVMEDeviceNew(), where the caller just
supplies a virPCIDeviceAddress pointer and the function handles the
details internally.

This patch changes virPCIDeviceNew() to receive a virPCIDeviceAddress
pointer instead of 4 uints.

  a) this check can be done in the function itself (making all

The qemuDomainAuthorizedSSHKeysSet method marked the object
as an autoptr while also have some code paths that will call
virDomainObjEndAPI. As a result the object will be released
but not unlocked in error paths.

69977ff105 qemu: Avoid crash in qemuStateShutdownPrepare() and qemuStateShutdownWait()
If QEMU driver fails to initialize for whatever reason (it can be
as trivial as a typo on qemu.conf), the control jumps to error
label in qemuStateInitialize() where qemuStateCleanup() is called
which frees the driver. But the daemon then asks drivers to
prepare for shutdown, which in case of QEMU driver is implemented
in qemuStateShutdownPrepare(). In here, the driver is
dereferenced but since it was freed earlier, the pointer is NULL
which leads to instant crash.

Solution is simple - just check if qemu_driver is not NULL. But
doing so only in qemuStateShutdownPrepare() would push the
problem down to virStateShutdownWait(), well
qemuStateShutdownWait(). Therefore, duplicate the trick there
too.

ab82d41f41 tests: storage: Replace index testing in testStorageLookup
Test the actual index in the returned virStorageSource rather than the
parsed one. Some tests need to be adapted as they were on failed lookup.

8fd72501c8 virStorageSourceChainLookup: Handle names like 'vda[4]' internally
All callers of this function called virStorageFileParseChainIndex
before. Internalize the logic of that function to prevent multiple calls
and passing around unnecessary temporary variables.

This is achieved by calling virStorageFileParseBackingStoreStr and using
it to fill the values internally.

49c89fa70e test: storage: Remove double testing in testStorageLookup
The function attempts two calls to virStorageSourceChainLookup to see
whether the function handles NULL correctly. This isn't very useful and
additionally upcoming patch will remove the 'idx' parameter thus the
test becomes obsolete. Remove it.
