The virRandomGenerateWWN() is used solely by nodedev driver to
autogenerate WWNN and WWNP when parsing a nodedev XML. Now, the
idea was (at least during monolithic daemon) that depending on
which hypervisor driver called the nodedev XML parsing (and
virRandomGenerateWWN() under the hood) the corresponding OUI is
used (e.g. "001a4a" for the QEMU driver).
But in era of split daemons things are not that easy. We do not
know which hypervisor driver called us. And there might be no
hypervisor driver at all - users are allowed to connect to
individual drivers directly (e.g. "nodedev:///system").
In this case, we can't use proper OUI. Well, do the next best
thing: pick one (QUMRANET_OUI).

When automatically adding a NUMA node (qemuDomainDefNumaAutoAdd()) the
memory size of the node is computed as:
total_memory - sum(memory devices)
And we have a nice helper for that: virDomainDefGetMemoryInitial() so
it looks logical to just call it. Except, this code runs in post parse
callback, i.e. memory sizes were not validated and it may happen that
the sum is greater than the total memory. This would be caught by
virDomainDefPostParseMemory() but that runs only after driver specific
callbacks (i.e. after qemuDomainDefNumaAutoAdd()) and because the
domain config was changed and memory was increased to this huge
number no error is caught.
So let's do what virDomainDefGetMemoryInitial() would do, but
with error checking.

CVE-2023-3750
'virStoragePoolObjListSearch' explicitly documents that it's returning
a pointer to a locked and ref'd pool that maches the lookup function.
This was not the case as in commit 0c4b391e2a (released in
libvirt-8.3.0) the code was accidentally converted to use 'VIR_LOCK_GUARD'
which auto-unlocked it when leaving the scope, even when the code was
originally "leaking" the lock.
Revert the corresponding conversion and add a comment that this function
is intentionally leaking a locked object.

Historically we wanted to check if logind was actually running, not
merely activatable, because on systems where systemd is installed,
but the OS is booted into non-systemd init, we want to fallback to
pm-utils.
Requiring logind to be running, however, forces us to serialize libvirtd
startup on startup of logind which is undesirable. We can relax this
dependancy if we check whether systemd itself is running, which implies
that logind will activated when we need it.

Since systemd 240, all services get an open file hard limit of
500k, and a soft limit of 1024. This limit means apps are safe
to use select() by default which is limited to 1024 FDs. Apps
which don't use select() are expected to simply set their soft
limit to match the hard limit during startup.
With our current unit file settings we've been effectively
reducing the max open files we have on most modern systems.
