qemu is about to deprecate the '-no-hpet' option in favor of configuring
the timer via '-machine'.
Use the QEMU_CAPS_MACHINE_HPET capability to switch to the new syntax
and mask out the old QEMU_CAPS_NO_HPET capability at the same time to
prevent using the old syntax.

The capability represents that qemu accepts the configuration of the
HPET timer via -machine hpet=on/off rather than the
soon-to-be-deprecated '-no-hpet' option.
The capability is detected from 'query-command-line-options' which
recently added the 'hpet' option.

Our secret driver divides secrets into two groups: ephemeral
(stored only in memory) and persistent (stored on disk). Now, the
aim of ephemeral secrets is to define them shortly before being
used and then undefine them. But 'shortly before being used' is a
very vague time frame. And since we default to socket activation
and thus pass '--timeout 120' to every daemon it may happen that
just defined ephemeral secret is gone among with the virtsecretd.
This is no problem for persistent secrets as their definition
(and value) is restored when the virtsecretd starts again, but
ephemeral secrets can't be restored.
Therefore, we could view ephemeral secrets as active objects that
the daemon manages and thus inhibit automatic shutdown (just like
hypervisor daemons do when a guest is running).

In the past, the preferred policy
(VIR_DOMAIN_NUMATUNE_MEM_PREFERRED) required exactly one (host)
NUMA node. This made sense because:
1) the libnuma API - numa_set_preferred() allowed exactly one
node, because
2) corresponding kernel syscall (__NR_set_mempolicy) accepted
exactly one node (for MPOL_PREFERRED mode).
But things have changed since then. Firstly, kernel introduced
new MPOL_PREFERRED_MANY mode (v5.15-rc1~107^2~21) which was then
exposed in libnuma as numa_set_preferred_many() (v2.0.15~24).
Fortunately, libnuma also exposes numa_has_preferred_many() which
returns whether the kernel has support for the new mode (1) or
not (0).
Putting this all together, we can lift our check for sufficiently
new kernel and libnuma.
