Most of our kernel cmdline options use underscores as word separators in
kernel cmdline options, but there were some exceptions. Let's fix those,
and also use underscores.
Since our /proc/cmdline parsers don't distinguish between the two
characters anyway this should not break anything, but makes sure our own
codebase (and in particular docs and log messages) are internally
consistent.
TPM 1.2 is obsolete, and doesn't really provide much security guarantees
given it's build around SHA1 which is not up to today's standards.
The rest of systemd's TPM codebase never supported TPM 1.2 hence let's
drop this partial support in sd-stub too. It has created problems after
all (sd-stub reported the measuements and userspace assumed these were
for TPM2), without bringing any benefits (given that the measurements we
make are not consumed by us anyway, unlike those for TPM 2.0)
let's cut off this old support.
This is in preparation for https://github.com/systemd/systemd/pull/30360 to be
merged in a future release. As described there:
nscd is known to be racy [1] and it was already deprecated and later dropped
in Fedora a while back [1,2]. We don't need to support obsolete stuff in
systemd, and the cache in systemd-resolved provides a better solution anyway.

[2] https://fedoraproject.org/wiki/Changes/RemoveNSCD
Note that our "support" is only the signal to flush the cache that we send at
various points. Nscd itself may still exist, dropping it is a decision to be
made in glibc.
A non-breaking space is used between "PCR" and the number. I did
search&replace on the whole file, so that when people select&paste
later, they are more likely to use the same format.
Linux's Control Group v2 interfaces exposes memory.peak, which contains the
"max memory usage recorded for the cgroup and its descendants since the
creation of the cgroup."
This commit adds a new property "MemoryPeak" for units and makes "systemctl
show" display this value if it is available.
Fixes#29878.
