53393c894d Look at /etc/login.defs for the system_max_[ug]id values
It makes little sense to make the boundary between systemd and user guids
configurable. Nevertheless, a completely fixed compile-time define is not
enough in two scenarios:
- the systemd_uid_max boundary has moved over time. The default used to be
  500 for a long time. Systems which are upgraded over time might have users
  in the wrong range, but changing existing systems is complicated and
  expensive (offline disks, backups, remote systems, read-only media, etc.)
- systems are used in a heterogenous enviornment, where some vendors pick
  one value and others another.
So let's make this boundary overridable using /etc/login.defs.

Fixes #3855, #10184.

fbccb980e5 random-util: Add an environment variable to disable RDRAND.
SYSTEMD_RDRAND=0 will prevent using RDRAND even on systems whose CPUID claims
to support it. All other values have no effect.

4c8e5f442b meson: make "developer" mode the default
This means that the dbus doc consistency checks will be enabled by default,
including in the CI. I think that will work better than current state where
people do not enable them and them follow-up patches for the docs like the
parent commit must be had.

9df2cdd8ec exec: SystemCallLog= directive
With new directive SystemCallLog= it's possible to list system calls to be
logged. This can be used for auditing or temporarily when constructing system
call filters.

4e39995371 core: introduce ProtectProc= and ProcSubset= to expose hidepid= and subset= procfs mount options
Kernel 5.8 gained a hidepid= implementation that is truly per procfs,
which allows us to mount a distinct once into every unit, with
individual hidepid= settings. Let's expose this via two new settings:
ProtectProc= (wrapping hidpid=) and ProcSubset= (wrapping subset=).

172ad053ff mkosi: Keep mkosi.default out of the repository.
Defaulting to fedora makes it a pain to override mkosi.default
point to one of the other mkosi settings files. Instead, have
every developer manually add the symlink to his distro
of choice and don't commit the symlink to the repository by
putting it in the .gitignore.

38ccb55731 nss-mymachines: drop support for UID/GID resolving
Now that we make the user/group name resolving available via userdb and
thus nss-systemd, we do not need the UID/GID resolving support in
nss-mymachines anymore. Let's drop it hence.

We keep the module around, since besides UID/GID resolving it also does
hostname resolving, which we care about. (One of those days we should
replace that by some Varlink logic between
nss-resolve/systemd-resolved.service too)

The hooks are kept in the NSS module, but they do not resolve anything
anymore, in order to keep compat at a maximum.

sssd people don't like enumeration and for some other cases it's not

container/userns UID/GID ranges.

Hence, let's make enumeration optional.

c0bde0d240 user-record: rename JSON field "pkcs11Pin" to "tokenPin"
We'd like to use it for FIDO2 tokens too, and the concept is entirely
generic, hence let's just reuse the field, but rename it. Read the old
name for compatibility, and treat the old name and the new name as
identical for most purposes.
