The services systemd-networkd, systemd-resolved, and systemd-timesyncd
enable DynamicUsers= and have bus interfaces. Unfortunately, these
has many problems now. Let us create the relevant users, at least,
tentatively.
Fixes#9503.
The configuration option was called -Dresolve, but the internal define
was …RESOLVED. This options governs more than just resolved itself, so
let's settle on the version without "d".
As kdbus won't land in the anticipated way, the bus-proxy is not needed in
its current form. It can be resurrected at any time thanks to the history,
but for now, let's remove it from the sources. If we'll have a similar tool
in the future, it will look quite differently anyway.
Note that stdio-bridge is still available. It was restored from a version
prior to f252ff17, and refactored to make use of the current APIs.
Let's add an extra-safety net and change UID/GID to the "systemd-coredump" user when processing coredumps from system
user. For coredumps of normal users we keep the current logic of processing the coredumps from the user id the coredump
was created under.

./configure --enable/disable-kdbus can be used to set the default
behavior regarding kdbus.
If no kdbus kernel support is available, dbus-dameon will be used.
With --enable-kdbus, the kernel command line option "kdbus=0" can
be used to disable kdbus.
With --disable-kdbus, the kernel command line option "kdbus=1" is
required to enable kdbus support.
Choose which system users defined in sysusers.d/systemd.conf and files
or directories in tmpfiles.d/systemd.conf, should be provided depending
on comile-time configuration.
