The original idea of systemd.pc was to contain arch-independent system
and systemd information. By exposing libdir as part of the fields (added
in eb39a6239c), it started to carry
arch-dependent data, thus breaking multilib systems. It was then moved
to pkgconfiglibdir to deal with this (in
aec432c613), but actually the right
approach is to simply not include libdir in the .pc file at all.
THis patch hence more or less reverts both commits again, and moves the
.pc file back into pkgconfigdatadir.
As alternative for querying the systems primary libdir there's now
"systemd-path system-library-arch", hence a more correct alternative
exists for querying this variable from the .pc file.
We shouldn't destroy IPC objects of system users on logout.

This introduces SYSTEM_UID_MAX defined to the maximum UID of system
users. This value is determined compile-time, either as configure switch
or from /etc/login.defs. (We don't read that file at runtime, since this
is really a choice for a system builder, not the end user.)
While we are at it we then also update journald to use SYSTEM_UID_MAX
when we decide whether to split out log data for a specific client.
We export the location of a bunch of directories this way,
so it makes sense to add those three. Especially catalogdir
is something that we want people to add things to.
Note on the naming: the first two are tied closely to systemd
itself, so I prefixed them with "systemd". The third one is
rather more generic, so no prefix.
