Improve the documentation of bus credentials by mentioning send-time metadata. This needs more love, we should really clarify metadata details here. However, this is still better than nothing, so it's fine.
Rename sd_rtnl to sd_netlink to prepare for further netlink-protocol support. Anything rtnl specific still uses the sd_rtnl prefix, but the generic parts (including the bus and message objects) are now called sd_netlink.
This makes journalctl quit on ferror() conditions on stdout. It fixes an
annoying bug if you pipe its output through 'less' and press 'q'. Without
this fix journalctl will continue reading all journal data until EOF which
can take quite some time. For instance on my machine:
david-nb ~ # time journalctl | wc -l
327240
real 1m13.039s
user 1m0.217s
sys 0m10.467s
However, expected behavior is journalctl to quit when its pager closed the
output pipe.

If the system does not have any active console, we should not try to
create an empty symlink. Instead, create no symlink at all.
Otherwise, on systems with CONFIG_VT=n and no serial console, we will
create a symlink with an empty template parameter.
