new config directives: $IMUXSockLocalIPIF

The new default turns off rate limiting. This was chosen as people
experienced problems with rate-limiting activated by default. Now it
needs an explicit opt-in by setting this parameter.
Thanks to Chris Gaffney for suggesting to make it opt-in; thanks to
many unnamed others who already had complained at the time Chris made
the suggestion ;-)

which contains some properties obtained from the system and as such
sure to not be faked. This is inspired by the similiar idea introduced
in systemd.

This permits to read the time a message was submitted to the system
log socket. Most importantly, this is provided in microsecond resolution.
So we are able to obtain high precision timestampis even for messages
that were - as is usual - not formatted with them. This also simplifies
things in regard to local time calculation in chroot environments.
Many thanks to Lennart Poettering for suggesting this feature,
providing some guidance on implementing it and coordinating getting the
necessary support into the Linux kernel.

by doing math a little bit more optimal in hash table code. Also reduced
memory requirement for imuxsock hash tables (expected number of connections
was set too high -- table can be extended dynamically).
