[RFC][PATCH] libtirpc,rpcbind: move socket from /var/run to /run

[Tom Gundersen <teg@jklm.no>]

/run is guaranteed to be available and writeable at any time, whereas
/var might be on a separate partition and hence not available during
early boot. By moving the socket from /var to /run we are able to use
rpcbind earlier, which would in particular make a difference in case
/var is on an nfs mount, something I am currently seeing bug reports
about.

This change should not make a difference to software that currently
works as intended, as /var/run should be a symlink or bindmounted
to /run, so anyone relying on the socket being in /var/run will
still find it there.

The /run directory is supported by all the major distributions
(at least Debian, Fedora, Suse, Ubuntu and Arch from what I can gather).
See http://wiki.debian.org/ReleaseGoals/RunDirectory and
http://thread.gmane.org/gmane.linux.redhat.fedora.devel/146976 for some
more details.
