lists: add list sorting routine

We need a list sorting function, just to mention one example user that could
benefit is the lib/tt code to sort columns.

This patch adds list_sort() which uses the Merge Sort algorithm, behaving
nicely in O(nlog(n)), heavily based on the kernel's implementation[1].  The
private data (void *priv) passed to the comparison function as been removed to
adopt a qsort(3)-like syntax, and IMHO we don't really need it anyways.

agetty: don't use log_err() for non-fatal errors

The TIOCSCTTY ioctl requires that caller is session leader -- so it
depends on initd (or we have to add setsid() to aggety). It seems that the
traditional way is to setup tty in agetty and session in login(1).

It means that all session related things (TIOCSCTTY, vhangup, ...) in the
command agetty should be optional. (Note that vhangup() is called when
--hangup is explicitly specified on command line, so log_err() makes
sense there.)
