V2 changes:
 - Keep using /var/lib for the lease file, but making it respect localstatedir
 - Don't pass an empty --conf-file as that confuses dnsmasq when
   /etc/dnsmasq.conf doesn't exist or isn't readable.

Update centos.common.conf.in

systemd services like logind and journald need CAP_SETFCAP CAP_SETPCAP

use `hostname` for DHCP_HOSTNAME in ifcfg-eth0

Updated centos/fedora/oracle templates to use `hostname` for DHCP_HOSTNAME in
/etc/sysconfig/network/ifcfg-eth0, so the container's host name is propagated
to the host's DHCP server (e.g. dnsmasq, which also acts as the DNS server).
This resolves lxc/lxd#756

Adopt capability (lxc.cap.drop) documentation from other distros in Gentoo config, drop setpcap and sys_nice

Documents setpcap,sys_admin,sys_resources as breaking systemd, but does not drop them from lxc.cap.drop, as the default init system on Gentoo is OpenRC, thus stuff breaking systemd can be blocked anyway.

This also drops setpcap and sys_nice caps, as these are also dropped in other non-systemd distros.

Most of the explanatory blurb was copied from other distros' configs.

When starting a daemonized container, only the original parent
thread should return to the caller.  The first forked child
immediately exits after forking, but the grandparent child
was in some places returning on error - causing a second instance
of the calling function.

Update lxc-oracle.in fix a bug

In various places throughout the code, we want to "nullify" the std fds,
opening them to /dev/null or zero or so. Instead, let's unify this code and do
it in such a way that Coverity (probably) won't complain.

v2: use /dev/null for stdin as well
v3: add a comment about use of C's short circuiting
v4: axe comment, check errors on dup2, s/quiet/need_null_stdfds
