rc.d: Introduce 'dhcp_client' to wrap over dhclient and dhcpcd

The new 'dhcp_client' rc script is a wrapper to start either dhclient(8)
or dhcpcd(8) based on the value of the 'dhcp_client' rc variable.

Other rc scripts are updated to depend on this wrapper instead of the
explicit 'dhclient'. This eases the migration from dhclient(8) to
dhcpcd(8) later.

Update rc.conf.5 and dhcp.8 man pages accordingly.

Meanwhile, remove the two obsolete variables 'dhcp_{program,flags}' from
/etc/rc.subr.
