network: Update rtsol options

- Use "-6" instead of "--noipv4" as it seems more appropriate based on
the dhcpcd(8) manual page.
- Remove "-f /dev/null" as it seems unnecessary with "-6".
- Remove "--persistent" as it is in the default /etc/dhcpcd.conf,
and this way the user can change it, if they would like to (either
through dhcpcd_flags or by editing /etc/dhcpcd.conf).

The "-b" (or "--background") option is needed to avoid a timeout error
message (and a delay in booting), so it is still left in place.

Update "rtsol" keyword: leave IPv6 autoconf on

There is no need to turn off ipv6_autoconf or dhcp6 in dhcpcd to match
the previous behaviour with in-kernel RA processing.

Make "rtsol" functional again.

Rename MOUNTCRITLOCAL to CRITLOCALMOUNTED to avoid a name collision
on case insensitive file systems

Split the local disk availability step into two phases to allow scripts
that pre-populate parts of the system (e.g. a tmpfs based /var) an
easy place to plug in like:

# REQUIRE: mountcritlocal
# BEF

Split the local disk availability step into two phases to allow scripts
that pre-populate parts of the system (e.g. a tmpfs based /var) an
easy place to plug in like:

# REQUIRE: mountcritlocal
# BEFORE: MOUNTCRITLOCAL

This also cleans up the existing special handling a bit by separating it
into new scripts. All later scripts now depend on MOUNTCRITLOCAL.
Discussed on tech-userlevel some time ago.

Remove in-kernel handling of Router Advertisements

This is much better handled by a user-land tool.

Note that the ioctl SIOCGIFINFO_IN6 no longer sets flags. That now
needs to be done using the pre-existing SIOCSIFINFO_FLAGS ioctl.

Compat is fully provided where it makes sense, but trying to turn on
RA handling will obviously throw an error as it no longer exists.

Note that if you use IPv6 temporary addresses, this now needs to be
turned on in dhcpcd.conf(5) rather than in sysctl.conf(5).

Allow rc.conf to setup resolv.conf via resolvconf(8).
This allows all static network config to be in rc.conf rather than
spread across files.

Remove dhclient from the base system.

Instead of waiting for a duration based in IPv6 DAD count sysctl,
wait for 15 seconds for tentative flags to clear allowing 5 seconds
for detached flags to clear as well from configured addresses.

This is now protocol independant and allows time for the interfaces to
work out if they have a carrier or not.
