Move preinit interface and ip config to its own function to allow
calling it from more than one place.

This commit:
1) seed /dev/urandom with the saved seeds as early as possible
(see /lib/preinit/81_urandom_seed)
2) save a seed at /etc/urandom.seed if it doesn't exists
3) save a new seed each boot at "system.@system[0].urandom_seed"
(see /etc/init.d/urandom_seed)
We use getrandom() so we are sure /dev/urandom pool is initialized
Seed size is 512 bytes (ie /proc/sys/kernel/random/poolsize / 8)
it's the same size as in ubuntu 14.04 and all systemd systems
Seeding /dev/urandom doesn't change entropy estimation, so we still have
"random: ubus urandom read with 4 bits of entropy available"
messages in the logs, but we can now ignore them if
after "urandom-seed: Seeding with ..." message
Saving a new seed on each boot is disabled by default to avoid too much
writes without user consent
v2: log preinit messages to /dev/kmsg
v3: use non generic function name for logging, as /lib/preinit/ files
are all sourced together in /etc/preinit
v4: after a lot of discussion on the ML, use a uci config param
v5: config param is now the path of the seed

This enables passworldless login for root via SSH whenever no root
password is set (e.g. after reset, flashing without keeping config
or in failsafe) and removes telnet support alltogether.

This new argument is used right after starting regular preinit (which
happens if failsafe wasn't triggered). The main purpose of "preinit"
argument is to indicate that failsafe can be triggered, however we were
missing a way to inform user that we don't wait for a trigger anymore.
With this change it's clear when failsafe mode can be triggered.

The behaviour of calling 'mount' differed depending on whether it called
the busybox-mount, the mount of util-linux, the mount defined in
/lib/functions.sh and /lib/functions/boot.sh
/etc/preinit even included /lib/functions.sh and /lib/functions/boot.sh,
both re-defining 'mount'.

Busybox built against musl-libc will choke on these otherwise, besides that
it is more natural to use the filesystem type, then options, then name, then
mountpoint.
