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

Increase the default system log buffer size
from 16 kB (built-in default in ubox logd)
to 64 kB by setting the option in /etc/config/system.

Now that config_generate is able to generate the entire /etc/config/system
from scratch we can apply the same logic as used for /etc/config/network;
when the configuration file exists already then do not do anything, else
generate it from the values provided by /etc/board.json .
In order to facilitate that move the file existance checking inside
/bin/config_generate and call it unconditionally from /bin/board_detect.

The json_select call fails when there are no roles or ports objects in board.json. "json_select .." must not be executed after failing.
This fixes for example LEDs not being set up in /etc/config/system.

Instead of having two different types adsl and vdsl just create one dsl
type. This way we can use the same luci code for adsl and vdsl and the
config parameters are not so different.

This patch adds extra parameter to switch LED trigger initialization
functions. New functionality maintains backward compatibility, so
calling functions without setting new speed_mask parameter works
as expected.

This adds support for specifying the dsl modem, atm bridge configs and setting
the pppoe protocol for wan.
These additions are required to port the Lantiq target to board.d.

Some boards, e.g. the Sheeva Plug, require the lan interface to be set

Remove support for now unused ucidef_add_switch_vlan(), move port->vlan and
vlan->interfaces conversion to uci-defaults-new.sh and massively simplify
config_generate.
This change prepares the following upcoming steps:
* Eliminate use of ucidef_set_interface_lan_wan() for switch only devices
* Merge ucidef_add_switch() with ucidef_add_switch_ports()

Calculate complements by using awk's xor() function with a mask of 0xffffffff

the attached patch makes ipcalc.sh accept IP/Netmask combinations in
CIDR notation. Before you could only do:
# sh ipcalc.sh 192.168.0.0 255.255.255.0 1 10
IP=192.168.0.0
NETMASK=255.255.255.0
BROADCAST=192.168.0.255
NETWORK=192.168.0.0
PREFIX=24
START=192.168.0.1
END=192.168.0.11
with this patch you can also execute it with:
sh ipcalc.sh 192.168.0.0/24 1 10
IP=192.168.0.0
NETMASK=255.255.255.0
BROADCAST=192.168.0.255
NETWORK=192.168.0.0
PREFIX=24
START=192.168.0.1
END=192.168.0.11
The patch is based on #1260 [1], i just changed one line to calculate
the START end END ips right. I wonder why that never got included. If
there is no reason not to do i would like to ask you to commit that
patch, because its a functionality i (and probably others) miss quite often.
Btw, i also fixed 4 useless tabs, that might look a bit strange in the
patch.
