defaultenv-2: add bnet script to second stage barebox over net ...

Doing cycling barebox boot over the net is a good testing practice.
It is possible to detect at least some bugs before flushing it to
the system. Suddenly it looks like, it is done not oft enough. So, let's
add this option mainline.

build: fix that defaultenv is always rebuilt ...

From fcffd01 Mon Sep 17 00:00:00 2001
From: Sam Ravnborg <sam@ravnborg.org>

Subject: [PATCH 1/4] build: fix that defaultenv is always rebuilt

Using following pattern:

	target: prerequisite FORCE
		$(call cmd,foo)

is almost always wrong. Due to FORCE target will be rebuilt
using cmd_foo no mater the timestamps.

The following pattern:

	target: prerequisite FORCE
        	$(call if_changed,foo)

Will call cmd_foo only if:
- target is not updated
- or command to built target has changed

But to make this work target must be added to the
list af targets built.
This can be done by assigning target to extra-y or targets.

Use the latter pattern for defaultenv to avoid rebuilding
the environmentt for each build.

defaultenv-2: set bootargs correctly for network boot ...

The defaultenv-2 network boot script uses bootargs-ip which
hardcodes eth0 as network device. To make this work with
other nwetork devices use the "ip_route_get" command to determine
the network device used to reach the server.

net: environment: update automounts ...

Instead of using "ifup ethx" use "ifup -a" which works with all
network interfaces. Also replace "$ethx.serverip" with
"$global.net.server". This makes the automount independent of
the actual network interface. Remove all board specific
/env/init/automount files which were only there to use eth1 instead
of the previously hardcoded eth0.

login: rework login mechanism ...

We used to have the login functionality in the /env/bin/init script.
This is hard to review and it's too easy to break the login functionality
with changes to this script. Move the places to ask for a password to
C code where we have only a few places where we have to ask for a password.
Mainly these are run_shell() and the menutree command.

This patch introduces a login() function which will only return if the correct
password has been entered. Following calls will return immediately without
asking for a password again.

defaultenv-2: Make use of nonvolatile variables ...

This moves the variable assignments previously done in /env/config-board
to non volatile variables in /env/nv/. This makes the settings adjustable
by the user without editing a file.

Most of the changes are simple conversions which for many boards makes
/env/config-board unnecessary. Some boards had some logic to assign
global.boot.default based on the current bootsource. This has been
moved to /env/init/bootsource. An additional check is added to not
overwrite a nv.boot.default should it exist.

in the board file and not the other way around. Made sure that
