defenv-2 menu: when booting failed wait for key press ...

When booting fails we will be immediately be back into the menu,
so the error message can't be seen. Also, boot in verbose mode
since in interactive mode the last bit of performance is not that
necessary.

defenv-2: bring back /env/config ...

The idea of having /env/init/* scripts was to make the configuration
more flexible and customizable for boards. It turned out though that
people (including myself) do not find the place where they should
change these settings.

So this patch brings back /env/config for defenv-2. The individual
env/init/* scripts are removed and their content is added to
/env/init/config-board. This makes the values from /env/init/config-board
the board specific defaults which can be overwritten in /env/config.

defenv-2: remove some helper scripts ...

The added complexity of bootargs-ip-* and bootargs-root-* makes
understanding defenv-2 more complicated. remove them and open
code the scripts instead in their users.

defenv-2: remove initrd boot script ...

This is mostly an example and does not have a real use, so remove
it to not have it in each and every environment.

defenv-2: set username to 'none' ...

The current 'sha' setting, though admittedly very convenient for me,
was never intended to be in mainline.

defenv-2: improve boot script ...

- add usage information
- add option parsing:
  -v verbose
  -v -v more verbose
  -l list b´possible boot sources
  -d dryrun

The dryrun option sets the global variables necessary for booting
but does not actually boot the system. This way it is possible to
make additional adjustments to the boot variables and then invoke
bootm manually.

defaultenv-2 ifup: create network up state file for dhcp ...

We store the 'up' status of a network device in /tmp/network/$interface.
Create this file for dhcp aswell to prevent doing dhcp requests each
time ifup is called.

defaultenv-2: remove global.tftp.path ...

This variable is set in /env/init/general and then used
in /env/boot/* which is a bit confusing. Also it does not
necessarily have to be a tftp path (could be nfs aswell).
Use a local variable in the scripts using it instead to make
the meaning a bit more clear.

defaultenv-2: mount tftp server specified in $eth0.serverip ...

This is always the tftp server specified in /env/network/eth0,
this could be either the one returned from a dhcp request or
a manually specified one, but in the end it's always the right
one.

defaultenv-2 ifup: Always overwrite eth0.serverip ...

if serverip is specified, also overwrite eth0.serverip in dhcp
case. This makes it possible to specify a different serverip
when the dhcp server returns the wrong ip (because the DHCP
might be a DSL router which does not provide tftp).

Add next generation default environment template ...

This adds a new environment template which aims to be more flexible
and configurable. Instead of having mainly two scripts (a config script
and a boot script) this template uses initscripts which control the
startup behaviour and configuration. Also we have boot scripts in
/env/boot which configure a single boot configuration. Additional
boot entries can be added by board specific entries or during runtime
by copying and editing a template entry.

Some more helpers handle for example network interfaces which can now
be brought up with 'ifup'. We use the automount feature to configure
mountpoints together with the commands to bring up the devices behind
these mountpoints.

Optionally menu support is available which hides many details behind
a nice looking interface.
