linux.bootargs.dyn.* will be cleared at the beginning of boot
This is need for boot sequence to do not have the previous boot param.

- 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.

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.

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.

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).

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.
