ARM: remove ARCH_HAS_LOWLEVEL_INIT ...

This is unused now and not needed. We have a board_init_lowlevel. If a
board needs some architecture setup it can always call it from its
board_init_lowlevel.

Add compressed image support ...

This allows for creating a lzo compressed binary unsing the pbl.

Only copy the piggydata if needed.

Add CONFIG_PBL_FORCE_PIGGYDATA_COPY option
In some case we need to copy the PIGGYDATA as the link address
as example we run from SRAM and shutdown the SDRAM/DDR for
reconfiguration but most of the time we just need to copy the
executable code.

Add pre-bootloader (pbl) image support ...

This allows for creating a pre-bootloader binary for
 - nand boot
 - mmc boot
 - compressed image

The pbl will be incharge of the lowlevel init if needed.
The barebox will skip it.

Import string functions from linux 3.4 (arch/arm/boot/compressed/string.c) and
implement a dummy panic.

For now on introduce dummy zbarebox* targets and c code that will contain later
the decompressor. This only implemeted on ARM.

Enable a way to provide the reason for "being here" ...

Many architectures support a way to detect why the bootloader is running.
This patch adds a global variable to be able to use the cause in some kind of
shell code to do special things on demand. For example to do an emergency boot,
when the last boot fails and the watchdog reactivate the hanging system.

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.

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.

glob: Add sorted output support ...

add 'global' command ...

This implements global shell variable support. This is done by registering
a new device named 'global', so global variables are just plain device
parameters.
Global variables are useful for storing the global state in the environment.
Currently we do this by sourcing scripts instead of executing them which is
quite limiting.

Introduce binfmt support ...

This will allow to execute any file and detect it's type to handle it.
This will allow to use shell for bootp bootfile or dfu.

You can register multiple hook for the same filetype. They will be execute
in the invert order of register. If a hook does not handle the file you just
return -ERESTARTNOHAND;

This is only available with hush parser.
