envfs: add support of variable inode size ...

Introduce a struct envfs_inode_end with more data.
Today this will just containt the file mode to be able to add the symlink
support.

But this is compatible with the previous envfs version as they will do not
care about the extra as the previous version is just reading the filename and
then consume the extra data without using them.

Increase the envfs version to 1.0

hush: catch errors from execute_binfmt ...

execute_binfmt may return negative return values which hush interprets
as 'exit'. Catch this and print an error message instead.

hush: Make exit a shell builtin ...

'exit' used to do its job by returning value < 0. This is a sign
for hush that 'exit' is executed. This has problems:

- Often commands accidently return a negative value. This causes
  the shell to exit.
- execute_binfmt returns a negative value when it does not find
  a binary to execute. This again causes the shell to exit.
  Returning a negative error value seems to be the right thing
  to do, but catching this in the shell would mean that the exit
  command does not work anymore.
- if called without arguments exit is supposed to return the code
  of the last command. As a command exit has no access to this code.

This patch changes exit to be a builtin and also fixes the last return
code problem. While at it, update the help text.

compressed image: add gzip support ...

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.
