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.

hush getopt: shift argv arguments ...

Make the nonopt arguments to a script available starting from $1
after running getopt. This allows for scripts which use option
parsing but also have nonopts.

resource: store 'end' instead of 'size' in struct resource ...

Storing the size instead of the resource end in struct resource was
a mistake. 'size' ranges from 0 to UINT[32|64]_MAX + 1 which obviously
leads to problems. 'end' on the other hand will never exceed
UINT[32|64]_MAX. Also this way we can express a iomem region covering
the whole address space.
