hush: do not convert to return code too early ...

parse_stream_outer used to convert a exit value to a return code,
but parse_stream_outer maybe inside a recursion. This means that
the exit status is lost in this case. Test case:

if [ 0 = 0 ]; then
	false
	exit $?
fi

echo "shouldn't be here"

Without this patch "shouldn't be here" will be printed.

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.

booting: more flexible Linux bootargs generation ...

We currently use the environment variable 'bootargs' to get the
Linux bootargs. This patch allows for a more flexible bootargs
generation using global variables. With it the Linux bootargs
are concatenated from multiple variables. This allows to replace
parts of the bootargs string without having to reconstruct it
completely.
With this bootargs can be constructed like:

global linux.bootargs.base="console=ttyS0,115200"
global linux.bootargs.ip="ip=dhcp"
global linux.mtdparts="physmap-flash.0:512K(nor0.barebox),-(root)"

This will then automatically be combined into a kernel bootargs
string during boot.

If the 'linux.bootargs.' variables are all empty the old standard
'bootargs' way will be used.

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.

uimage/file_to_sdram: fix resource allocation ...

file_to_sdram is used to load an initrd. The resource size is
then used to pass the initrd size to Linux. This means that
the resource size must exactly match the initrd size. Currently
this is not the case since we request the sdram region in chunks
of 8 Kbytes. Fix this by adjusting the resource size when the file
is loaded.
