This moves the variable assignments previously done in /env/config-board
to non volatile variables in /env/nv/. This makes the settings adjustable
by the user without editing a file.
Most of the changes are simple conversions which for many boards makes
/env/config-board unnecessary. Some boards had some logic to assign
global.boot.default based on the current bootsource. This has been
moved to /env/init/bootsource. An additional check is added to not
overwrite a nv.boot.default should it exist.

This adds (back) support for non volatile variables. Non volatile
variables are variables which are stored in the environment over
reboot. They are used in the same way as the global variables, but
with a 'nv' command and device. The variables are stored under
/env/nv/, one variable per file. Adding a nv variable automatically
adds a global variable with the same name. Changing a nv variable
also changes the same global variable, but not the other way round.
This allows for example to configure the username as:
nv user=sha; saveenv

It's often useful to get some information about a barebox image
before starting or flashing it. This patch introduces barebox
Image MetaData (IMD). When enabled a barebox image will contain
a list of tags containing the desired information. We have tags
for:
- the barebox release (2014.07.0-00160-g035de50-dirty)
- the build timestamp (#741 Mon Jul 28 15:08:54 CEST 2014)
- the board model the image is intended for
- the device tree toplevel compatible property
Also there is an additional generic key-value store which stores
parameters for which no dedicated tag exists. In this patch it
is used for the memory size an image supports.
Since there is no fixed offset in a barebox image which can be
used for storing the information, the metadata is stored somewhere
in the image and found by iterating over the image. This works
for most image types, but obviously not for SoC images which are
encoded or encrypted in some way.
There is a 'imd' tool compiled from the same sources for barebox,
for the compile host and for the target, so the metadata information
is available whereever needed.
For device tree boards the model and of_compatible tags are automatically
generated.
Example output of the imd tool for a Phytec phyFLEX image:
build: #889 Wed Jul 30 16:08:54 CEST 2014
release: 2014.07.0-00167-g6b2070d-dirty

This patch does probably too much, but it's hard (and very
cumbersome/time consuming) to break it out. What is does is this:
* each command has one short description, e.g. "list MUX configuration"
* made sure the short descriptions start lowercase
* each command has one usage. That string contains just the
options, e.g. "[-npn]". It's not part of the long help text.
* that is, it doesn't say "[OPTIONS]" anymore, every usable option
is listed by character in this (short) option string (the long
description is in the long help text, as before)
* help texts have been reworked, to make them
- sometimes smaller
- sometimes describe the options better
- more often present themselves in a nicer format
* all long help texts are now created with BUSYBOX_CMD_HELP_
macros, no more 'static const __maybe_unused char cmd_foobar_help[]'
* made sure the long help texts starts uppercase
* because cmdtp->name and cmdtp->opts together provide the new usage,
all "Usage: foobar" texts have been removed from the long help texts
* BUSYBOX_CMD_HELP_TEXT() provides the trailing newline by itself, this
is nicer in the source code
* BUSYBOX_CMD_HELP_OPT() provides the trailing newline by itself
* made sure no line gets longer than 77 characters
* delibertely renamed cmdtp->usage, so that we can get compile-time
errors (e.g. in out-of-tree modules that use register_command()
* the 'help' command can now always emit the usage, even without
compiled long help texts
* 'help -v' gives a list of commands with their short description, this
is similar like the old "help" command before my patchset

- the the instance from the 'serial' alias
- the baudrate from the actual baudrate.

input.__promptme is no valid indicator that run_shell should be left.
It should be left on executing the 'exit' builtin which is indicated
by a return code < 0 from parse_stream_outer(). Track this with an extra
variable and use it as a condition to return from an interactive shell.
This fixes the weird behaviour that hush exits (and the user finds itself
in the menu) when a syntax error occured.

Instead of only allowing complete devices we now also allow single
partitions to look for bootloader spec entries.
Normally the bootloader spec defines a way to find a partition containing /boot
on a device. On embedded systems it's often useful instead to have only a
single partition image which contains both the kernel and the root filesystems.
This partition image may be written to the device multiple times. With this
patch they can be booted with 'boot emmc0.<partno>'

This adds a tool for installing kernels according to the bootloader
spec. systemd already has a similar tool, but it is limited to installing
kernels on the currently running system. The barebox kernel-install
tool instead can also be used to install kernels on removable media on a
development host for cross development. It is compiled in two variants,
as 'kernel-install' for the host and as 'kernel-install-target' using
$CROSS_COMPILE.

The Bootloader Specification describes a way how kernels can
be installed on devices and how they can be started by the bootloader.
The bootloader spec is currently supported by (x86) gummiboot and
by systemd which provides a kernel-install script. With the bootloader
spec it's possible for the Operating system to install a new kernel
without knowing about the bootloader and for the bootloader it's possible
to discover and start Operating Systems on a media without being
configured.
For more details about the spec see:
http://www.freedesktop.org/wiki/Specifications/BootLoaderSpec/
This patch adds barebox support for the spec. It enhances the 'boot'
command so that not only boot script names can be given, but also
devices containing bootloader spec entries. With this it's possible
to call the 'boot' command like: 'boot sd emmc net'. It would then
first look for bootloader spec entries on the (removable) sd card,
then, is nothing is found, on the internal emmc and if still
unsuccessful would call the 'net' bootscript.
The bootloader Spec currently doesn't specify which entry should be
default if multiple entries are found on a single device. Therefore
barebox currently has two extensions of the spec. The $BOOT diretory
can contain a file named 'default'. If present, the content of the
file is treated as a filename under $BOOT/loader/entries/ which is
used as default. Similarly if a file named 'once' is present, the
entry is started once and the file is removed afterwards. This is
useful for testing if a newly installed kernel works before making
it the default.
As on ARM and other Architectures a devicetree has to be specified
for the kernel, the 'devicetree' property is used to specify a
devicetree. Like 'kernel' and 'initrd' this also contains a pth
relative to $BOOT.

This introduces some new environment variable helpers and updates
the existing ones. Newly introduced are:
getenv_bool: read a bool variable
getenv_ul: read an unsigned long variable
getenev_uint: read an unsigned int variable
getenv_nonempty: like normal getenv, but does return NULL instead of an
empty string
All new helpers take a pointer to the value. This value is only modified
when the variable exists. This allows the following programming scheme:
unsigned int myvalue = sanedefault;
getenv_uint("myvalue", &myvalue);
So without checking the return value myvalue contains the best possible
value.
getenv_ull is updated to this scheme.

In theory we can overwrite a builtin command with a script. However,
I don't know a single case where this has been done. Scripts are
often more unflexible than commands so it's unlikely that a script
can extend the functionality of a builtin command. Moreover, the
internal command is no longer accessible once it's overwritten by
a script.
Invert this logic so that a builtin command can overwrite an existing
script. This will help when the 'boot' script is converted to a
builting command. Then with old environments the builtin command will
be used instead of the script.

We used to use struct image_data as the central data structure for bootm and
also as the input data structure. This makes it unclear which of the fields
are actually input data. This patch creates a struct bootm_data which is
exclusively used for input data to make usage clearer.
Also it moves the dispatching of multifile uImage pathnames to the core bootm
code so that the core code gets more flexible and the command code simpler.
