globalvar: Add support for printing all global variables
...
This could previously only be done with 'devinfo global'. While
this is still possible this adds a more direct access via the
globalvar command. This variant also adds a '*' in front of
the variable if the corresponding non volatile variable exists.

Add support for non volatile variables
...
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

param: let dev_add_param return the newly created param
...
dev_add_param creates a new parameter so it makes more sense to
return it than to return an error code. Since the return value
is hardly ever checked this is only a small patch.

treewide: Add missing includes
...
A lot of files rely on include/driver.h including include/of.h (and
this including include/errno.h. include the files explicitly so we can
eventually get rid of including of.h from driver.h

globalvar: Do not modify already existing variables
...
When globalvar_add_simple was called on previously existing variables
then the value was overwritten, even when value was passed as NULL.
Do not overwrite the value in this case which allows us to do a 'global'
on the same variable multiple times without loosing the values.

Add a global.version variable
...
So far we only had the version command which is able to print
the barebox version. To make the barebox version available for
scripts add a globalvar for it.

Calling globalvar_add_simple() and setting a value is more than common.
Add a parameter for the initial value.

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.
