The defaultenv_add_base() functions adds the enviroment coming from
CONFIG_DEFAULT_ENVIRONMENT_PATH. But this is not only for
traditional enviroments, but also for external enviroments in e.g. build
systems. The external enviroment should override the enviroment set
in the board file and not the other way around. Made sure that
external enviroment is always added last.

Since commit a162dfe503 the ifup command runs
this file as a script. Due to a hush misbehave it could happen it returns
an error code by accident.
For example if the last instructions in this file are:
if [ false ]; then
echo "friesel"
fi
the hush returns 1 after running this script instead of 0 and in this case
the ifup command fails.
I know, the correct fix would be to fix the hush, because it is a generic
issue...but how?

DFU is for device firmware upgrade, but for development purposes it's
sometmes useful to just start a kernel vie DFU. This adds a boot option
for doing this and also the corresponding counterpart on the host. With
this it's possible to boot a system with:
scripts/dfuboot.sh -k linuximage -d dtb -c "root=ubi0:root ubi.mtd=ubi rootfstype=ubifs ignore_loglevel"

We can compile barebox for multiple boards at once, but currently
they all share a single default environment. This patch adds a
defaultenv_append() which boards can call to customize the default
environment during runtime. Each board now generate default environment
snippets using bbenv-y and add them during runtime with defaultenv_append()

This patch prooved to be useful while working with a colleague on a single
machine. It allows to switch the user without editing /env/config by
just issuing:
export user=me
. Note, in bash this construct (i.e. an if without body) bails out with:
Syntax error: "fi" unexpected

For net boot setups it is useful to submit boot params like server or
bootfile over dhcp. To distinguish barebox from e.g. pxe machines,
a custom vendor id can be sent in dhcp discover/request messages.
E.g. the ISC dhcp server can be configured with
| if substring(option vendor-class-identifier,0,8) = "barebox:" {
| next-server 192.168.3.24;
| server-name "192.168.3.24";
| option tftp-server-name "192.168.3.24";
| option root-path = concat("/srv/sysroots/by-mac/",
| binary-to-ascii (16, 8, "-", substring (hardware, 1, 6)));
| }
to sent boot params which are valid for barebox hosts only.
