dhcp: switch to global var support ...

This way you can specify as previously set the dhcp parameter via global.dhcp.xxx
and get the result via global.dhcp.xxx

This is need for the defaultenv-2 to add the bootp suppport.
Use it on defaultenv too to have only one set of var.

defaultenv: don't overwrite $user in config ...

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

but in hush it seems to do the right thing.

net: dhcp: allow to set transmitted vendor id ...

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.
