Initialize environment using argv[]

Hi,

As discussed here on -hackers@ :

https://lists.freebsd.org/pipermail/freebsd-hackers/2015-August/048071.html

and for the record, here are two simple patches that allows the EFI loader to
set environment variables from arguments and locally override the root path
offered through BOOTP (through a new variable called
"dhcp.root-path.override").

This allows to chainload loader.efi and pass your root-path (and any other
variable) this way (e.g. with iPXE) :

#!ipxe
chain http://path.to/loader.efi dhcp.root-path.override=server_ip:/path/to/root
some_other_var=value

Those patches are quite basic and will probably need refactoring, but you get
the idea :p

Regards,
Ganael.
