This wasn't Marian's doing. The ARTOS support was added back in 2003
(commit 7f70e853):
* Patch by Pantelis Antoniou, 21 Apr 2003:
add boot support for ARTOS (a proprietary OS)
How does one access the environment? The only API we seem to have
getenv, getenv_r, setenv and envmatch(). I'd argue that envmatch
should be removed from common.h as it exposes the internals of how the
env it stored.
There aren't any APIs to walk over all environment variables or to get
a list of all of them.
