In apacheGetParamValues() and apacheGetFirstParamValue():

In apacheGetParamValues() and apacheGetFirstParamValue():
applied const qualifier to nkey.

Also: changed the ensuing NULL tests to look at nkey
instead of key, since key has already been verified as
non-NULL.

Actually it looks like nkey is guaranteed to be non-NULL
as well, but that depends on the correct functioning
of osrfStringArray; so I left the NULL test, as
revised, in place.
