Well, the call to setusercontext() is all the app needs. Currently xdm
already makes that call, but not in NetBSD as HAS_SETUSERCONTEXT is not
defined / no "#define HasSetUserContext YES" in NetBSD.cf. I believe
that is already sufficient to take care of setlogin()/initgroups() etc.
It also takes care of path/setenv within xdm, but when xdm starts the
session, it resets the environment, binning path/setenv by replacing it
with userEnviron - that is why the setuserpath()/setuserenv() is in there.
So, in otherwords this is just "fixing" what is already there, rather than
starting something new e.g., let's invent a new module..
