Find the AS for given A\+SP + optional routing context IE. 

if rctx\+\_\+ie == N\+U\+LL, we assume that this A\+SP is only part of a single AS; if rctx\+\_\+ie is given, then we look-\/up the A\+SP based on the routing context, and verify that this A\+SP is part of it. 
\begin{DoxyParams}[1]{Parameters}
\mbox{\tt out}  & {\em as} & caller-\/provided address-\/of-\/pointer to store the found AS \\
\hline
\mbox{\tt in}  & {\em asp} & A\+SP for which we want to look-\/up the AS \\
\hline
\mbox{\tt in}  & {\em rctx\+\_\+ie} & routing context IE (may be N\+U\+LL) to use for look-\/up \\
\hline

\begin{DoxyReturn}{Returns}
0 in case of success; \{M3\+UA,S\+UA\}\+\_\+\+E\+R\+R\+\_\+$\ast$ code in case of error.
