patch 35/38: SERVER: new routine exp_pseudoroot() [trivial for now]

This patch defines exp_pseudoroot(), which is used to set the filehandle for the root of the pseudofs. Right now, we just use the root of an arbitrarily-selected export. This is just a placeholder until the pseudofs is properly implemented in 2.5.
