Function db_lookup_proc

* Lookup a process based on a db expression address. We assume that the * address was parsed in hexadecimal. We reparse the address in decimal * first and try to treat it as a PID to find an associated process. * If that fails we treat the addr as a pointer to a process. */

 * If that fails we treat the addr as a pointer to a process.
