/*
  * Routines for controlled update/initialization of request structures.
  * 
  * request_init() initializes its argument. Pointers and string-valued members
  * are initialized to zero, to indicate that no lookup has been attempted.
  * 
  * request_set() adds information to an already initialized request structure.
  * 
  * Both functions take a variable-length name-value list.
  * 
  * Diagnostics are reported through syslog(3).
