  Added files:
    csup                 idcache.c idcache.h 
  Log:
  Add an implementation of a thread-safe cache for lookups in the group
  or password files, per name or per uid/gid.  It serves two purposes.
  First, it makes the code thread-safe by serializing calls to getpwuid()
  or getpwnam() and calls to getgrgid() or getgrnam().  Second, it's a
  cache so we avoid calling those functions several times for the same
  password/group file entry.  It's implemented using four separate hash
  tables (uid->name, gid->name, name->uid, name->gid).
