  Log:
  Fix a bug in dlinfo(RTLD_DI_SERINFOSIZE) requests.  For each search path
  we included the length of the path in the returned size but not the length
  of the associated Dl_serpath structure.  Without this fix, programs
  attempting to allocate a structure to hold the search path information
  would allocate too small of a buffer and rtld would overrun the buffer
  while filling it via a subsequent RTLD_DI_SERINFO request.
