    Implement a wrapper for wcslen on Linux, assuming that
    sizeof(wchar_t) == 4, which I believe to be true on both Linux
    and MacOSX.  Fixes #298281.

Title:
  wcslen reads beyond the end of the buffer

Status in Valgrind:
  Unknown
Status in valgrind package in Ubuntu:
  Triaged

Bug description:
  valgrind reports many errors of wcslen reading beyond the end of the
  buffer.  It appears that sysdeps/x86_64/wcslen.S tries do do 64 bit
  reads which can result in reading beyond the end of the buffer if
  there are less than 64 bits left.
