  Log:
  ABI breaker: Move the J_SIGMASK field in the jmpbuf before
  the J_SIG0 field. While here, rename J_SIG0 to J_SIGSET and
  remove J_SIG1. The main reason for this change is that the
  128-bit sigset_t is now aligned on a 16-byte boundary, which
  allows us to use 16-byte atomic loads and stores on CPUs that
  support it. The removal of J_SIG1 is done to avoid confusion:
  it is never accessed and should not be. Renaming J_SIG0 to
  J_SIGSET is the icing on the cake that's better done now than
  later.
