This patch fixes a couple of NPTL issues and continue to refactor the
cancellation code to simplify the required synchronization.

Adhemerval Zanella (6):
  nptl: Fix tst-cancel7 and tst-cancelx7 race condition (BZ #14232)
  nptl: Set cancellation type and state on pthread_exit
  nptl: Handle robust PI mutexes for !__ASSUME_SET_ROBUST_LIST
  nptl: Do not use pthread set_tid_address as state synchronization (BZ
    #19951)
  nptl: Move setxid flag out of cancelhandling
  nptl: Replace struct thread cancelhandling field
