Update for NetBSD 9.3 and 10.0

[Bruno Haible]

NetBSD 10.0 was released a couple of days ago.

The main changes in libc:
  - New header file <sys/random.h>.
  - New functions getrandom and getentropy.
  - New functions posix_spawn_file_actions_addchdir,
    posix_spawn_file_actions_addfchdir.
  - New functions eventfd, eventfd_read, eventfd_write, ppoll.
  - New functions timerfd_create, timerfd_gettime, timerfd_settime.
  - New <math.h> functions expm1l, log1pl, log2l, remainderl. All of them
    are buggy.
  - 1 of the several bugs that I reported got fixed.

This patch updates the documentation and *.m4 files.
