Release 4.19.1

Regression fixes:

-  chpasswd(8):
   -  Don't reject leading '!' in password hashes or a hash consisting
      of "*".  These were accidentally rejected in 4.19.0.
      See <#1483>
      and <#1486>.

Security bug fixes:

-  vipw(8):
   -  Avoid predictable names for temporary files.
      This allowed anyone to read the contents of /etc/shadow.
      See <#1485>.

Other changes:

   -  Set SIGCHLD before fork(2).  This prevents a possible race
      condition, although this is only for making the code more robust;
      we believe that the code was correct.
