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>.
   -  Accept a passwordless account ("" or "!").
      See <#1483 (comment)>
      and <#1505>.

Closes: <#1487>
