[Dovecot] v1.1.19 released

http://dovecot.org/releases/1.1/dovecot-1.1.19.tar.gz http://dovecot.org/releases/1.1/dovecot-1.1.19.tar.gz.sig

This is hopefully the last v1.1.x release.

- file_set_size() was broken with OSes that didn't support
  posix_fallocate() (almost everyone except Linux), causing all kinds
  of index file errors.
- ldap: Fixed hang when >128 requests were sent at once.
- Fixed a crash in saving messages where message contained a CR
  character that wasn't followed by LF (and the CR happened to be the
  last character in an internal buffer).
- deliver: Don't send rejects to any messages that have Auto-Submitted
  header. This avoids emails loops.
- Message decoding fixes (mainly for IMAP SEARCH, Sieve).
