This fixes several mbox problems previous v1.1 releases have had.

* mail_max_userip_connections limit no longer applies to master user logins.

+ login_log_format_elements: Added %k to show SSL protocol/cipher information.
  Not included by default.
+ imap/pop3-proxy: If auth_verbose=yes, log proxy login failures.
+ deliver: Added -s parameter to autosubscribe to autocreated mailboxes.
- message parser fixes - hopefully fixes an infinite looping problem
- SORT: One more assert-crashfix when renumbering index sort IDs.
- mbox: Saving may have truncated the mail being saved
- mbox: Several other bugfixes
- mail_full_filesystem_access=yes was broken when listing mailboxes (it still
  is with maildir++ layout).
- maildirlock utility was somewhat broken
- zlib plugin: bzip2 support was somewhat broken
- NFS: Make sure writing to files via output streams don't assert-crash when
  write() returns only partial success.
