imap-hibernate: Avoid using casts

imap-hibernate: Support userdb in var_expand

Updated copyright notices to include the year 2017.

lib: API change - var_expand*() now returns error string. This allows callers to fail properly if the format string is invalid.

imap-hibernate: Fix "DONE" handling. 1. If only "DONE\r\n" was sent, it randomly failed with BAD because of out-of-bounds buffer read. 2. If "DONE\r\n" was followed by a command tag but no space afterwards, we kept waiting for the input to continue. But since the DONE was already sent, we should break the IDLE already at that point without any further waiting.

global: Try to initialize var_expand_tab[] directly. This avoids accidents with the array numbering being wrong.

global: Use i_strchr_to_next() wherever useful.

%{auth_domain} shouldn't include the leading '@'

imap-hibernate: Preserve mail_user.session_create_time through hibernation

imap-hibernate: Properly fix hibernation The previous fix did not properly fix hibernation as the clients still dropped out of hibernate. Also the tag used was no longer following. This change will track tag changes and keeps the hibernation process going on until the user enters something else than DONE\r\ntag IDLE\r\n in same packet.

imap-hibernate: Accept RFC DONE\IDLE Change imap-hibernate to accept DONE\r\n<tag> IDLE\r\n as well, which is specified by RFC

imap-hibernate: fix input_pending check in client_unhibernate_cmp Check c2->input_pending instead of c1->input_pending when calculating comparison value for c2.

imap-hibernate: If imap-master socket is busy, retry un-hibernation later.

lib: remove autoclose parameter from [io]_stream_create_fd Use [io]_stream_create_fd_autoclose() for autoclose.

Remove t_malloc in favour of t_malloc_no0 Using either t_malloc_no0 or t_malloc0 makes it clear whether the allocated memory is zeroed or not.

global: Replaced all i_stream_read_data() with _more() and _bytes()

imap-hibernate: send connect/disconnect events to anvil make doveadm who + mail_max_userip_connections work with hibernated connections.

global: freshen copyright git ls-files | xargs perl -p -i -e 's/(\d+)-201[0-5]/$1-2016/g;s/ (201[0-5]) Dovecot/ $1-2016 Dovecot/'

Fixed compiler warnings in some systems. major() and minor() are unsigned ints nowadays, but in Solaris it's major_t. Cast them explicitly to avoid compiler warnings, and use unsigned longs instead of unsigned ints just in case.

imap-hibernate: Use sockets' st_dev and st_ino to verify that the passed fd is correct.

Added imap-hibernate process for gathering IDLEing imap processes. imap_hibernate_timeout setting controls how quickly the connection is moved from imap process to imap-hibernate process. Some IMAP extensions like NOTIFY, SEARCH=CONTEXT and COMPRESS aren't supported yet. There's also a new X-STATE command, which can be used to export the current IMAP connection state to a string and later on imported to get back to the original state (a quick resync feature for IMAP clients). However, this command is disabled for now due to the current code being unoptimized for untrusted input.
