dsync: Add hashed_headers setting This makes it possible to configure them

Updated copyright notices to include the year 2017.

global: Replaced all instances of memset(p, 0, sizeof(*p)) with the new i_zero() macro. Used the following script: C_FILES=`git ls-files *.c` H_FILES=`git ls-files *.h` for F in "$C_FILES $H_FILES"; do echo "$F" perl -p -i -e 's/safe_memset\(&\(?([^,]*)\)?,\s*0,\s*sizeof\(\g1\)\)/i_zero_safe(&$1)/g' $F perl -p -i -e 's/safe_memset\(([^,]*),\s*0,\s*sizeof\(\*\g1\)\)/i_zero_safe($1)/g' $F perl -p -i -e 's/memset\(&\(?([^,]*)\)?,\s*0,\s*sizeof\(\g1\)\)/i_zero(&$1)/g' $F perl -p -i -e 's/memset\(([^,]*),\s*0,\s*sizeof\(\*\g1\)\)/i_zero($1)/g' $F done

global: Make sure i_stream_read() calls handle 0 and -2 return values correctly.

lib-mail: message_header_hash_more() now allows input in any slices. There wasn't necessarily any guarantees that the input would be sliced in such a way that the repeating '?' would be dropped the same way every time.

doveadm sync/backup: Added -S <max size> parameter to skip too large mails.

lib: istream - migrate to i_stream_read_more() Scripted to find all the low-hanging-fruit (single line calls), but hand-checked: git grep i_stream_read_data.*,\ 0\) | sed s/:.*// | \ xargs sed -i -e 's/i_stream_read_data(\(.*\), \(.*\), \(.*\), 0)/i_stream_read_more(\1, \2, \3)/' Signed-off-by: Phil Carmody <phil@dovecot.fi>

lib-mail: Changed message_header_hash_more() to support any hash algorithm

lib-mail, dsync: Moved dsync_mail_hash_more() to lib-mail/message-header-hash.*

dsync: Improved header hash v2 algorithm to remove repeated '?' chars. This is to help with Yahoo that replaces UTF-8 chars in headers with a single '?' (instead of '?' per each 8bit byte).

dsync: When comparing headers' hashes to match messages, try to normalize the input. This is especially useful because some IMAP servers return different data depending on whether we're fetching only specific header fields, all headers or entire body. For now we're assuming that any non-ASCII is going to be replaced with '?', which helps at least with Zimbra and Yahoo. The header hashing algorithm is now versionable, so it can be modified more easily in future. This change should make imapc_features=zimbra-workarounds setting obsolete.

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/'

dsync: Added -t <timestamp> parameter to save only mails newer than <timestamp> If one side has old mails that don't exist on the other side, they are ignored (not synced and not deleted).

global: freshen copyright Robomatically: git ls-files | xargs perl -p -i -e 's/(\d+)-201[0-4]/$1-2015/g;s/ (201[0-4]) Dovecot/ $1-2015 Dovecot/' Happy 2015 everyone! Signed-off-by: Phil Carmody <phil@dovecot.fi>

dsync: Added DSYNC_BRAIN_FLAG_NO_MAIL_PREFETCH to avoid opening mails unnecessarily.

dsync: saved-date doesn't need to be looked up until mail body is being read. This should improve the performance when the saved-date isn't already cached or otherwise quickly accessible. This change also makes dsync slightly incompatible with earlier versions. When using dsync with an earlier version the saved-dates aren't synced. It would be too much trouble to try to preserve full backwards compatibility, especially because saved-date doesn't matter so much and isn't even visible to IMAP clients.

Updated copyright notices to include year 2014.

dsync: Give hints to lib-storage about what fields we're going to fetch.

dsync: Various importer fixes. Handle unexpectedly wrong mailbox state better.

dsync: When doing a header-based sync, convert all linefeeds to LFs. Fixes syncing where one side used CRLFs and the other side used LFs.

dsync: When looking up header hashes, use only Date: and Message-Id: headers This makes it more efficient, at least in future when imapc backend optimizes this.

Oops :) Update copyrights to 2013 without breaking all .c files.
