v2.2.36 release candidate released

https://dovecot.org/releases/2.2/rc/dovecot-2.2.36.rc1.tar.gz https://dovecot.org/releases/2.2/rc/dovecot-2.2.36.rc1.tar.gz.sig

v2.2.36 is hopefully going to be the last v2.2.x release. Please test this RC well, so we'll have a good final release! v2.3.2 is still going to take a couple of months before it's ready.

• login-proxy: If ssl_require_crl=no, allow revoked certificates. Also don't do CRL checks for incoming client certificates.
• stats plugin: Don't temporarily enable PR_SET_DUMPABLE while opening /proc/self/io. This may still cause security problems if the process is ptrace()d at the same time. Instead, open it while still running as root.

• doveadm: Added mailbox cache decision&remove commands. See doveadm-mailbox(1) man page for details.
• doveadm: Added rebuild attachments command for rebuilding $HasAttachment or $HasNoAttachment flags for matching mails. See doveadm-rebuild(1) man page for details.

• dsync: Lock file generation failed if home directory didn't exist
• Snippet generation for HTML mails didn't ignore &entities inside blockquotes, producing strange looking snippets.
• imapc: Fix assert-crash if getting disconnected and after reconnection all mails in the selected mailbox are gone.
• pop3c: Handle unexpected server disconnections without assert-crash
• fts: If mails contained NUL characters, the text around it wasn't indexed.
• Obsolete dovecot.index.cache offsets were sometimes used. Trying to fetch a field that was just added to cache file may not have always found it.
