lib-imap-urlauth: Fix segfault occurring when userid part is missing for "user+" or "submit+" URLAUTH access.

Updated copyright notices to include the year 2018.

imap-urlauth: Allow connections from services other than IMAP. The imap-urlauth service detects the new submission service and assigns the appropriate privileges. The dovecot-token authentication mechanism provides information on which service connected to it.

Updated copyright notices to include the year 2017.

lib-imap: Started using struct uri_host in struct imap_url.

uri-util: Removed have_port and have_host_ip flags. Presence of port can be tested with port != 0. Presence of IP can be tested with ip->family != 0.

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

lib-imap-urlauth: Minor fix to avoiding timing attacks against mailbox existence. random_fill() is slightly slower than random_fill_weak(). Probably even better way to handle timing attacks would be to always add a short random pause before returning verification failure.

Moved random_init() from lib-imap-urlauth to imap/imap-urlauth main(). This way if the processes are chrooted they are still able to open /dev/urandom.

imap-urlauth: Store urlauth keys to the new mailbox attributes.

imap-urlauth: Use mailbox GUID instead of mailbox name for dict keys

imap urlauth: Don't autofill imap_urlauth_host. Use "*" value to mean "any host".

lib: Generalize hmac to be hash independent

imap-urlauth: Fixes to handling anonymous user

Added support for IMAP URLAUTH and URLAUTH=BINARY extensions Extends imap service with URLAUTH and URLAUTH=BINARY support: - Adds new commands URLFETCH, GENURLAUTH and RESETKEY. Creates imap-urlauth service in src/imap-urlauth. Functionality common to both the imap and imap-urlauth services is located in src/lib-imap-urlauth. TODO: - use mailbox GUIDs instead of names - doveadm command to delete stale urlauth entries? - add delay when attempting to access nonexistent user - create urlauth-worker queue, similar to how indexer-worker works (could we share code?..)
