Remove now-unnecessary direct stdlib.h #includes.

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.

imap-zlib: Removed check for disallowing COMPRESS to be used with TLS compression. Clients shouldn't be doing this in any case, and this check doesn't work properly with proxies. We could solve the check properly for Dovecot proxies by having them send the TLS compression state to backends, but it would still leave non-Dovecot proxies broken. Although we could just not advertise COMPRESS=DEFLATE extension if TLS compression is enabled and non-Dovecot proxies at least wouldn't cause failures. Still, overall seems like a lot of work for such a small and probably unnecessary extra check.

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

Plugin ABI version checking improvements. Previously the plugin version was checked against the version string returned by the currently running Dovecot master process, not necessarily the same as the binary. Also version_ignore=yes setting skipped the version check entirely. Now there's a new DOVECOT_ABI_VERSION macro that can (at least in theory) be updated only when the ABI actually changes. The version is in format "2.2.ABIv1(2.2.15)", where the (2.2.15) would be the actual Dovecot version number that gets ignored when comparing the strings. Also now the plugin version is compared to the actually running binary's ABI, not the master's version, and it can't be ignored with a setting.

Moved zlib/bzlib code to lib-compression library.

Avoid using (void)s by adding ATTR_NOWARN_UNUSED_RESULT attributes and other ways.

Make sure we check all the functions' return values. Minor API changes to simplify this. Checked using a patched clang that adds attribute(warn_unused_result) to all functions. This commit fixes several error handling mistakes.
