Cyrus extension fixes

Hello, I made a huge patch for the cyrus imap extension to get it usable with the recent versions of cyrus-imapd. The patch against the HEAD of pecl/cyrus module can be downloaded from the following place: http://www.voltex.jp/patches/cyrus-misc-fixes-20040620.patch.diff.txt The attached text file briefly describes how it can be used in reality. The changes include: - Changed cyrus_query() to correctly issue imclient_processoneevent() calls until the end of the response sequence. - Changed cyrus_query() to return the status of the query instead of a simple boolean value. - Fixed cyrus_bind() to keep the php_cyrus_callback instance in the linked list associated to the resource descriptor, instead of passing one allocated in the stack frame to imclient_addcallback() as a "rock", to prevent following undesired crashes in the callback function. - Fixed memory leaks in cyrus_generic_callback(), by changing it to destroy the return value resulted from the user land callback on success. - Modified cyrus_authenticate() so it can handle password authentication without a console interaction by adding SASL callbacks. - Added two #include's to prevent warnings. - Some typo / CS fixes. Although it was one of the things I was really careing about, I'm not sure if this completely maintains backwards compatibilities. If there's no problem, please commit this one. Hope this will save someone's time. Thanks, Moriyoshi
