IMAP capabilities and selected folder are IMAP session, not IMAP client property. Moving most operations into IMAP session structure removes the need to constantly check whether IMAP session exists and reduces number of invalid states, e.g. when a folder is selected but there is no connection. Capabilities are determined immediately after logging in, so there is no need for `capabilities_determined` flag anymore. Capabilities of the server are always known if there is a session. `should_reconnect` flag and `disconnect()` function are removed: we drop the session on error. Even though RFC 3501 says that a client SHOULD NOT close the connection without a LOGOUT, it is more reliable to always just drop the connection, especially after an error.
