[Dovecot] 1.0.beta9 released

Fixes a lot of bugs. The next release will be the first "release candidate" instead of a beta.

* PAM: Don't call pam_setcred() unless setcred=yes PAM passdb
  argument was given.
* Moved around settings in dovecot-example.conf to be in more logical
  groups.

+ Local delivery agent (deliver binary) works again.
+ LDAP: Added support for SASL binding. Patch by Geert Jansen
+ ssl_verify_client_cert: Check CRLs. If auth_verbose=yes, log
  invalid sent certificates. If verbose_ssl=yes, log even the valid
  certificates. When using the username from the certificate, use
  CommonName. Based on patch by HenkJan Wolthuis
+ PAM: Set PAM_TTY which is needed by some PAM plugins
+ dovecot --exec-mail ext <binary path> can now be used to start
  binaries which want dovecot.conf to be read, for example the
  convert-tool.

  normal \-escaping.

  dovecot-auth.
