Log Message:
Changes 4.73:
* Date: & Message-Id: revert to normally being appended to a message,
  only prepend for the Resent-* case.  Fixes regression introduced in
  Exim 4.70 by NM/22 for Bugzilla 607.
* Include check_rfc2047_length in configure.default because we're seeing
  increasing numbers of administrators be bitten by this.
* Added DISABLE_DKIM and comment to src/EDITME
* Bugzilla 994: added openssl_options main configuration option.
* Bugzilla 995: provide better SSL diagnostics on failed reads.
* Bugzilla 834: provide a permit_coredump option for pipe transports.
* Adjust NTLM authentication to handle SASL Initial Response.
* If TLS negotiated an anonymous cipher, we could end up with SSL but
  without a peer certificate, leading to a segfault because of an
  assumption that peers always have certificates.  Be a little more
paranoid.
* Bugzilla 926: switch ClamAV to use the new zINSTREAM API for content
  filtering; old API available if built with WITH_OLD_CLAMAV_STREAM=yes
  NB: ClamAV planning to remove STREAM in "middle of 2010".
  CL also introduces -bmalware, various -d+acl logging additions and
  more caution in buffer sizes.
* Implemented reverse_ip expansion operator.
* Bugzilla 937: provide a "debug" ACL control.
* Bugzilla 922: Documentation dusting, patch provided by John Horne.
* Bugzilla 973: Implement --version.
* Bugzilla 752: Refuse to build/run if Exim user is root/0.
* Build without WITH_CONTENT_SCAN. Path from Andreas Metzler.
* Bugzilla 816: support multiple condition rules on Routers.
* Add bool_lax{} expansion operator and use that for combining multiple
  condition rules, instead of bool{}.  Make both bool{} and bool_lax{}
  ignore trailing whitespace.
* prevent non-panic DKIM error from being sent to paniclog
* added tcp_wrappers_daemon_name to allow host entries other than
  "exim" to be used
* Fix malware regression for cmdline scanner introduced in PP/08.
  Notification from Dr Andrew Aitchison.
* Change ClamAV response parsing to be more robust and to handle ClamAV's
  ExtendedDetectionInfo response format.
* OpenSSL 1.0.0a compatibility const-ness change, should be backwards
  compatible.
