Log Message:
Changes 2.0.54:
  *) mod_cache: Add CacheIgnoreHeaders directive.
  *) mod_ldap: Added the directive LDAPConnectionTimeout to configure
     the ldap socket connection timeout value.
  *) Correctly export all mod_dav public functions.
  *) Add a build script to create a solaris package.
  *) worker MPM: Fix a problem which could cause httpd processes to
     remain active after shutdown.
  *) Unix MPMs: Shut down the server more quickly when child processes are
     slow to exit.
  *) Remove formatting characters from ap_log_error() calls.  These
     were escaped as fallout from CAN-2003-0020.
  *) mod_ssl: If SSLUsername is used, set r->user earlier.
  *) htdigest: Fix permissions of created files.
  *) core_input_filter: Move buckets to a persistent brigade instead of
     creating a new brigade. This stop a memory leak when proxying a
     Streaming Media Server.
  *) mod_win32: Ignore both PATH_INFO as well as PATH_TRANSLATED to avoid
     hiccups from additional path information passed in non-utf-8 format.
