PR#752: make clean is more aggressive

Changes with Apache 1.2.1

  *) "make clean" at the top level now removes *.o.  [Dean Gaudet] PR#752

  *) Don't serve file system objects unless they are plain files, symlinks,

     or directories.  This prevents local users from using pipes or

     named sockets to invoke programs for an extremely crude form of

     CGI.  [Dean Gaudet]

  *) HeaderName and ReadmeName were settable in .htaccess and could

     contain "../" allowing a local user to "publish" any file on the

     system.  No slashes are allowed now.  [Dean Gaudet]

  *) It was possible to violate the symlink Options using mod_dir (headers,

     readmes, titles), mod_negotiation (type maps), or mod_cern_meta

     (meta files).  [Dean Gaudet]

  *) Update Unixware support for 2.1.2.  [Lawrence Rosenman <ler@lerctr.org>]
