functional if libcurl is built against OpenSSL

a "dummy" just to get things as fixed as possible in case we ever get the urge
to change this to actually mean something.

  works in C mode atm (http://curl.haxx.se/mail/lib-2008-02/0267.html ,
  http://curl.haxx.se/mail/lib-2008-02/0292.html )

usage

test code. Thanks to his curl_easy_setopt() typechecker work...

replaced fstat() with stat() call and bail out if local file not found.

moved sample program defines into separate Makefile.inc so that other makefiles can pick up the defines from there.

  get a fresh one downloaded and created with 'make ca-bundle' or you can get
  one from here => http://curl.haxx.se/docs/caextract.html if you want a fresh
  new one extracted from Mozilla's recent list of ca certs.

  The configure option --with-ca-bundle now lets you specify what file to use
  as default ca bundle for your build. If not specified, the configure script
  will check a few known standard places for a global ca cert to use.

instead of downloading it from the curl site

ca-bundle.crt file as outdated and in need for replacement by anyone who wants
to verify modern peers as the one we have is from year 2000!

HTTPS sites with OpenSSL-enabled libcurl (and pthreads) and thus do the
thread-locking and things openssl-style.

51.Kevin Reed's reported problem with a proxy when doing CONNECT and it
  wants NTLM and close the connection to the initial CONNECT response:

  crash!

release but hopefully they'll all be fixed in 7.18.1...

status.  It uses Gtk+ to make a smooth pulse. Written by Jud Bishop

silly code left from when we switched to let the multi handle "hold" the dns
cache when using the multi interface... Of course this only triggered when a
certain function call returned error at the correct moment.

--keepalive-time to curl to set the keepalive probe interval. I also took
the opportunity to rename the recently added no-keep-alive option to
no-keepalive to keep a consistent naming and to avoid getting two dashes in
these option names. Eric also provided an update to the man page for the new
option.
