- initial attempt at consolidating ssl-related code into netutils.{c,h}

- added some #ifdefs to common.h and netutils.h to prevent multiple
  inclusions (as netlibs now includes common.h)
- all ssl plugins (tcp/http/smtp) compile cleanly against gnutls, though
  certificate checking still needs to be done.
- modified configure script so you can also explicitly say "without-gnutls"
  too (otherwise if you disable openssl you have no way of disabling
  gnutls too)
