Add libneon-gnutls support library to allow use of external signing

callback with GnuTLS:

* src/lib_gnutls.c, src/ne_gnutls.h, neon-gnutls.pc.in: New files.

* src/ne_privssl.h (struct ne_ssl_context_s): Add sign_func, sign_data
  fields.

* macros/neon.m4 (NEON_SSL): Define NE_SSL_LIBNAME; check for
  gnutls_sign_callback_set, add new exports NE_SSL_CFLAGS and
  NE_LIBSSL_LTFLAGS.  Export NEON_LIBEXT in place of NEON_TARGET,
  NE_LIBNEON_LTFLAGS in place of NEON_LINK_FLAGS;

* src/Makefile.in: Add and adjust targets to build libneon-gnutls iff
  configured with GnuTLS support.

* Makefile.in (install-lib-ssl-no, install-lib-ssl-gnutls): New
  targets.

* neon-config.in: Add --la-file=gnutls, --cflags=gnutls support.

* src/ne_socket.c (ne_sock_connect_ssl): Set up the sign_func callback
  if non-NULL.

* configure.in: Adjust for NEON_LINK_FLAGS rename.  Define
  NE_LIBSSL_LTFLAGS.  Generate neon-gnutls.pc.
