+ Port memory-full checking to GnuTLS 3.3
+ Instead of using gnutls_global_set_mem_functions, check every call
+ to a GnuTLS function that might return an indication of memory
+ exhaustion. Suggested by Dmitry Antipov in:
+ http://lists.gnu.org/archive/html/emacs-devel/2014-12/msg02056.html
+ * gnutls.c (gnutls_global_set_mem_functions) [WINDOWSNT]: Remove.
+ (init_gnutls_functions): Do not load gnutls_global_set_mem_functions.
+ (fn_gnutls_global_set_mem_functions) [!WINDOWSNT]: Remove.
+ All uses removed.
+ (check_memory_full): New function.
+ (emacs_gnutls_handshake, emacs_gnutls_handle_error)
+ (gnutls_make_error, gnutls_certificate_details, Fgnutls_peer_status)
+ (Fgnutls_boot): Use it.
+ (emacs_gnutls_global_init): Avoid gnutls_global_set_mem_functions.
