a new api feature for inclusion of static files into server's binary

one api new function:
        libwebsockets_serve_http_bin(
                struct libwebsocket_context *context,
                struct libwebsocket *wsi,
                const unsigned char *bin, size_t bin_size,
                const char *content_type);

demo in test-server updated:
        a new executable is compiled "test-server-extpoll-embed"
        it embeds all necessary external files needed to run alone

added source: test-server/rawc.c
        a simple ansi-c program that generates source files
        from any number of binary files

(tested only under ubuntu 12.04/precise)
