It needs to load some functions dynamically using the dynlib mechanism.

These functions cannot be directly linked into the Emacs binary, since
doing that will prevent the binary from functioning on systems that have
GTK, but not both Xlib and libwayland-client.  They return the file
descriptor of a display connection, so that we can initialize SIGIO for
it and use interrupt-based input.

Thanks.
