connection: Add a function to parse WAYLAND_DEBUG tokens

Add a new function, wl_check_env_token, to scan for a token in a
comma-separated string.

Change wl_display_create in wayland-server.c and
wl_display_connect_to_fd in wayland-client.c to use that instead of a
simple substring search.

This means that WAYLAND_DEBUG will accept a value like "client,server"
but not "clientserver". But, this will make it easier to add other
tokens without worrying about overlap between them.
