[PATCH wayland] tests: add an headers test

[Bill Spitzak]

Please don't duplicate the functions in multiple headers!

You could achieve the same result this way so that there is only one 
copy of each function in the headers:

wayland-client-protocol-core.h =
   (the same as you have it, generated by wayland-scanner -c)

wayland-client-protocol.h =
   #include <wayland-client-protocol-core.h>
   #include <wayland-client.h>

However this really is a mess and these extra header files do nothing 
except confuse anybody trying to learn wayland. Would vastly prefer 
making -c the default and requiring the *VERY FEW* programs that no 
longer compile to be patched.
