[PATCH wayland v3] tests: add an headers test

Giulio Camuffo giuliocamuffo at gmail.com
Thu May 21 10:43:13 PDT 2015 

This test checks that the protocol and library headers include only what
they are supposed to include. That is, that the core headers do not
include the protocol headers and that the core protocol headers do not
include the non core library headers.
The build process now generates core protocol headers, but they are only
used in the test and don't get installed.
---

v3: generate the core headers specifically for the test. for real
