glamor: glamor_debug.h: drop unused AbortServer() declaration
This really looks like a leftover from b861aad8.
In any case, if that function shall become part of extension/driver API, it should be declared with _X_EXPORT in some suitable header file - locally declaring extern really isn't a good idea and just an invitation for subtle bugs.
