Remove unused external symbols.

* data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
* window.c (Qwindow_valid_p, decode_valid_window):
Now static, not extern.
* data.c (Qinterval): Remove; unused.
(syms_of_data): Do not define 'interval'.
* lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
* window.h (decode_valid_window):
