cpplib.c: Rename make_definition to cpp_define.

* cpplib.c:  Rename  make_definition to cpp_define.
* cpplib.c (special_symbol):  For T_SPECLINE, calculate __LINE__
in enclosing file buffer, not current buffer (if macro expanding).
(cpp_get_token):  Fix thinko (in code for chopping unneeded space).
