* lisp.h (enum Lisp_Misc_Type): Del Lisp_Misc_Some_Buffer_Local_Value.

(XMISCANY): New macro.
(XMISCTYPE): Use it.
(struct Lisp_Misc_Any): New type.
(union Lisp_Misc): Use it.
(struct Lisp_Buffer_Local_Value): Add `local_if_set' bit.
* data.c (Fboundp, store_symval_forwarding, swap_in_global_binding)
(find_symbol_value, set_internal, default_value, Fset_default)
(Fmake_variable_buffer_local, Fmake_local_variable)
(Fkill_local_variable, Fmake_variable_frame_local, Flocal_variable_p)
(Flocal_variable_if_set_p, Fvariable_binding_locus):
The SOME_BUFFER_LOCAL_VALUEP distinction is replaced by local_if_set.
* alloc.c (allocate_buffer): Set the size and tag.
(allocate_misc, mark_maybe_object, mark_object, survives_gc_p):
Use XMISCANY.
(die): Follow the GNU convention for error messages.
* print.c (print_object): SOME_BUFFER_LOCAL_VALUEP -> local_if_set.
* buffer.c (Fget_buffer_create, Fmake_indirect_buffer): Don't set the
tag any more.
(set_buffer_internal_1):
* frame.c (store_frame_param):
* eval.c (specbind):
* xdisp.c (select_frame_for_redisplay): Drop SOME_BUFFER_LOCAL_VALUEP.
