Continuing implementation of buffers.

* Makefile (OBJS): New objects itypes.o and buf.o.

* buf.c, buf.h: New files.

* itypes.c, itypes.h: New files.

* lib.c (obj_print_impl): Handle BUF via buf_print and
buf_pprint.
(init): Call itypes_init and buf_init.

* parser.h (end_of_buflit): Declared.

* parser.l (BUFLIT): New exclusive state.
(grammar): New rules for recognizing start of buffer
literal and its interior.
(end_of_buflit): New function.

* parser.y (HASH_B_QUOTE): New token.
(buflit, buflit_items, buflit_item): New nonterminals
and corresponding grammar rules.
(i_expr, n_expr): These symbols now generate a buflit;
a buffer literal is a kind of expression.
(yybadtoken): Handle HASH_B_QUOTE case.
