The C function nullp is being renamed to null, and the rarely

used global variable null which holds a symbol becomes null_s.

A new macro called nilp is added that more efficiently checks whether
an object is nil, producing a C boolean value rather than t or nil.

Most of the uses of nullp in the codebase just become the more
streamlined nilp.

* debug.c (show_bindings): nullp to nilp

* eval.c (lookup_var, lookup_var_l, lookup_fun, lookup_sym_lisp1,
do_eval, expand_qquote, expand_quasi, expand_op): nullp to nilp.
(op_modplace): nullp to null.
(eval_init): Update registration of null and not from C function
nullp to null.

* filter.c (trie_compress, html_hex_continue): nullp to nil.
(filter_string_tree): null to null_s.

* hash.c (hash_next): nullp to nilp.

* lib.c (null): Variable renamed to null_s.
(code2type): null to null_s.
(lazy_flatten_scan, chainv, lazy_str, lazy_str_force_upto,
obj_print, obj_pprint):
nullp to nilp.
(obj_init): null to null_s; nullp to null.

* lib.h (null): declaration changed to null_s.
(nullp): Inline function renamed to null.
(nilp): New macro.

* match.c (do_match_line): nullp to nilp.

* rand.c (make_random_state): Likewise.

* regex.c (compile_regex): Likewise.

 	* parser.y: Bugfix, I think. :) We do not need to call the expander
 	for a Lisp expression in a quasistring, and doing so leads to a
 	potentially incorrect double expansion because the whole thing
