* eval.c (op_unwind_protect): Fixed uninitialized variable

warning.
(eval_init): New functions registered: typeof and vector functions,
as well as length_list.

* lib.c (length): Function renamed to length_list, because it is
list specific.
(length_vec, size_vec, vector_list): New functions.
(length): New function, generic over lists, vectors and strings.

* lib.h (length_list, length_vec, size_vec, vector_list): Declared.

* match.c (h_var, h_fun, robust_length, v_deffilter, v_fun): Use
length_list instead of length.

* parser.l: Introduced # token.

* parser.y (vector): New nonterminal.
(expr): vector is a kind of expr.
(chrlist): Bugfix: single-character syntax was not working;
for instance #\x to denote the charcter x.
(lit_char_helper): Use length_list instead of length.

* stream.c (string_in_get_line): Bugfix: this was using
the wrong length function: length was being applied to a string.
The genericity of length makes that correct now, but changing
to length_str anyway.

* txr.1: Blank sections created for functions. Vector syntax
documented.
