Collect characters belonging to this set into tokens (as specified by
the SRFI), instead of splitting at these characters. Default to an
equivalent of char-set:graphic instead of everything-but-whitespace.

internal definitions.
(list-tabulate, iota): check for bad arguments that otherwise
give weird output.
(filter): replaced with a tail-recursive version.
(remove): implement using filter, to make it tail-recursive.
srfi-11.scm, srfi-14.scm, srfi-16.scm: Move module the system
directives `export', `export-syntax', `re-export' and
`re-export-syntax' into the `define-module' form. This is the
recommended way of exporting bindings.

accounting for the (char-set-union cs2...) in the spec. i.e.,
(char-set-diff+intersection a) -> copy-of-a, empty-set
and the following are equivalent:
(char-set-diff+intersection a (char-set #\a) (char-set #\b))
(char-set-diff+intersection a (char-set #\a #\b))
(scm_char_set_xor_x): disabled the side-effecting code, since it
gives inconsistent results to scm_char_set_xor for the case
(char-set-xor! a a a).
(scm_char_set_diff_plus_intersection_x): added cs2 argument, since
two arguments are compulsory in final spec. also similar changes
as for scm_char_set_diff_plus_intersection.
* srfi-14.h (scm_char_set_diff_plus_intersection_x): added cs2.
they occur in exactly one argument, but were included if they
occured an odd number of times >= 3, e.g, in (char-set-xor a a a)
where a is (char-set #\a). fix it with a "mask" array.
