christos | Fix various vis/unvis issues:
- no need for all the weak symbols
- define a new _VIS_END flag for UNVIS_END so that there are no collisions
between and vis and unvis flags.
- add bound versions of the vis and unvis functions that take the length of
the destination buffer. Unlike the OpenBSD ones they return -1 or NULL if
the buffer is not large enough, instead of silently truncating.

martin | Pull up following revision(s) (requested by riastradh in ticket #485):
lib/libc/gen/vis.c: revision 1.76-1.86
tests/lib/libc/gen/t_vis.c: revision 1.10-1.14
vis(3): Avoid nonportable MIN in portable code.
vis(3) tests: Add xfail test for encoding overflow.
From Kyle Evans <kevans%FreeBSD.org@localhost>.
PR lib/57573
vis(3) tests: Expand tests and diagnostic outputs on failure.
PR lib/57573
vis(3) tests: Test another overflow edge case.
Related to PR lib/57573.
vis(3): Make maxolen unsigned size_t, not ssize_t.
It is initialized once either to *dlen, which is unsigned size_t, or
to wcslen(start) * MB_MAX_LEN + 1, and wcslen returns unsigned size_t
too. So there appears to have never been any reason for this to be
signed.
Part of PR lib/57573.
vis(3): Make mbslength unsigned.
Sprinkle assertions and comments justifying the proposition that it
would never go negative if signed.
Obviates need to worry about mblength > SSIZE_MAX.
Prompted by PR lib/57573.
vis(3): Avoid arithmetic overflow before calloc(3).
Prompted by PR lib/57573.
vis(3): Call wcslen(start) only once.
It had better not change between these two times!
Prompted by PR lib/57573.
vis(3): Avoid potential arithmetic overflow in maxolen.
Can't easily prove that this overflow is impossible, so let's add a
check.
Prompted by PR lib/57573.
vis(3): Fix main part of PR lib/57573.
From Kyle Evans <kevans%FreeBSD.org@localhost>.
vis(3): Fix one more buffer overrun in an edge case.
PR lib/57573
vis(3): Sort includes. No functional change intended.
Prompted by PR lib/57573.
vis(3): Need <stdint.h> for SIZE_MAX, per C standard.
From Kyle Evans <kevans%FreeBSD.org@localhost>.
Followup to PR lib/57573.
vis(3): Per KNF, sys/param.h comes before sys/types.h.
Which is nice because that's also lexicographic.
