strfmon: reduce unnecessary snprintf. No need for the snprintf/asprintf dance; use fixed width formats. Obtained from: NetBSD (CVS rev. 1.8)

Implement xlocale APIs from Darwin, mainly for use by libc++. This adds a

load of _l suffixed versions of various standard library functions that use the global locale, making them take an explicit locale parameter. Also adds support for per-thread locales. This work was funded by the FreeBSD Foundation. Please test any code you have that uses the C standard locale functions! Reviewed by: das (gdtoa changes) Approved by: dim (mentor)

http://www.freebsd.org/cgi/query-pr.cgi?pr=bin/143350 Empty string test gone wrong. Testing this requires that you have a locale that has the sign string unset but has int_n_sign_posn set (the default locale falls through to use "()" around negative numbers which is probably another bug). I created that setup by hand and indeed without this fix negative numbers are put out as positive numbers (doesn't fall through to use "-" as default indicator). Unfixed example in nl_NL.ISO8859-1 with lc->negative_sign set to empty string: strfmon(buf, sizeof(buf), "%-8i", -42.0); ==> example2: 'EUR 42,00' 'Eu 42,00' Fixed: example2: 'EUR 42,00-' 'Eu 42,00-' This file and suggested fix are identical in at least freebsd-8. Backport might be appropriate but some expert on locales should probably have a look at us defaulting to negative numbers in parenthesis when LC_* is default. That doesn't look right and is not what other OSes are doing. PR: 143350 Submitted by: Corinna Vinschen Reviewed by: bug reporter submitted, tested by me
