Note that the defaults for mon_grouping vary, but are functionaly equivalent e.g. "\177" (no further grouping reuqired) vs. "" (no grouping defined for all groups). We include a broad comment talking about harmonizing ISO C, POSIX, ISO 30112, and the default C/POSIX locale for glibc. We reorder all setting based on locale/categories.def order. We soften all missing definitions from errors to warnings when defaults exist. Given that ISO C, POSIX and ISO 30112 allow the empty string we change LC_MONETARY handling of mon_decimal_point to allow the empty string. If mon_decimal_point is not defined at all then we pick the existing legacy glibc default value of i.e. ".". We also set the default for mon_thousands_sep_wc at the same time as mon_thousands_sep, but this is not a change in behaviour, it is always either a matching value or L'\0', but if in the future we change the default to a non-empty string we would need to update both at the same time. Tested on x86_64 and i686 without regressions. Tested with install-locale-archive target. Tested with install-locale-files target.

Removing '-c' from localedef invocation is the equivalent of using -Werror for localedef. The glibc locale sources should always be clean and free from warnings. We remove '-c' from both test locale generation and the targets used for installing locales e.g. install-locale-archive, and install-locale-files. Tested on x86_64 and i686 without regressions. Tested with install-locale-archive target. Tested with install-locale-files target.
