Carlos O'Donell 2ab8b74567 localedef: Update LC_MONETARY handling (Bug 28845) 
ISO C17, POSIX Issue 7, and ISO 30112 all allow the char*
types to be empty strings i.e. "", integer or char values to
be -1 or CHAR_MAX respectively, with the exception of
decimal_point which must be non-empty in ISO C. 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
<U002E> 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.

warning, and error behaviour of LC_MONETARY. They are ISO/IEC TR 30112,
ISO/IEC 9899:2018 (ISO C17), and POSIX.1-2017. Within 30112 we have the
definition of a standard i18n FDCC-set, which for LC_MONETARY has the
following default values:
int_curr_symbol ""
currency_symbol ""
mon_decimal_point "<U002C>" i.e. ","
mon_thousand_sep ""
mon_grouping "\177" i.e. CHAR_MAX
positive_sign ""
negative_sign "<U002E>" i.e. "."
int_frac_digits -1
frac_digits -1
p_cs_precedes -1
p_sep_by_space -1
n_cs_precedes -1
n_sep_by_space -1
p_sign_posn -1
n_sign_posn -1
Under 30112 a keyword that is not provided implies an empty string ""
for string values or a -1 for integer values, and indicates the value
is unspecified with no default implied. No errors are considered.
The exception is mon_grouping which is a string with a terminating
CHAR_MAX.
For POSIX Issue 7 we have:
https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap07.html
and again values not provided default to "" or -1, and indicate the value
is not available to the locale. The exception is mon_grouping which is
a string with a terminating CHAR_MAX. For the POSIX locale the values of
LC_MONETARY should be:
int_curr_symbol ""
currency_symbol ""
mon_decimal_point ""
mon_thousands_sep ""
mon_grouping "\177" i.e. CHAR_MAX
positive_sign ""
negative_sign ""
int_frac_digits -1
frac_digits -1
p_cs_precedes -1
p_sep_by_space -1
n_cs_precedes -1
n_sep_by_space -1
p_sign_posn -1
n_sign_posn -1
int_p_cs_precedes -1
int_p_sep_by_space -1
int_n_cs_precedes -1
int_n_sep_by_space -1
int_p_sign_posn -1
int_n_sign_posn -1
Like with 30112, POSIX also considers no error if the keywords are
missing, only that if the cateory as a whole is missing the referencing
of the category results in unspecified behaviour.
For ISO C17 there is no default value provided, but the localeconv
specification in 7.11.2.1 admits that members of char * type may point
to "" to indicate a value is not available or is of length zero.
The exception is decimal_point (not mon_decimal_point) which must be a
defined non-empty string. The values of char, which are generally
mapped to integer values in 30112 and POSIX, must be non-negative
numbers that map to CHAR_MAX when a value is not available in the
locale.
In ISO C17 for the "C" locale all values are empty strings "", or
CHAR_MAX, with the exception of decimal_point which is "." (defined
in LC_NUMERIC). ISO C17 makes no exception for mon_grouping like
30112 and POSIX, but a value of "" is functionally equivalent to
"\177" since neither defines a grouping (though the latter terminates
the grouping).
Lastly, we must consider the legacy C/POSIX locale that implemented
as a builtin in glibc and wether a default value mapping to the
C/POSIX locale may benefit the user from a compatibility perspective.
Thus given 30112, POSIX, ISO C, and the builtin C/POSIX locale we
need to pick appropriate defaults below. */
/* The members of LC_MONETARY are handled in the order of their definition
in locale/categories.def. Please keep them in that order. */
/* The purpose of TEST_ELEM is to define a default value for the fields
in the category if the field was not defined in the cateory. If the
category was present but we didn't see a definition for the field then
we also issue a warning, otherwise the only warning you get is the one
earlier when a default category is created (completely missing category).
This missing field warning is glibc-specific since no standard requires
this warning, but we consider it valuable to print a warning for all
missing fields in the category. */
