[PATCH] strfmon_l: Use specified locale for number formatting [BZ #19633]

[Florian Weimer]

strfmon_l incorrectly applied global locale settings to number
formatting because printf_fp could only look at the global locale.

The new test tries to exercise the (in)dependence of a few LC_MONETARY
properties.  Some of the locales I used for testing might be buggy.

I introduced new helper macros to index the locale data in a locale_t
object.  A future cleanup opportunity is the _NL_CURRENT redefinition in
strfmon_l itself.  __guess_grouping should be moved out of printf_fp.c,
with a proper prototype in a header file.

I saw some ldbl_hidden_def thing.  I fear it is used by ld-as-a-functor
magic to work around the lack of templates in C.  What I did should
hopefully be safe.

Martin, does this patch match what you had in mind?

Thanks,
Florian
