* include/bits/codecvt.h (codecvt<char, char, mbstate_t>): friend class
std::messages<char>.
(codecvt<wchar_t, char, mbstate_t>): friend class
std::messages<wchar_t>.
* config/locale/gnu/messages_member.h
(messages<char>::do_open): Specialized.
(messages<char>::do_close): Likewise.
(messages<wchar_t>::do_open): Likewise.
(messages<wchar_t>::do_close): Likewise.
* config/locale/gnu/messages_member.cc:
(messages<char>::do_open): Implement. Use bind_textdomain_codeset based
on codecvt<char, char, mbstate_t>._M_c_locale_codecvt code set. Use
internal cache to keep opened domain name with locale information.
(messages<wchar_t>::do_open): Likewise with
codecvt<wchar_t, char, mbstate_t>.
(messages<char>::do_close): Implement. Clean cache information.
(messages<wchar_t>::do_close): Likewise.
(get_glibc_msg): New. Use dgettext rather than gettext using cached
domain name associated to catalog id.
(messages<char>::do_get): Use latter.
(messages<wchar_t>::do_get): Likewise and use also cached locale
codecvt<wchar_t, char, mbstate_t> facet to convert wchar_t default
value to char and the result back to wchar_t.
* testsuite/22_locale/messages/13631.cc: New.
* testsuite/22_locale/messages/members/char/2.cc: Use also fr_FR locale
for charset conversion to get the expected accented character.
