Add internal implementations for argp.h, err.h, and error.h functions

Since the introduction of explicit flags in the internal implementation
of the printf family of functions, the 'mode' parameter can be used to
select which format long double parameters have (with the mode flag:
PRINTF_LDBL_IS_DBL).  This patch uses this feature in the implementation
of some functions in argp.h, err.h, and error.h (only those that take a
format string and positional parameters).  Future patches will add
support for 'nldbl' and 'ieee128' versions of these functions.

Tested for powerpc64le and x86_64.

+	* argp/argp-help.c (__argp_error_internal): New function,
+	renamed from __argp_error, but that takes a 'mode_flags'
+	parameter to control the format of long double parameters.
+	(__argp_error): Converted into a call __argp_error_internal.
+	(__argp_failure_internal): New function, renamed from
+	__argp_failure, but that takes a 'mode_flags' parameter.
+	(__argp_failure): Converted into a call __argp_failure_internal.
+	* misc/err.c (__vwarnx_internal): New function, renamed from
+	vwarnx, but that takes a 'mode_flags' parameter.
+	(vwarnx): Converted into a call to __vwarnx_internal.
+	(__vwarn_internal): New function, renamed from vwarn, but that
+	takes a 'mode_flags' parameter.
+	(vwarn): Converted into a call to __vwarn_internal.
+	* misc/error.c (error_tail): Add 'mode_flags' parameter. Update
+	call to __vfxprintf with 'mode_flags'.
+	(__error_internal): New function, renamed from error, but that
+	takes a 'mode_flags' parameter.
+	(error): Converted into a call to __error_internal.
+	(__error_at_line_internal): New function, renamed from
+	error_at_line, but that takes a 'mode_flags' parameter.
+	(error_at_line): Converted into a call to
+	__error_at_line_internal.
+	* include/stdio.h (__vfxprintf): Add mode_flags parameter.
+	* stdio-common/fxprintf.c (locked_vfxprintf, __vfxprintf):
+	Likewise.
