Merge bfd_find_nearest_line variants

When bfd_find_nearest_line_discriminator was added, not enough care
was taken to ensure all targets had a proper definition of the function.
This patch cures that by merging bfd_find_nearest_line_discriminator
and bfd_find_nearest_line target implementations.

	PR 17481
	* aoutx.h (NAME (aout, find_nearest_line)): Add "discriminator_ptr"
	param, group "section" and "offset" params.  Zero discriminator.
	* bfd.c (bfd_find_nearest_line): Implement with new
	_bfd_find_nearest_line.
	(bfd_find_nearest_line_discriminator): Likewise.
	* coff-i386.c (_bfd_generic_find_nearest_line_discriminator): Don't
	define.

	adjust _bfd_dwarf2_find_nearest_line call.

	others.  Set discriminator.  Adjust call.
