Support arbitrary length fill patterns.

	* ldexp.h (etree_value_type): Add "str" field.
	(union etree_union): Add "str" to "value" struct.
	(exp_bigintop): Declare.
	(exp_get_fill): Declare.
	* ldexp.c: Include "safe-ctype.h".
	(exp_intop): Set value.str to NULL.
	(exp_bigintop): New function.
	(new_rel): Pass in "str", and set new.str from it.
	(new_rel_from_section): Set new.str to NULL.
	(fold_name): Adjust calls to new_rel.
	(exp_fold_tree): Likewise.
	(exp_get_fill): New function.
	* ldgram.y (struct big_int bigint, fill_type *fill): New.
	(INT): Returns a "bigint".  Adjust all code handling INTs.
	(fill_opt): Returns a "fill".
	(fill_exp): Split out of fill_opt, use for FILL.
	* ldlang.h (struct _fill_type): New.
	(fill_type): Move typedef to ldexp.h.
	(lang_output_section_statement_type): "fill" is now a pointer.
	(lang_fill_statement_type): Likewise.
	(lang_padding_statement_type): Likewise.
	(lang_add_fill): Now takes a "fill_type *" param.
	(lang_leave_output_section_statement): Likewise.
	(lang_do_assignments): Likewise.
	(lang_size_sections): Likewise.
	(lang_leave_overlay_section): Likewise.
	(lang_leave_overlay): Likewise.
	* ldlang.c: Include ldgram.h after ldexp.h.
	(lang_output_section_statement_lookup): Adjust for fill_type change.
	(print_fill_statement): Likewise.
	(print_padding_statement): Likewise.
	(insert_pad): Now takes a "fill_type *" arg.
	(size_input_section): Likewise.
	(lang_size_sections_1): Likewise.
	(lang_size_sections): Likewise.
	(lang_do_assignments): Likewise.
	(lang_add_fill): Likewise.
	(lang_leave_output_section_statement): Likewise.
	(lang_leave_overlay_section): Likewise.
	(lang_leave_overlay): Likewise.
	Adjust all callers of the above function.
	* ldlex.l: Include ldgram.h after ldexp.h.  Allow hex numbers
	starting with "0X" as well as "0x".  Return bigint.str for hex
	numbers starting with "0x" or "0X", zero bigint.str otherwise.
	Always use base 16 for numbers starting with "$".
	* ldmain.c: Include ldgram.h after ldexp.h.
	* ldwrite.c (build_link_order): Use bfd_data_link_order in place
	of bfd_fill_link_order.
	* pe-dll.c: Adjust lang_do_assignments calls.
	* emultempl/elf32.em: Likewise.
	* emultempl/hppaelf.em: Likewise.
	* emultempl/ppc64elf.em: Likewise.
	* emultempl/beos.em: Include ldgram.h after ldexp.h, adjust
	lang_add_assignment call.
	* emultempl/pe.em: Likewise.
