* ecoff.c: First cut at new style of linker backend for

ECOFF--added a bunch of functions.  Also:
	(ecoff_sec_to_styp_flags): Set flags for .pdata and .xdata.
	(ecoff_slurp_symbolic_header): New function.
	(ecoff_slurp_symbolic_info): Call ecoff_slurp_symbolic_header.
	(ecoff_compute_reloc_file_positions): New function.
	(ecoff_set_section_contents): Get out quickly if count is zero.
	Check errors better.
	(ecoff_write_object_contents): Put .xdata section in data segment.
	Call ecoff_compute_reloc_file_positions.  Don't output relocs or
	external symbols if outsymbols is NULL.
	(ecoff_bfd_final_link): Completely rewritten.
	* libecoff.h: Include bfdlink.h.
	(struct ecoff_backend_data): Add relocate_section field.
	(ecoff_data_type): Add sym_hashes and symndx_to_section fields.
	(struct ecoff_link_hash_entry): Define.
	(struct ecoff_link_hash_table): Define.
	(ecoff_bfd_link_add_symbols): Declare as function, not macro.
	(ecoff_bfd_link_hash_table_create): Likewise.
	* ecofflink.c (bfd_ecoff_debug_one_external): New function.
	(bfd_ecoff_debug_externals): Call bfd_ecoff_debug_one_external.
	* bfd-in.h (bfd_ecoff_debug_one_external): Declare.
	* bfd-in2.h: Rebuilt.
	* coff-alpha.c (alpha_howto_table): Mark BRADDR as
	partial_inplace, and set the src_mask to 0x1fffff.
	(alpha_ecoff_get_relocated_section_contents): Remove unused
	variable gp_warned.
	(alpha_convert_external_reloc): New static function.
	(alpha_relocate_section): New static function.
	(alpha_ecoff_backend_data): Initialize relocate_section field.
	* coff-mips.c (mips_relocate_refhi): New static function.
	(mips_relocate_section): New static function.
	(mips_ecoff_backend_data): Initialize relocate_section field.
