dbxout.c (asmfile): Delete. 

* dbxout.c (asmfile): Delete.  All uses changed to asm_out_file.
	(DBX_BLOCKS_FUNCTION_RELATIVE, DBX_LINES_FUNCTION_RELATIVE):
	Default to 0.
	(dbxout_source_line): Use DBX_OUTPUT_SOURCE_LINE when defined.
	When it is not, but DBX_LINES_FUNCTION_RELATIVE is true, emit
	an internal label and an N_SLINE .stabn whose value is the
	difference between that label and the function entry label.
	(dbxout_finish): If DBX_OUTPUT_MAIN_SOURCE_FILE_END is not defined,
	but DBX_OUTPUT_NULL_N_SO_AT_MAIN_SOURCE_FILE_END is, emit a
	label and an N_SO stab with an empty string referring to it.
	(dbx_output_lbrac, dbx_output_rbrac): Use if statement instead
	of #ifdef directive to test DBX_BLOCKS_FUNCTION_RELATIVE.
	(dbxout_type_methods, dbxout_symbol): Remove #if 0 block.
	(dbxout_prepare_symbol): Remove #ifdef WINNING_GDB block, this
	macro is never defined.
	* sdbout.c (sdbout_source_line_counter): Delete.
	(PUT_SDB_SRC_FILE): Delete.  Uses replaced with sole definition.
	(sdbout_source_line): Use SDB_OUTPUT_SOURCE_LINE, which takes
	only two arguments.
	* xcoffout.c (ASM_OUTPUT_SOURCE_LINE): Rename ASM_OUTPUT_LINE.

	* config/dbxcoff.h, config/dbxelf.h: Remove unncessary #undefs.
	* config/c4x/c4x.h, config/pa/pa.h: Remove unnecessary macro
	definitions (identical to default).
	* config/darwin.h, config/dbxcoff.h, config/dbxelf.h, config/ptx4.h
	* config/h8300/coff.h, config/pa/som.h, config/sh/elf.h:

	* config/alpha/alpha-protos.h: Don't prototype alpha_output_lineno.
	* config/alpha/alpha.c: Move declaration of num_source_filenames up.
	(alpha_start_function): Use SDB_OUTPUT_SOURCE_LINE.
