[patch v3 04/16] source, disasm: optionally prefix source lines with filename

[markus.t.metzger@intel.com]

From: Markus Metzger <markus.t.metzger@intel.com>

Add respective flags to print_source_lines () and gdb_disassembly () to prefix
the source line with its file name.

2012-08-14 Markus Metzger <markus.t.metzger@intel.com>

	* disasm.h (DISASSEMBLY_FILENAME): New macro.
	* disasm.c (do_mixed_source_and_assembly): Pass filename flag on to
	print_source_lines ().
	* symtab.h (PRINT_SOURCE_LINES_FILENAME): New print source lines flag.
	* source.c (print_source_lines_base): Prefix source line with filename if
	PRINT_SOURCE_LINES_FILENAME flag is set.
