Simplify lexer.  Implement --enable-mapped-location support.

* jcf-parse.c (parse_class_file):  Use linemap_line_start.
(parse_source_file_1): Pass filename as extra parameter, so we can call
linemap_add and set input_location here, rather than in both callers.
(read_class): Pass copied filename to parse_source_file_1.
Don't initialize wfl_operator - only needed for source compilation.

Create a list of TRANSLATION_UNIT_DECL.
(current_file_list):  Is now a TRANSLATION_UNIT_DECL chain.  The
reason is so we can set a DECL_SOURCE_LOCATION for each file.
