* ld.texinfo (Input Section Basics): Clarify ordering of output
sections.
* ldlang.c (callback_t): Add wildcard_list param.
(walk_wild_section): Remove "section" param. Rewrite for
lang_wild_statement_type change. Remove unique_section_p test.
(walk_wild_file): Remove "section" param.
(walk_wild): Remove "section" and "file" params.
(lang_gc_wild): Likewise.
(wild): Likewise. Modify for lang_wild_statement_type change.
(wild_sort): Likewise. Add "sec" param.
(gc_section_callback): Likewise.
(output_section_callback): Likewise. Do unique_section_p test.
(map_input_to_output_sections): Modify call to wild.
(lang_gc_sections_1): Likewise.
(print_wild_statement): Modify for lang_wild_statement_type
change.
(lang_add_wild): Replace filename, filenames_sorted param with
filespec. Replace section_name, sections_sorted,
exclude_filename_list with section_list.
* ldlang.h (lang_add_wild): Here too.
(lang_wild_statement_type): Replace section_name, sections_sorted,
and exclude_filename_list with section_list.
* ldgram.y (current_file): Delete.
(%union): Add wildcard_list.
(file_NAME_list): Set type to wildcard_list. Build a linked list
rather than calling lang_add_wild for each entry.
(input_section_spec_no_keep): Call lang_add_wild here instead.
* ld.h (struct wildcard_list): Declare.
* mri.c (mri_draw_tree): Modify to suit new lang_add_wild.
