[patch 3/9] Code cleanup: Renaming to "fullname" for expand

[Jan Kratochvil <jan dot kratochvil at redhat dot com>]

Hi,

just a mechanical part to call "fullname" the kind of content which comes from
symtab_to_fullname.

This part is incomplete, for example this part is fixed in future patches:
read_psymtabs_with_filename:
-      if (filename_cmp (filename, p->filename) == 0)
+      if (filename_cmp (fullname, p->filename) == 0)
(p->filename is not yet a fullname here)


Thanks,
Jan

	Code cleanup.
	* dwarf2read.c (dw2_expand_symtabs_with_filename): Rename to ...
	(dw2_expand_symtabs_with_fullname): ... here.  Rename parameter
	filename to fullname.  Rename variable this_name to this_fullname.
	Lowercase FILENAME_CMP call.
	(dw2_find_symbol_file): New comment for the returned string.
	(dwarf2_gdb_index_functions): Rename the function to
	dw2_expand_symtabs_with_fullname.
	* psymtab.c (read_psymtabs_with_filename): Rename to ...
	(read_psymtabs_with_fullname): ... here.  Rename parameter filename to
	fullname.
	(psym_functions): Rename the function to read_psymtabs_with_fullname.
	* symfile.h (struct quick_symbol_functions): Rename field
	expand_symtabs_with_filename to expand_symtabs_with_fullname and its
	parameter filename to fullname.  Document returned string meaning for
	find_symbol_file.
	* symtab.c (find_line_symtab): Rename the called function to
	expand_symtabs_with_fullname.
