sym_text_len existed to strip parameters out of the lookup name. Now
that that's handled by the lookup_name_info objects, the
sym_text/sym_text_len parameters are no longer necessary.
gdb/ChangeLog:
yyyy-mm-dd Pedro Alves <palves@redhat.com>
* ada-lang.c (ada_make_symbol_completion_list): Remove text and
text_len locals and don't pass them down.
* symtab.c (completion_list_add_name): Remove
sym_text/sym_text_len parameters and adjust.
(completion_list_add_symbol, completion_list_add_msymbol)
(completion_list_objc_symbol, completion_list_add_fields)
(add_symtab_completions): Likewise.
(default_collect_symbol_completion_matches_break_on)
(collect_file_symbol_completion_matches): Remove sym_text_len
local and don't pass it down.
* symtab.h (completion_list_add_name): Remove
sym_text/sym_text_len parameters.
