More use of std::vector in linespec.c
This changes some spots in linespec.c to take a std::vector. This patch spilled out to objc-lang.c a bit as well. This change allows for the removal of some cleanups. ChangeLog 2018-04-05 Tom Tromey <tom@tromey.com> * utils.c (compare_strings): Remove. * utils.h (compare_strings): Remove. * objc-lang.h (find_imps): Update. * objc-lang.c (find_methods): Take a std::vector. (uniquify_strings, find_imps): Likewise. * linespec.c (find_methods): Take a std::vector. (decode_objc): Use std::vector. (add_all_symbol_names_from_pspace, find_superclass_methods): Take a std::vector. (find_method, find_function_symbols): Use std::vector.
