Use the type system instead of callers needing to know how the returned string's memory is supposed to be managed. gdb/ChangeLog: 2017-10-09 Pedro Alves <palves@redhat.com> * cp-support.c (cp_remove_params): Return a gdb::unique_xmalloc_ptr. Use bool. (overload_list_add_symbol): Adjust to use gdb::unique_xmalloc_ptr. * cp-support.h (cp_remove_params): Now returns a gdb::unique_xmalloc_ptr. * dwarf2read.c (find_slot_in_mapped_hash): Now returns bool. Adjust to cp_remove_params returning a gdb::unique_xmalloc_ptr. * psymtab.c (psymtab_search_name): Adjust to cp_remove_params returning a gdb::unique_xmalloc_ptr. (lookup_partial_symbol): Adjust to use gdb::unique_xmalloc_ptr. * stack.c (find_frame_funname): Adjust to cp_remove_params returning a gdb::unique_xmalloc_ptr.
