Introduce gdb_argv, a class wrapper for buildargv
This introduces gdb_argv, a class wrapping an "argv" pointer; that is, a pointer to a NULL-terminated array of char*, where both the array and each non-NULL element in the array are xmalloc'd. This patch then changes most users of gdb_buildargv to use gdb_argv instead. ChangeLog 2017-08-03 Tom Tromey <tom@tromey.com> * utils.h (struct gdb_argv_deleter): New. (gdb_argv): New class. * utils.c (gdb_argv::reset): New method. * tracepoint.c (delete_trace_variable_command): Use gdb_argv. * tracefile.c (tsave_command): Use gdb_argv. * top.c (new_ui_command): Use gdb_argv. * symmisc.c (maintenance_print_symbols) (maintenance_print_msymbols, maintenance_expand_symtabs): Use gdb_argv. * symfile.c (symbol_file_command, generic_load) (remove_symbol_file_command): Use gdb_argv. * stack.c (backtrace_command): Use gdb_argv. * source.c (add_path, show_substitute_path_command) (unset_substitute_path_command, set_substitute_path_command): Use gdb_argv. * skip.c (skip_command): Use gdb_argv. Use gdb_buildargv. * ser-mingw.c (pipe_windows_open): Use gdb_argv. * remote.c (extended_remote_run, remote_put_command) (remote_get_command, remote_delete_command): Use gdb_argv. * remote-sim.c (gdbsim_load, gdbsim_create_inferior) (gdbsim_open): Use gdb_argv. * python/py-cmd.c (gdbpy_string_to_argv): Use gdb_argv. * psymtab.c (maintenance_print_psymbols): Use gdb_argv. * procfs.c (procfs_info_proc): Use gdb_argv. * interps.c (interpreter_exec_cmd): Use gdb_argv. * infrun.c (handle_command): Use gdb_argv. * inferior.c (add_inferior_command, clone_inferior_command): Use gdb_argv. * guile/scm-string.c (gdbscm_string_to_argv): Use gdb_argv. * exec.c (exec_file_command): Use gdb_argv. * cli/cli-cmds.c (alias_command): Use gdb_argv. * compile/compile.c (build_argc_argv): Use gdb_argv.
