Remove unnecessary casts of NULL
I noticed some unnecessary casts of NULL. This removes all the unnecessary ones, leaving only ones where we must ensure that NULL has pointer type for passing through varargs. I removed a couple of useless casts of 0 that I noticed while writing this. Tested by rebuilding. gdb/ChangeLog 2019-06-16 Tom Tromey <tom@tromey.com> * valops.c (value_cast, value_slice): Remove unnecessary cast. * breakpoint.c (stopin_command, stopat_command) (until_break_command, decode_location_default): Remove unnecessary cast. * utils.c (subset_compare): Remove unnecessary cast. * ada-lang.c (ada_update_initial_language): Remove unnecessary cast. * linespec.c (decode_line_with_last_displayed): Remove unnecessary cast. * infcmd.c (path_command): Remove unnecessary cast. * coffread.c (decode_type): Remove unnecessary cast. * xcoffread.c (read_xcoff_symtab): Remove unnecessary cast. * mipsread.c (mipscoff_symfile_read): Remove unnecessary cast. * tui/tui-stack.c (tui_show_locator_content) (tui_show_frame_info): Remove unnecessary cast. * tui/tui-win.c (tui_scroll_forward_command) (tui_scroll_backward_command, tui_set_focus, tui_set_win_height) (parse_scrolling_args): Remove unnecessary cast. * tui/tui-data.c (init_win_info, tui_del_window) (tui_free_window, tui_del_data_windows, tui_free_data_content) (free_content_elements): Remove unnecessary cast. * tui/tui-windata.c (tui_first_data_item_displayed): Remove unnecessary cast. * tui/tui-source.c (tui_set_source_content) (tui_vertical_source_scroll): Remove unnecessary cast. * tui/tui-layout.c (tui_default_win_height): Remove unnecessary cast. * tui/tui-io.c (tui_initialize_io): Remove unnecessary cast. * tui/tui-regs.c (tui_display_registers_from) (tui_display_register): Remove unnecessary cast. * tui/tui-wingeneral.c (tui_refresh_win, tui_delete_win) (tui_unhighlight_win, tui_highlight_win, tui_make_window) (make_visible): Remove unnecessary cast. * tui/tui-winsource.c (tui_erase_source_content) (tui_update_breakpoint_info, tui_set_exec_info_content): Remove unnecessary cast. * ax-gdb.c (agent_command_1): Remove unnecessary cast. * cli/cli-setshow.c (cmd_show_list): Remove unnecessary cast. * stabsread.c (read_type, read_array_type, read_range_type): Remove unnecessary cast. * mdebugread.c (mdebug_build_psymtabs): Remove unnecessary cast.
