This pointer is the first argument received by callbacks, and the existing argument "data" is now automatically freed by WeeChat when the object containing the callback is removed. With this new pointer, the linked list of callbacks in scripts has been removed. This will improve speed of scripts (using a lot of hooks), reduce memory used by scripts and reduce time to unload scripts. Following functions are affected in the C API: * exec_on_files * config_new * config_new_section * config_new_option * hook_command * hook_command_run * hook_timer * hook_fd * hook_process * hook_process_hashtable * hook_connect * hook_print * hook_signal * hook_hsignal * hook_config * hook_completion * hook_modifier * hook_info * hook_info_hashtable * hook_infolist * hook_hdata * hook_focus * unhook_all_plugin * buffer_new * bar_item_new * upgrade_new * upgrade_read
