Remove references to global qe_state (#45)
* Remove references to global `qe_state`

Add `QEmacsState *qs` field in context and object structures:
- `QEditScreen`, `EditState` (renamed from `qe_state`), `QuitState`
- `WinWindow` (win32.c), `X11State` (x11.c), `QEArgs` (cmd line arguments)
- `CmdLineOptionDef::func_arg()`, `QEModeData`
- move `QEKeyContext` to `QEmacsState`

Pass `QEmacsState *qs` to configuration and state functions:
- all `module_xxx_init` and static `xxx_init` functions
- `QEDisplay::dpy_init()`, `qe_register_display()`, `screen_init()̀`
- `load_input_methods()`, `unload_input_methods()`
- `register_input_method()`, `find_input_method()`
- `find_resource_file()`, `open_resource_file()`
- `qe_find_current_binding()`, `qe_list_bindings()`
- `qe_register_mode()`, `qe_find_mode()`, `qe_find_mode_filename()`
- `qe_register_cmd_line_options()`, `set_user_option()`, `set_tty_charset()`

- `qe_register_completion()`, `qe_register_variables()`
- `eb_register_data_type()`, `parse_command_line()`
- `eb_trace_bytes()`, `qe_toggle_control_h()` (split from `do_toggle_control_h()`)
- `unget_key()`, `qe_grab_keys()`, `qe_ungrab_keys()`, `qe_key_process()`
- `eb_new()`, `eb_find()`, `eb_find_new()`, `eb_scratch()`, `eb_find_file()`
- `new_shell_buffer()` `macro_add_key()`, `clear_macro(), `stop_macro()`
- `check_window()`, `check_buffer()`, `qe_kill_buffer()`, `qe_get_history()`
- `qe_register_charset()`, `find_charset()`

Add error message handlers:
- add `QEDisplay::dpy_error()` method
- add `qe_cfg_error()`, use for all expression parsing errors
- pass opaque pointer to `css_error()`
- add `qe_put_error()` and `qe_dpy_error()`

Add context argument:
- always pass a non-null window pointer to `do_refresh()`, `new_help_buffer()`

d447da9ce0 Improve mouse support
Mouse:
- add `shift` state in all mouse events
- pass `QEmacsState *qs` to `qe_mouse_event`
- support non drag mouse events with `-m:2` command line option

  (should autorepeat, should have menu line at the top for scrolling up)
- cancel active search on mouse_goto
- do not mouse activate window if current active window is modal (popup or
  minibuf)
- handle double and triple click: select by words or lines
- handle shift click: extend selection
- add `EditState::mouse_down_offset` for initial dragging buffer offset
- pass `QEEvent *ev` to `mouse_goto()` handlers

events:
- add synthetic key events: QUIT CLOSE EXIT
- use synthetic events for GUI interaction (no longer simulate keystrokes)

tty:
- fix large OSC sequence support for terminal clipboard retrieval

Multicursor:
- use new `QECursor` for multicursor local states
- reallocate `multi_cursor` array in chunks

misc:
- add `eb_peekc(EditBuffer *b, int offset)`
- boolean cmdline options no longer require an argument, true if none provided
- int cmdline options either require an argument (CMD_LINE_INT_ARG) or take an
  optional argument, value is incremented if argument is not provided.
