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()`

7e70e611b6 Use char32_t for all code point variables and arrays
- char32_t is defined in cutils.h but may conflict with <uchar.h>
- all qe_isxxx functions take a char32_t
- add etf8x encoding for full range of char32_t type
- add utf8_decode_strict()
- add ustr_match_keyword()
- utf8_encode() / utf8_decode() handle up to 32 bits
- improve detect_charset():
  - detect utf8 and utf8x
  - avoid failure on partial utf8 sequence at end of buffer
  - detect overlong utf8 sequences
- fix display bugs for code points beyond MAX_UNICODE_DISPLAY
- simplify do_compare_windows(), avoid magic char values.
- rename functions:
    eb_encode_uchar -> eb_encode_char32
    eb_insert_uchar -> eb_insert_char32
    eb_insert_uchars -> eb_insert_char32_n
    eb_match_uchar -> eb_match_char32
    eb_delete_uchar -> eb_delete_char32
    eb_replace_uchar -> eb_replace_char32
    utf8_to_unicode -> utf8_to_char32
- use char32_t for all variables and arrays holding code-points
- fix some language syntax parsers.
- fix detect_eol_type_32bit(), used uint16_t instead of uint32_t
- bump VERSION to 5.4.0

d1fb4dde64 Add macros for block comparison, copy and move
After spending a few hours debugging a stupid memcpy size error, I
decided to use a typed version of memcpy, memcmp and memmove wherever
the array type size is greater than 1.

- add blockcmp(p1, p2, n), blockcpy(p1, p2, n), blockmove(p1, p2, n)
  for operation on typed arrays
- add max_uint() and min_uint()
- bumped VERSION to 5.3.4w
