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`

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()`

- `check_window()`, `check_buffer()`, `qe_kill_buffer()`, `qe_get_history()`
- `qe_register_charset()`, `find_charset()`

Add error message handlers:
- add `QEDisplay::dpy_error()` method

216b3ff8b7 Fix gcc 12.2 insane optimisation issues fixes issue #11
* use memcpy and other value casts to avoid strict aliasing violations.
  gcc 12.2 was wrongly assuming that utf8_decode(&p) did not modify p
  because *pp was never explicitly set, albeit *(const u8 **)pp = p; was
  storing te updated value of p into it and the code generated for that
  was produced.  The code generator was miscompiling strtokey1 because
  the compiler relied on bogus code analysis at the call site.

  The gcc team is wasting many hours of valuable debugging time.
  They should at least issue a warning about aliasing rules violations.

* fix compiler warning on missing Xvideo header

* fix compiler warning on missing fallthrough

* bump version to 5.4.1c

4939f6e927 Fix overwrite mode issues
- rename s->insert as s->overwrite with opposite semantics
- fix overwrite mode behavior:
   TABs are filled, then removed
   TABs and newlines are always inserted
   backspace removes TABS and newlines
   backspace overwrite previous glyph with 1 or 2 spaces except at EOL
   backspace only replaces with spaces before a TAB to preserve layout
   quoted-insert always inserts
- quoted-insert inserts special key as escape sequences
- make KEY_UNKNOWN and KEY_NONE special keys matched by KEY_IS_SPECIAL()
- eb_replace() returns the number of bytes written
- add text_screen_width() to compute the actual screen column
- add convenient bindings for laptops with limited special keys:
  - overwrite-mode: C-c o
  - insert-mode: C-c i
  - toggle-read-only: C-c %
  - not-modified: C-c ~
- document set-visited-file-name
- remove filename if set-visited-file-name with an empty string
- simplify eb_insert_uchars()
- bumped version to 5.3.4e
