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

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

  this allows more generic implemetation, without including qe.h
- rename fill_border() as fill_window_slack() for readability
- add QELEVEL environment variable to detect recursive invocation
- use stricter parser for load_ligatures()
- bump VERSION to 5.3.4u

98939ddcac changed API for completion functions:
- use CompleteState struct
- use complete_test for each potential match with simple prefix comparison

  lexicographical order but sort numeric portions in numerical order
use qe_collate in popup lists and dired

  stuff is bogus and should be rewritten

5768f42cd8 no longer use ctype.h macros and functions
