*equivalents* are strings that should compare equal in a `compare-windows`
session. You can define such strings in a **.qerc** file in the directory of
one of the files being compared. This helps ignoring known changes such as
type of function renaming... Here is an example to help compare files between
the `bellard/quickjs` and the `quickjs-ng/quickjs` repositories:
```
define_equivalent("JS_DupValue(ctx, ", "js_dup(");
define_equivalent("JSValue", "JSValueConst");
define_equivalent("JS_NewInt32(ctx, ", "js_int32(");
define_equivalent("JS_NewInt32(ctx,\n", "js_int32(");
define_equivalent("JS_NewUint32(ctx, ", "js_uint32(");
define_equivalent("JS_NewUint32(ctx,\n", "js_uint32(");
define_equivalent("JS_NewBool(ctx, ", "js_bool(");
define_equivalent("JS_NewFloat64(ctx, ", "js_float64(");
define_equivalent("JS_EXTERN ", "");
define_equivalent("JS_EXTERN JS", "JS");
define_equivalent("JS_EXTERN JS_", "JS_");
ignore_equivalent = 1;
```
Other changes were necessary for proper utf8 skipping:
- add `utf8_prefix_len(str1, str2)` to compute the length of a common initial
prefix not falling inside UTF-8 encoded codepoints.
- add `utf8_decode_prev` to get the previous codepoint
- add `eb_match_str_utf8_reverse`
* Bind `next-buffer` to `C-x C-right` and `previous-buffer` to `C-x left` just like GNU Emacs
* next-buffer & previous-buffer skip buffers with BF_SYSTEM flag.
* next-buffer & previous-buffer command is ignored from minibuffer and popups.
* fix compilation errors on linux
* support quote as digit separator in C/C++ modes
- this convention is horrible!
- why not use _ which is compatible with the ppnumber syntax?

result instead of showing as message

* fix kill-matching-lines definition
* fix utf8_to_char32 implementation inconsistency for empty destination
* fix buffering errors in eb_insert_utf8_buf() and eb_insert_char32_buf()
* bump version to 5.4.1e
* 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.
