from a minimized locale, addLikelySubtags augments it with likely
subtags so no changes is the locale is already maximized e.g.
`en_Latn_US`, minimizeSubtags on the other hand does the opposite
operation.
Checks is the locale is written left to right.
It makes sure all the needed likely subtags are included (maximization)
then determines the direction by known matches.

This requirements bump should rarely affect anybody in practice. All
major distros already ship more recent ICU versions, and even for
Solaris 11, ICU 57.1 is available via OpenCSW. Note that ICU 57.1 has
been released on 2016-03-23[1].

Closes GH-16688.
To match other capitalized strings like `ZEND_STR_UNKNOWN_CAPITALIZED` and
`ZEND_STR_ARRAY_CAPITALIZED`. Since this known string was only added in PHP
8.4, no backwards compatibility alias is needed.
When functions' or class methods' availability is based on some preprocessor
condition, the generated arginfo header files wrap the declarations in the
preprocessor `#if` conditional blocks, one per declaration, even if they are in
the same conditional block based on comments in the stub file. Instead of
having multiple conditional blocks one after the other with the same condition,
combine them into a single conditional block.
When a class (or enum) has no methods, rather than using an array that only
contains `ZEND_FE_END`, use `NULL` for the functions. The implementation of
class registration for internal classes, `do_register_internal_class()` in
zend_API.c, already skips classes where the functions are `NULL`. By removing
these unneeded arrays, we can reduce the size of the header files, while also
removing an unneeded call to zend_register_functions() for each internal class
with no extra methods.
Currently, internal classes are registered with the following code:
INIT_CLASS_ENTRY(ce, "InternalClass", class_InternalClass_methods);
class_entry = zend_register_internal_class_ex(&ce, NULL);
class_entry->ce_flags |= ...;
This has worked well so far, except if InternalClass is readonly. It is because some inheritance checks are run by zend_register_internal_class_ex before ZEND_ACC_READONLY_CLASS is added to ce_flags.
The issue is fixed by adding a zend_register_internal_class_with_flags() zend API function that stubs can use from now on. This function makes sure to add the flags before running any checks. Since the new API is not available in lower PHP versions, gen_stub.php has to keep support for the existing API for PHP 8.3 and below.
I noticed that PHP does not have a grapheme cluster based str_split function.
So I created the grapheme_str_split function.
This feature will allow you to correctly handle emoji
and variable selectors.

Default them to IntlDateFormatter:FULL, which has value 0, which
was what you would get if you passed null to these arguments in
weak typing mode. The documentation called this ICU's default
date/time type.
In preparation for generating method signatures for the manual.
This change gets rid of bogus false|null return types, a few unnecessary trailing backslashes, and settles on using ? when possible for nullable types.
