Be more precise about possible types for mysqli methods
mysqli has an uncommon approach to 64-bit compatibility:
it will convert numbers that can't be represented on 32-bit
platforms to a string.
This is documented at
https://www.php.net/manual/en/mysqli-stmt.affected-rows.php#refsect1-mysqli-stmt.affected-rows-returnvalues
So if there's a query to a remote mysqli server that affects
more than 2.2 billion rows, then the opcache inference might be
incorrect.
(It's possible to add a MAY_BE_STRING_ON_32_BIT_PLATFORM bitflag macro to
account for this, but I don't think there's a need or want to?)
On Mac thread_local and __thread are not ABI compatible, in addition, thread_local
comes with additional overhead, __thread seems to be the most suitable linkage to use
regardless of c++/c

Support full variance if autoloading is used
Keep track of delayed variance obligations and check them after
linking a class is otherwise finished. Obligations may either be
unresolved method compatibility (because the necessecary classes
aren't available yet) or open parent/interface dependencies. The
latter occur because we allow the use of not fully linked classes
as parents/interfaces now.
An important aspect of the implementation is we do not require
classes involved in variance checks to be fully linked in order for
the class to be fully linked. Because the involved types do have to
exist in the class table (as partially linked classes) and we do
check these for correct variance, we have the guarantee that either
those classes will successfully link lateron or generate an error,
but there is no way to actually use them until that point and as
such no possibility of violating the variance contract. This is
important because it ensures that a class declaration always either
errors or will produce an immediately usable class afterwards --
there are no cases where the finalization of the class declaration
has to be delayed until a later time, as earlier variants of this
patch did.
Because variance checks deal with classes in various stages of
linking, we need to use a special instanceof implementation that
supports this, and also introduce finer-grained flags that tell us
which parts have been linked already and which haven't.
Class autoloading for variance checks is delayed into a separate
stage after the class is otherwise linked and before delayed
variance obligations are processed. This separation is needed to
handle cases like A extends B extends C, where B is the autoload
root, but C is required to check variance. This could end up
loading C while the class structure of B is in an inconsistent
state.

Fix a typo in opcache func info for "get_parrent_class"
This should only have one r.
http://php.net/get_parent_class mentions that it returns string|false
Also, I'm not 100% sure if this is right - should this include
MAY_BE_NULL to handle the case of too many parameters?
(then again, get_called_class() also returns null in the global scope)
```
php > var_export(get_parent_class(2,3));
Warning: get_parent_class() expects at most 1 parameter, 2 given in php
shell code on line 1

On some recent Windows systems, ext\pcre\tests\locales.phpt fails,
because 'pt_PT' is accepted by `setlocale()`, but not properly
supported by the ctype functions, which are used internally by PCRE2 to
build the localized character tables.
Since there appears to be no way to properly check whether a given
locale is fully supported, but we want to minimize BC impact, we filter
out typical Unix locale names, except for a few cases which have
already been properly supported on Windows. This way code like
It should be noted that the locale names causing trouble are not (yet)
documented as valid names anyway, see

Extend wildcard files section in EditorConfig [ci skip]
Changes:
- Trim trailing whitespace for all files except patches. There isn't
really any practical reason to not trim the trailing whitespace in all
other files. Binary files or phpt files that include trailing
whitespace as part of the test should be manually set in editors/IDEs
or by disabling the editorconfig for particular editing.
- Add *.ac, *.d, *.l, *.skl, *.re, *.wsdl, *.dtd, *.html, *.rng, *.xml,
*.xsd, *.xsl, buildconf, and Makefile* files settings.
Fix bug #78094: File Search Problem Excessive Time
Instead of checking GetBinaryType() for each file, we do a much cheaper
pre-check whether the filename extension matches .exe or .com, and call
GetBinaryType() only in this case. For BC we also report .bat and .cmd
files as executables again.
