E.g. `build/gen_stub.php *.stub.php` will generate `*_arginfo.h`
from multiple files.
Previously, gen_stub.php would silently ignore files after the first file.
Invoking gen_stub.php with no arguments will continue to process the entire
directory.
The way to fix it is to disable certain match start optimizaions. The
observed performance impact appears negligible ATM, compared to the
functional regression revealed.
A possible side effect might occur if a pattern uses (*COMMIT) or
(*MARK), which is however not a very broadly used syntax in PHP. Still
this should be observed and handled by possibly adding a possibility to
reverse PCRE2_NO_START_OPTIMIZE on the user side.
One test shows a behavior change, where instead of int 0 the match
would produce an error and return false. Except strict comparison
is used, this should be acceptable.

Removes unnecessary copying of fiber return value to transfer value. This zval was not used as the return of start/resume/throw, instead being destroyed when the fiber was dead. Now the zval initialized to NULL when starting the fiber is maintained as the transfer value and is subsequently returned from start/resume/throw.
Add zend_fiber prefix to delegate_transfer_result().
Ensure status is set to INIT when initializing the fiber context in case memory is not zeroed.
Assert destination fiber context is not dead.
Update stack alloc failure messages.
getThis() -> ZEND_THIS
* Move spl_offset_convert_to_long() to spl_fixedarray.c
It is only used there, which explains its weird offset semantics
* Refactor SplFixedArray offset handling
- Implement warning for resource type
- Throw a proper TypeError instead of a RuntimeException
* Use a proper Error to signal that [] cannot be used with SplFixedArray
* Refactor SplFixedArray has_dimension helper
* Drop some ZPP tests
Rather than using def_info, check against the actual arg_info type.
As it is stored as a type mask nowadays, this is not much harder,
but more general and more robust as we don't need to deal with
inaccurate cases.
This code is repeated a few time. Two occurrences additionally
contained checks for user classes in CG(class_table) with the
same file name, but as far as I know these should always be in
the script class_table, so I'm omitting the check here.
That happens on Travis s390x for whatever reasons. Thus, instead of
checking for `fallocate -h`, we attempt the real allocation and skip if
that fails.
When mapping the file, we need to pass the proper `dwFileOffsetHigh`
instead of `0`.

Closes GH-7158.
Previously, mbstring would accept a lot of things which were not valid
UHC text. No more.
- Don't allow single-byte control characters to appear where the 2nd
byte of a multi-byte character should be.
- Validate that the 2nd byte of a multi-byte character is in the
expected range.
- Treat it as an error if a multi-byte character is truncated.
Also add a test suite to confirm that UHC conversion (both to and from
Unicode) works according to spec.
