This closes the last hole in the supported types for internal
function arginfo types. It's now possible to represent unions of
multiple classes. This is done by storing them as TypeA|TypeB and
PHP will then convert this into an appropriate union type list.
Closes GH-6581.
JIT ignores that the `zend_write` callback is overwritten, so we define
our own callback and caller.
We also fix the "inconsistent DLL binding" warnings on Windows, by
introducing `PHP_ZEND_TEST_API`.
Closes GH-6391.
We have to error on unhandled exceptions in FFI callbacks, to avoid
passing back undefined values.
This has been discussed and agreed upon in a previous PR[1].

Closes GH-6366.
From an engine perspective, named parameters mainly add three
concepts:
* The SEND_* opcodes now accept a CONST op2, which is the
argument name. For now, it is looked up by linear scan and
runtime cached.
* This may leave UNDEF arguments on the stack. To avoid having
to deal with them in other places, a CHECK_UNDEF_ARGS opcode
is used to either replace them with defaults, or error.
* For variadic functions, EX(extra_named_params) are collected
and need to be freed based on ZEND_CALL_HAS_EXTRA_NAMED_PARAMS.

Closes GH-5357.
Casting objects to bool is supposed to yield `true`. Since the
`cast_object` handler is required now, we have to implement the
`_IS_BOOL` conversion there.
The hash is used to check whether the arginfo file needs to be
regenerated. PHP-Parser will only be downloaded if this is actually
necessary.
This ensures that release artifacts will never try to regenerate
stubs and thus fetch PHP-Parser, as long as you do not modify any
files.
Closes GH-5739.
Add ZVAL_CHAR/RETVAL_CHAR/RETURN_CHAR as a shortcut for using
ZVAL_INTERNED_STRING and ZSTR_CHAR.
Add zend_string_init_fast() as a helper for the empty string /
one char interned string / zend_string_init() pattern.
Also add corresponding ZVAL_STRINGL_FAST etc macros.
Closes GH-5684.
--file-cache-prime populates the file cache,
--file-cache-use uses the file cache.
And fix a number of tests to run under file cache or disabled
timestamp validation.
We must not attempt to access arbitrary union members when retrieving
debug info, because that may not be valid. Therefore we do no longer
dereference pointer types inside of unions, but report their address as
string in `%p` format instead.
We have to actually determine the proper `SIZEOF_OFF_T`.
Interestingly, it is `4` on Windows x64.
We also have to prevent the redefinition in pg_config.h. The clean
solution would likely be to not include pg_config.h at all, but that's
out of scope for BC reasons for now.
