f547412cba Fix #79177: FFI doesn't handle well PHP exceptions within callback 
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].

[1] <https://github.com/php/php-src/pull/5120>

Closes GH-6366.

d5300873c5 Fix #79571: FFI: var_dumping unions may segfault 
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.

05f3cd23ed Fix #79096: FFI Struct Segfault 
We must not assume that the size of a function's return value is at
most `sizeof(ffi_arg)`, but rather have to use the size which already
has been determined for the return type if it is larger than
`sizeof(ffi_arg)`.

To be able to have a regression test, we export the required test
function from the zend-test extension, and make sure that the test
can be run on different platforms regardless of whether zend-tests was
built statically or dynamically.

bedbecf56d Implement #78270: Support __vectorcall convention with FFI 
To work around the limitation of the current rudimentary vectorcall
support in our patched libffi, we forbid yet unsupported declarations,
i.e. float/double parameters at certain positions (SIMD vector types
and HVA types are not supported anyway).

1ed9ebdea5 Support calling convention specific function name mangling 
On Windows certain calling conventions cause C function names to be
mangled, so to import them we have to use the properly mangled names.

6738241aec Avoid usage of internal get/set object handlers. They are going to be removed in PHP-8. 
Scalar FFI values now should be accessed through special "cdata" property.

    $x = FFI::new("int");
    $x = 42;

    should be changed into

    $x = FFI::new("int");
    $x->cdata = 42;
