[php-src] Issue #9945: shmop_open should throw ValueError for ids overflowing sizeof int

Issue: https://github.com/php/php-src/issues/9945 Author: TysonAndre ### Description The following code: ```php <?php // based on ext/shmop/tests/shmop_open_private.phpt $write = 'test'; $shm1 = shmop_open(0x2_0000_0001, 'c', 0777, 1024); shmop_write($shm1, $write, 0); $shm2 = shmop_open(0x1_0000_0001, 'c', 0777, 1024); $read = shmop_read($shm2, 0, 4); var_dump(is_string($read) && $read !== $write); ``` Resulted in this output: ``` bool(false) ``` But I expected this output instead: ``` bool(true) ``` (seen on 64-bit linux with sizeof(int) == 4, sizeof(zend_long) == 8) Not really something users are likely to do deliberately This also means that 0x1_0000_0000 is an alias for IPC_PRIVATE, which always creates a new memory segment. Noticed while looking into #9944 ### PHP Version Any ### Operating System _No response_
