Subject: [PATCH] Fix GH-10692: PHP crashes on Windows when an inexistent
 filename is executed

Fixes GH-10692

php_fopen_primary_script() does not initialize all fields of
zend_file_handle. So when it fails and when fastcgi is true, the
zend_destroy_file_handle() function will try to free uninitialized
pointers, causing a segmentation fault. Fix it by zero-initializing file
handles just like the zend_stream_init_fp() counterpart does.
