Fix #77359: spl_autoload causes segfault

Use the correct function to free the string.

Remove unused Git attributes ident

Remove unused Git attributes ident

The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.

In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.

This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.

Reduce spl_autoload() overhead

Use zend_string_release_ex() instread of zend_string_release() in places, where we sure about string persistence.

Implement spl_object_id(object $x) : int

spl_object_id is a new function returning the object handle,
as a signed integer.

Discussion for this new function is ongoing on php-int

Implement spl_object_id(object $x) : int

spl_object_id is a new function returning the object handle,
as a signed integer.

Discussion for this new function is ongoing on php-internals, see
https://marc.info/?t=143835274500003&r=1&w=2

The object id is unique for the lifetime of the object.
When the object is garbage collected,
different objects may & will have the same object id.

- This is also the case for the string generated by spl_object_hash

It is always possible to cast the object handle to a **signed** zend_long
in php 7.2. _zend_object->handle is always of the type `uint32_t`.
(zend_long is 32 bits on 32 bit builds, 64 bits on 64 bit builds)

As of php 7.0, the object id uniquely identifies the object,
there can't be two objects with the same id but different handlers
(See the implementation of spl_object_hash)

Skip the pointless XORing, as discussed in internals.

- It was intended to avoid exposing in-memory addresses.
- The object handle is not a memory address.
- The output of var_dump() includes the object handle(id)
