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.

Use better destructor (key may be only IS_STRING or IS_LONG).

se zval_ptr_dtor_str() instead of zend_string_release_ex(Z_STR(*), 0)

Fixed bug #74670

Validate that "C" serialization payload is followed by "}" prior to
calling the unserialize() handler. This mitigates issues caused by
unserialize() not correctly handling strings that are not NUL
terminated. Making sure that there is a "}" at the end avoids the
problem.

Fix #76300 - Dont attempt to change visibility of a parent private

Removed useless zval_ptr_dtor()

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

Avoid useless checks, using zend_string_efree(), in cases where the string is known to be a temporary allocated zend_string.

Fix #76300 - Dont attempt to change visibility of a parent private

Optimize zend_hash_real_init()

Use macros to update specific parts of GC_TYPE_INFO() (direct assignments to GC_TYPE(), GC_FLAGS() and GC_INFO() are prohibited)

Use OBJ_FLAGS() macro to access object flags (even if they are currently stored together with GC_FLAGS)

Access HashTable.u.flags through HT_FLAGS() macro.

Avoid visibility checks for classes without predefined properties

Try to intern unserualized string keys

Optimized parse_iv2()

Use per-request heap instead of system one

Avoid HashTable allocations for empty arrays (using zend_empty_array).

Fixed unzserialize(), to disable creation of unsupported data structures through manually crafted strings. (Dmitry)
