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.

API cleanup.
Removed useless filename and lineno arguments, used in DEBUG build.
The patch doesn't break source compatibility of public API (only binary compatibility).

Fixed reference-counting in zend_parse_arg_str_weak()

zval_dtor() doesn't make a lot of sense in PHP-7.* and it's used incorrectly in some places.

Add zend_update_static_property_ex API

And cleanup the implementation to perform a normal by-value
assignment.

Add zend_read_static_property_ex API

For symmetry with zend_read_property_ex.

Removed INIT_OVERLOADED_CLASS... macros

Fixed ZTS race condition (zend_class_entry->ce_flags of internal classes must not be modified, because internal class enties are shared between threads)

Lazy function copying from op_cache SHM into process memory

Micro-optimization

Fixed bug #76509

In PHP static properties are shared between inheriting classes,
unless they are explicitly overwritten. However, because this
functionality was implemented using reference, it was possible
to break the implementation by reassigning the static property
reference.

This is fixed by switching the implementation from using references
to using INDIRECTs, which cannot be affected by userland code.

Removed "dead" code (zend_hash_update() never fails)

Removed useless zval_ptr_dtor()

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

Fixed bug #76337

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

Use bool instead of boolean while throwing a type error

PHP requires boolean typehints to be written "bool" and disallows
"boolean" as an alias. This changes the error messages to match
the actual type name and avoids confusing messages like "must be
of type boolean, boolean given".

This a followup to ce1d69a1f6dcf15d43029301059c25e5bc09a577, which
implements the same change for integer->int.
