Back up fake_scope in zend_call_function

We regularly find new places where we forgot to reset fake_scope.
Instead of having to handle this for each caller of zend_call_function()
and similar APIs, handle it directly in zend_call_function().

Add zend_call_known_function() API family

Add zend_call_known_function() API family

This adds the following APIs:

void zend_call_known_function(
zend_function *fn, zend_object *object, zend_class_entry *called_scope,
zval *retval_ptr, int param_count, zval *params);

void zend_call_known_instance_method(
zend_function *fn, zend_object *object, zval *retval_ptr, int param_count, zval *params);
void zend_call_known_instance_method_with_0_params(
zend_function *fn, zend_object *object, zval *retval_ptr);
void zend_call_known_instance_method_with_1_params(
zend_function *fn, zend_object *object, zval *retval_ptr, zval *param);
void zend_call_known_instance_method_with_2_params(
zend_function *fn, zend_object *object, zval *retval_ptr, zval *param1, zval *param2);

These are used to perform a call if you already have the
zend_function you want to call. zend_call_known_function()
is the base API, the rest are just really thin wrappers around
it for the common case of instance method calls.

Closes GH-5692.

Fix bug #78226: Don't call __set() on uninitialized typed properties

Assigning to an uninitialized typed property will no longer trigger
a call to __set(). However, calls to __set() are still triggered if
the property is explicitly unset().

This gives us both the behavior people generally expect, and still
allows ORMs to do lazy initialization by unsetting properties.

For PHP 8, we should fine a way to forbid unsetting of declared
properties entirely, and provide a different way to achieve lazy
initialization.

Remove local variables

This patch removes the so called local variables defined per
file basis for certain editors to properly show tab width, and
similar settings. These are mainly used by Vim and Emacs editors
yet with recent changes the once working definitions don't work
anymore in Vim without custom plugins or additional configuration.
Neither are these settings synced across the PHP code base.

A simpler and better approach is EditorConfig and fixing code
using some code style fixing tools in the future instead.

This patch also removes the so called modelines for Vim. Modelines
allow Vim editor specifically to set some editor configuration such as
syntax highlighting, indentation style and tab width to be set in the
first line or the last 5 lines per file basis. Since the php test
files have syntax highlighting already set in most editors properly and
EditorConfig takes care of the indentation settings, this patch removes
these as well for the Vim 6.0 and newer versions.

With the removal of local variables for certain editors such as
Emacs and Vim, the footer is also probably not needed anymore when
creating extensions using ext_skel.php script.

Additionally, Vim modelines for setting php syntax and some editor
settings has been removed from some *.phpt files. All these are
mostly not relevant for phpt files neither work properly in the
middle of the file.

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.
