Fixed bug #79830 introduced by fixing bug #79821

This also fixes memory error in debug_zval_dump and var_export.

Fixed bug #79821

HashTable was reallocated (zend_hash_packed_grow) during php_var_dump, so we should call GC_ADDREF to make SEPARATE_ARRAY work.

Closes GH-5837.

Fix bug #79447

Partially reverts 846b6479537a112d1ded725e6484e46462048b35: instead of
throwing, this skips uninitialized typed properties when serializing objects.

This makes serialize with __sleep() behave the same as serialize()
without __sleep().

As in the non-__sleep() case, unserialize(serialize($x)) identity
may not be preserved due to replacement of uninitialized/unset
properties with default values. Fixing this will require changes to
the serialization format.

Closes GH-5396.

Throw Error when referencing uninit typed prop in __sleep

Previously this generated a notice, but would likely generate an
Error when unserializing.

Now we treat it with the same distinction as direct property
accesses, i.e. referencing an unset/undefined normal property
stays a notice, while a typed property becomes an Error exception.

This fixed bug #79002.

Closes GH-5050.

Populate hashtable of __sleep() properties

Instead of populating a hashtable of property names and then
directly serializing.

This has the advantage of a) detecting duplicate properties more
precisely and b) gives us the ability to discard values without
rewriting the serialization string after the fact for GH-5027.

Add max_depth option to unserialize()

Add a max_depth option to unserialize and an unserialize_max_depth
ini setting, which can be used to control the depth limit. The
default value is 4096.

This option is intended to prevent stack overflows during the
unserialization of deeply nested structures.

This fixes bug #78549 and addresses oss-fuzz #17581, #17589, #17664,
and #17788.

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.
