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.

Fixed bug #76717

Print INT_MIN as -INT_MAX-1 to avoid it getting parsed as a float
literal due to integer overflow.

N;.

Fix ref ID handling when serializing $GLOBALS

This was already broken previously, but in PHP 7.3 stricter
validation during unserialization made this into an error.

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.

Export stdClass objects using (object) cast (fixes #48016)

Before this change, var_export()'s output for stdClass objects calls
the non-existent stdClass::__set_state method, and is therefore useless.

This commit makes var_export() output an (object) cast from an array
instead, which when evaluated, will produce a stdClass object. Other
classes see unchanged output.

Allow internal functions to return values by reference (this was disabled in implementation of DO_ICALL, but enabled in DO_FCALL).
However, don't require internal functions returning by reference to return a reference.
Mark unserialize() as returning by reference and remove unwrap_reference hack, to allow proper returning of self referenced arrays using a reference.
Currently unserialize() is the only internal function that may return a reference.
