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 ZEND_OBJECTS_STORE_HANDLERS macro

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.

Fixed bug #76427 (Segfault in zend_objects_store_put)

Export standard object handlers, to avoid indirect access

Keep initialized object_handlers structures in read-only memory.

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)

Add zend_object_alloc() API

Using ecalloc() to create objects is expensive, because the
dynamic-size memset() is unreasonably slow. Make sure we only
zero the main object structure with known size, as the properties
are intialized separately anyway.

Technically we do not need to zero the embedded zend_object
structure either, but as long as the memset argument is constant,
a couple more bytes don't really matter.

Bug Fix:
Corrupted class entries on shutdown when a destructor spawns another object
(C) 2017 CommerceByte Consulting

When zend_objects_store_call_destructors() is called from the shutdown sequence -
it's calling the dtor's for remaining objects one by one in sequence of object handles.
If the dtor spawns one or more objects, and the new objects happen to reuse the old handles -
their dtor's are not called in this cycle.
The dtor's are called later on, when zend_deactivete() kicks in, and the static property lists in the class entries are freed.
This causes "Undefined static property" errors, and/or SIGSEGV.

Solution:
zend_object_store.no_reuse field is added
Set to 0 on initialization, set to 1 on the shutdown sequence.
zend_objects_store_put(zend_object *) checks the no_reuse flag, and never reuses the old handle slots if set.
This way, the dtor's for newly spawned objects are guaranteed to be called in the zend_objects_store_call_destructors() loop.
