Destroy constant values before object store

Now that constants can contain objects (currently only enums),
we should destroy them before we free the object store, otherwise
there will be false positive leak reports.

This doesn't affect the fast_shutdown sequence.

Replace zend_bool uses with bool

We're starting to see a mix between uses of zend_bool and bool.
Replace all usages with the standard bool type everywhere.

This gives us better object leak diagnostics.

Check for NULL GC type in objects_store_del

This might happen if OBJ_RELEASE is used on an object that was already
released by GC. Specific cases of this issue were previously fixed in
ffaee27478a9cb338e40edeb5acf233f9cb67111 and
72104d2b6ecbbabd18de15f10739be5ce3dc9ce0, however the issue still
affects 3rd-party extensions using OBJ_RELEASE.

The whole GC type NULL + OBJ_IS_VALID + IS_FREE_CALLED system seems
overly complicated and can probably be simplified in 7.4.

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.

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)

Replace checks with asserts
