Fix #81283: shmop can't read beyond 2147483647 bytes

`start`, `count` and `shmop->size` are `zend_long`, so we must not
restrict to `INT_MAX`.

Closes GH-7301.

Mark resource-like objects as non-comparable

As these hold on to some internal resource, there can't be two

Add the ZEND_ACC_NO_DYNAMIC_PROPERTIES flag to Shmop

Convert shmop resources to opaque objects

We make `shmop_close()` a NOP, and deprecate the function right away;
detaching from SHM now happens when the wrapper object is freed.

Make error messages more consistent by fixing capitalization

Closes GH-5066 As a first step, let's capitalize their initial letter when it is applicable.

Use RETURN_THROWS() after zend_fetch_resource*()

Use RETURN_THROWS() during ZPP in most of the extensions

Except for some bigger ones: reflection, sodium, spl

Fixed inconsistent naming for stub, return type for shmop_size

Added shmop arginfo stubs

Remove some misleading RETURN_FALSE

These functions throw, so they can't return false.

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.
