random extension macOs handling update.

Not such as fix but taking more precautions.
Indeed, the arc4random has two little flaws in this platform,
one already caught upfront by the extension (ie size 0), also
internal use of ccrng_generate which can silently fail in few rare
cases.

Closes #7824.

This subtraction may overflow the signed domain, which is UB. Use
an unsigned subtraction instead.

Make zpp failures always throw, independent of strict_types

Previously zend_parse_parameters (and FastZPP) would handle invalid
arguments depending on strict_types: With strict_types=1, a TypeError
is thrown, with strict_types=0 a warning is thrown and (usually) NULL
is returned. Additionally, some functions (constructors always and
other methods sometimes) opt-it to throwing regardless of strict_types.

This commit changes zpp to always generate a TypeError exception in
PHP 8.

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.
