Use memrchr() when available

On x86_64 glibc memrchr() uses SSE/AVX CPU extensions and works much
faster then naive loop. On x86 32-bit we still use inlined version.

memrchr() is a GNU extension. Its prototype becomes available when
<string.h> is included with defined _GNU_SOURCE macro. Previously, we
defined it in "php_config.h", but some sources may include <string.h>
befire it. To avod mess we also pass -D_GNU_SOURCE to C compiler.

Drop support for printf p modifier

To be conservative, cause a fatal error if the p modifier is
encountered, in case this is still used by some extension.

Avoid make_printable_zval() in other printf implementations as well

This is the same as the previous commit, for copies of that code.

Remove mention of PHP major version in Copyright headers

Remove checks for locale.h, setlocale, localeconv

The `<loccale.h>` header file, setlocale, and localeconv are part of the
standard C89 [1] and on current systems can be used unconditionally.

Since PHP 7.4 requires at least C89 or greater, the `HAVE_LOCALE_H`,
`HAVE_SETLOCALE`, and `HAVE_LOCALECONV` symbols defined by Autoconf in
configure.ac [2] can be ommitted and simplifed.

The bundled libmagic (file) has also been patched already in version
5.35 and up in upstream location so when it will be patched also in
php-src the check for locale.h header is still left in the configure.ac
and in windows headers definition file.

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.
