Fix bug #69751

Change error message of sprintf/printf for missing/invalid position
specifier to make it clear that this is talking about the specifier,
not the number of arguments passed to the function. Also mention
the upper limit of INT_MAX.

Add support for * width and precision in printf()

If * is used for width/precision in printf, then the width/precision
is provided by a printf argument instead of being part of the format
string. Semantics generally match those of printf in C.

This can be used to easily reproduce PHP's float printing behavior:

// Locale-sensitive using precision ini setting.
// Used prior to PHP 8.0.
sprintf("%.*G", (int) ini_get('precision'), $float);

// Locale-insensitive using precision ini setting.
// Used since to PHP 8.0.
sprintf("%.*H", (int) ini_get('precision'), $float);

// Locale-insensitive using serialize_precision ini setting.
// Used in serialize(), json_encode() etc.
sprintf("%.*H", (int) ini_get('serialize_precision'), $float);

Closes GH-5432.

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.
