Fix #80849: HTTP Status header truncation

While truncating the contents of a header is okay, we must never omit
the trailing CRLF.

Closes GH-7238.

Better leak fix for cgi -s / -w

We also need to go through request shutdown. The naming is a bit

if not using fastcgi

Fix #79489: .user.ini does not inherit

On Windows, PATH_TRANSLATED may contain backslashes as well as slashes,
so we must not only check for `DEFAULT_SLASH`.

The `start` parameter of `php_cgi_ini_activate_user_config` is supposed

Fix #79491: Search for .user.ini extends up to root dir

The `start` parameter of `php_cgi_ini_activate_user_config` is supposed
to hold the byte offset of the doc root in the given `path`. However,
the current expression which fixes a potential type incompatibility
will ever only evaluate to zero or one, because it uses the *logical*
and operator (`&&`). Furthermore we notice that subtracting one from
`doc_root_len` is not necessary, so there is even no need for the
`start` parameter at all.

Move shebang handling into the lexer

Instead of handling shebang lines by adjusting the file pointer in
individual SAPIs, move the handling into the lexer, where this is
both a lot simpler and more robust. Whether the shebang should be
skipped is controlled by CG(skip_shebang) -- we might want to do
that in more cases.

This fixed bugs #60677 and #78066.

Remove checks for locale.h, setlocale, localeconv

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 HAVE_SIGNAL_H

The `<signal.h>` header file is part of the standard C89 headers [1] and
on current systems can be included unconditionally.

Since file requires at least C89 or greater, the `HAVE_SIGNAL_H` symbol
defined by Autoconf in Zend.m4 [2] can be ommitted and simplifed.

The bundled libmagic (file) also ommits the usage of HAVE_SIGNAL_H since
5.35 however current version in PHP is very modified 5.34 version and
will be refactored separately. Check for HAVE_SIGNAL_H is therefore
still done in the configure.ac.
