Preferably include from build dir (#13516)

* Include from build dir first

This fixes out of tree builds by ensuring that configure artifacts are included
from the build dir.

Before, out of tree builds would preferably include files from the src dir, as
the include path was defined as follows (ignoring includes from ext/ and sapi/) :

-I$(top_builddir)/main
-I$(top_srcdir)
-I$(top_builddir)/TSRM
-I$(top_builddir)/Zend
-I$(top_srcdir)/main
-I$(top_srcdir)/Zend
-I$(top_srcdir)/TSRM
-I$(top_builddir)/

As a result, an out of tree build would include configure artifacts such as
`main/php_config.h` from the src dir.

After this change, the include path is defined as follows:

-I$(top_builddir)/main
-I$(top_builddir)
-I$(top_srcdir)/main
-I$(top_srcdir)
-I$(top_builddir)/TSRM
-I$(top_builddir)/Zend
-I$(top_srcdir)/Zend
-I$(top_srcdir)/TSRM

* Fix extension include path for out of tree builds

* Include config.h with the brackets form

`#include "config.h"` searches in the directory containing the including-file
before any other include path. This can include the wrong config.h when building
out of tree and a config.h exists in the source tree.

Using `#include <config.h>` uses exclusively the include path, and gives
priority to the build dir.

Fix GH-13860: Incorrect PHP_STREAM_OPTION_CHECK_LIVENESS case in ext/openssl/xp_ssl.c - causing use of dead socket

php_socket_errno() may return a stale value when recv returns a
value >= 0. As such, the liveness check is wrong.
This is the same bug as #70198 (fixed in GH-1456). So we fix it in the
same way.

ext/openssl: Bump minimum required OpenSSL version to 1.1.1

Bumps the minimum required OpenSSL version from 1.0.2 to 1.1.1.

OpenSSL 1.1.1 is an LTS release, but has reached[^1] EOL from upstream. However, Linux distro/OS vendors
continue to ship OpenSSL 1.1.1, so 1.1.1 was picked as the minimum. The current minimum 1.0.2 reached
EOL in 2018.

Bumping the minimum required OpenSSL version makes it possible for ext-openssl to remove a bunch of
conditional code, and assume that TLS 1.3 (shipped with OpenSSL 1.1.1) will be supported everywhere.

- Debian buster: 1.1.1[^2]
- Ubuntu 20.04: 1.1.1[^3]
- CentOS/RHEL 7: 1.0.2
- RHEL 8/Rocky 8/EL 8: 1.1.1
- Fedora 38: 3.0.9 (`openssl11` provides OpenSSL 1.1 as well)

RHEL/CentOS 7 reaches EOL mid 2024, so for PHP 8.4 scheduled towards the end of this year, we can safely
bump the minimum OpenSSL version.

streams/xp_socket: eliminate poll() when MSG_DONTWAIT is available

If there is a zero timeout and MSG_DONTWAIT is available (or the
socket is non-blocking), the poll() call is not necessary, and we can
just call recv() right away.

Before this change:

poll([{fd=4, events=POLLIN|POLLPRI|POLLERR|POLLHUP}], 1, 0) = 0 (Timeout)
poll([{fd=4, events=POLLIN|POLLERR|POLLHUP}], 1, 60000) = 1 ([{fd=4, revents=POLLIN}])
recvfrom(4, "HTTP/1.1 301 Moved Permanently\r\n"..., 8192, MSG_DONTWAIT, NULL, NULL) = 348
poll([{fd=4, events=POLLIN|POLLPRI|POLLERR|POLLHUP}], 1, 0) = 1 ([{fd=4, revents=POLLIN}])
recvfrom(4, "", 1, MSG_PEEK, NULL, NULL) = 0

After this change:

recvfrom(4, 0x7ffe0cc719a0, 1, MSG_PEEK|MSG_DONTWAIT, NULL, NULL) = -1 EAGAIN (Resource temporarily unavailable)
poll([{fd=4, events=POLLIN|POLLERR|POLLHUP}], 1, 60000) = 1 ([{fd=4, revents=POLLIN}])

recvfrom(4, "", 1, MSG_PEEK|MSG_DONTWAIT, NULL, NULL) = 0

The first poll() is replaced by recvfrom(), and the third poll() is
omitted completely.

Fix bug #79589: ssl3_read_n:unexpected eof while reading

The unexpected EOF failure was introduced in OpenSSL 3.0 to prevent
truncation attack. However there are many non complaint servers and
it is causing break for many users including potential majority
of those where the truncation attack is not applicable. For that reason
we try to keep behavior consitent with older OpenSSL versions which is
also the path chosen by some other languages and web servers.
