Fix GH-12190: stream_context_create with address and port at 0.

Prior to the 8.1 rewrite, inet_aton was used for ipv4 addresses
therefore addresses like `0` passed.
For the bindto's case where both ip and port are set as such, we discard
the address binding.

Fix #80067: Omitting the port in bindto setting errors

A recent commit[1] which fixed a memory leak introduced a regression
regarding the formerly liberal handling of IP addresses to bind to. We
fix this by reverting that commit, and fix the memory leak where it
actually occurs. In other words, this fix is less intrusive than the
former fix.

Fix #78210: Invalid pointer address

This is actually about three distinct issues:

* If an empty string is passed as $address to `stream_socket_sendto()`,
the `sa` is not initialized, so we must not pass it as `addr` to
`php_stream_xport_sendto()`.

* On POSIX, `recvfrom()` truncates messages which are too long to fit
into the specified buffer (unless `MSG_PEEK` is given), discards the
excessive bytes, and returns the buffer length. On Windows, the same
happens, but `recvfrom()` returns `SOCKET_ERROR` with the error code
`WSAEMSGSIZE`. We have to catch this for best POSIX compatibility.

* In `php_network_parse_network_address_with_port()`, we have to zero
`in6` (not only its alias `sa`) to properly support IPv6.

Clarify usage of max_fd in php_poll2() on Windows

Actually, `max_fd` is not used on Windows, since `PHP_SAFE_MAX_FD` and
`select` ignore it; so it makes no sense to calculate it in the loop.
Even worse, since `php_socket_t` is unsigned on Windows, it will never
be modified during the loop, because `SOCK_ERR` is already the largest
representable value of that type.

Therefore we skip the loop on Windows, and add a clarifying comment.
