Fixed bug #81015

Make sure that the previous opline is part of the same block,
otherwise it may be non-dominating.

The test case does not fail on PHP-7.4, but I think the general
problem can appear on 7.4 as well, so I'm applying the patch to
that branch.

Fixed bug #81007

Backport a change from the master branch. We usually test 32-bit
using -m32 from an x86-64 host, probably nobody tried using an
actual 32-bit host.

Fix #79100: Wrong FTP error messages

First we need to properly clear the `inbuf`, what is an amendment to
commit d2881adcbc[1].

Then we need to report `php_pollfd_for_ms()` failures right away; just
setting `errno` does not really help, since at least in some cases it
would have been overwritten before we actually could check it. We use
`php_socket_strerror()` to get a proper error message, and define
`ETIMEDOUT` to the proper value on Windows; otherwise we catch the
definition in errno.h, which is not compatible with WinSock. The
proper solution for this issue would likely be to include something
like ext/sockets/windows_common.h.

Finally, we ensure that we only report warnings using `inbuf`, if it is
not empty.

Fix #80460: ODBC doesn't account for SQL_NO_TOTAL indicator

The `StrLen_or_IndPtr` parameter usually may be `SQL_NO_TOTAL`; we need
to cater to that possibility to avoid working with negative string
lengths and other issues. A noteable exemption are calls to
`SQLGetData()` which return `SQL_SUCCESS`; in that case `SQL_NO_TOTAL`
can not occur.

Closes GH-6809.
