Fix GH-9348: FTP & SSL session reuse

The issue referenced here doesn't contain a reproducer, but I recently
received an email of a user with the exact same problem. I was able to
recreate the scenario locally using vsftpd and setting
`require_ssl_reuse=YES` in the vsftpd configuration.

It turns out that our session resumption code is broken. It only works a
single time: the first time a data connection opens. Subsequent data
connections fail to reuse the session. This is because on every data
connection a new session is negotiated, but the current code always
tries to reuse the (stale) session of the control connection.

To fix this, we use SSL_CTX_sess_set_new_cb() to setup a callback that
gets called every time a new session is negotiated. We take a strong
reference using SSL_get1_session() and store it in the ftpbuf_t struct.
Every time we open a data connection we'll take that session.
This works because every control connection has at most a single
associated data connection.

Also disable internal session caching storage to not fill the cache up
with useless sessions.

There is no phpt for this because PHP does not support enforcing SSL
session reuse.
It is however testable manually by setting up vsftpd and setting the
`require_ssl_reuse=YES` function from before.

Closes GH-12851.

Fix GH-10562: Memory leak and invalid state with consecutive ftp_nb_fget

When the user does not fully consume the data stream, but instead opens
a new one, a memory leak occurs. Moreover, the state is invalid: when
more commands arrive they'll be handled out-of-sync because the state of
the client does not match what the server is doing.
This leads to all sorts of weirdness, for example:
Warning: ftp_nb_fget(): OK.

Fix it by gracefully closing the old data stream when a new data stream
is started.

Fix GH-10521: ftp_get/ftp_nb_get resumepos offset is maximum 10GB

The char arrays were too small for a long on 64-bit systems, which
resulted in cutting off the string at the end with a NUL byte. Use a
size of MAX_LENGTH_OF_LONG to fix this issue instead of a fixed size
of 11 chars.

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.
