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

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.

Closes GH-11606.

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

size of MAX_LENGTH_OF_LONG to fix this issue instead of a fixed size
of 11 chars.

Fix #79100: Wrong FTP error messages

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.

There is no need for a new test case, since filesize_large.phpt already

`pcntl_fork()` and therefore cannot be run on Windows.

Remove local variables

This patch removes the so called local variables defined per
file basis for certain editors to properly show tab width, and
similar settings. These are mainly used by Vim and Emacs editors
yet with recent changes the once working definitions don't work
anymore in Vim without custom plugins or additional configuration.
Neither are these settings synced across the PHP code base.

A simpler and better approach is EditorConfig and fixing code
using some code style fixing tools in the future instead.

This patch also removes the so called modelines for Vim. Modelines
allow Vim editor specifically to set some editor configuration such as
syntax highlighting, indentation style and tab width to be set in the
first line or the last 5 lines per file basis. Since the php test
files have syntax highlighting already set in most editors properly and
EditorConfig takes care of the indentation settings, this patch removes
these as well for the Vim 6.0 and newer versions.

With the removal of local variables for certain editors such as
Emacs and Vim, the footer is also probably not needed anymore when
creating extensions using ext_skel.php script.

Additionally, Vim modelines for setting php syntax and some editor
settings has been removed from some *.phpt files. All these are
mostly not relevant for phpt files neither work properly in the
middle of the file.
