It was accidentally broken in commit 0f4c439fc7, shipped since
8.8.0 (May 2024) and yet not a single person has noticed or reported,
indicating that we might as well drop support for FTP Kerberos.

Krb5 support was added in 54967d2a3a (July 2007), and we have
been carrying the extra license information around since then for this
code. This commit removes the last traces of that code and thus we can
remove the extra copyright notices along with it.

Closes #18577

NAME

CURLOPT_KRBLEVEL - FTP kerberos security level

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_KRBLEVEL, char *level);

DESCRIPTION

Deprecated. It serves no purpose anymore.

Pass a char pointer as parameter. Set the kerberos security level for FTP; this also enables kerberos awareness. This is a string that should match one of the following: clear, safe, confidential or private. If the string is set but does not match one of these, private is used. Set the string to NULL to disable kerberos support for FTP.

The application does not have to keep the string around after setting this option.

DEFAULT

NULL
