Subject: [PATCH] libssh: when keyboard-interactive auth fails, try password
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The state machine had a mistake in that it would not carry on to that
next step.
This also adds a verbose output what methods that are available from the
server and renames the macros that change to the next auth methods to
try.

Fixes #11196
Closes #11197

Subject: [PATCH] socks: return error if hostname too long for remote resolve
Prior to this change the state machine attempted to change the remote
resolve to a local resolve if the hostname was longer than 255
characters. Unfortunately that did not work as intended and caused a
security issue.
Name resolvers cannot resolve hostnames longer than 255 characters.
Bug: https://curl.se/docs/CVE-2023-38545.html
