- Fix CVE-2025-26465 and minor bugs found by Qualys and Rocky Linux while
  searching the source code for similar error patterns

- Rebase on 8.7p1-43

- Patch the code to silently ignore GSSAPIKeyExchange when unsupported

- Rebase on 8.7p1-38.4

- Fix CVE-2024-6409

- Rebase on 8.7p1-38.1

- Fix CVE-2024-6387 regreSSHion

- Rebase on 8.7p1-38

- Comment out GSSAPI* lines in /etc/ssh/ssh*_config.d/50-redhat.conf and patch
  the code to silently ignore GSSAPIKexAlgorithms when unsupported (like it is
  in our new without-Kerberos build)

- Rebase 8.7p1-34.el9_3.security.0.1 on 8.7p1-34.3
- Build without Kerberos support (shortens "ldd sshd" from 20 to 13 lines)

- Rebase 8.7p1-30.el9.security.0.2 on 8.7p1-34

- Load libsystemd.so.0, not libsystemd.so, as the latter is only provided by
  systemd-devel

- Instead of linking against libsystemd, load it dynamically in a temporary
  child process to avoid polluting actual sshd's address space with that
  library and its many dependencies (shortens "ldd sshd" from 28 to 20 lines)
