Replace krb5 1.21.3 with 1.22.2. The memory leak fixes previously applied via patch are included in 1.22 upstream. The NegoEx CVE fixes (CVE-2026-40355, CVE-2026-40356) patch still applies cleanly and is retained until they land upstream. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> (cherry picked from commit 5fffb24)
krb5 1.22.2 has a bug where struct kdclist and kdclist_entry are defined inside a KRB5_DNS_LOOKUP conditional, but the functions using them are outside it. When configure doesn't define KRB5_DNS_LOOKUP (as in the Bazel sandbox), the structs are incomplete at compile time. Cherry-pick the upstream fix from master (3c672ca). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> (cherry picked from commit ba231dd)
The backport bot cherry-picked the dev lockfile (lockFileVersion 26, Bazel 9.1.0) into this v26.1.x branch, which uses Bazel 8.4.1 (lockFileVersion 18). Rebase onto current v26.1.x also picks up the openssl 3.5.7 upgrade (commit 6911bfb). Regenerated with `bazel mod deps --lockfile_mode=update` to produce a valid lockFileVersion 18 lockfile reflecting both the openssl 3.5.7 and krb5 1.22.2 changes.

Upgrades krb5 from 1.21.3 to 1.22.2 on the v26.1.x branch to address CVE-2026-40355 and CVE-2026-40356 (NegoEx parsing vulnerabilities). The memory leak fixes previously applied via 0001 patch are included in 1.22.x upstream, so that patch is dropped. The NegoEx CVE patches still apply cleanly to 1.22.2 and are retained.
