SECURITY UPDATE: libcurl may reuse the wrong connection for SMB(S)
transfers, leading to access of an unintended SMB share with the
same credentials.
debian/patches/CVE-2026-5773.patch: disable connection reuse for
SMB(S) in lib/url.c by returning early from ConnectionExists() when
the requested protocol is SMB or SMBS.
CVE-2026-5773
test46-bump-cookie-expiry.patch: bump the hard-coded cookie expiry
timestamp in tests/data/test46 from 2025-02-10 to 2099-01-01 so the
cookie-jar test no longer fails on systems whose wall clock has
advanced past February 2025.
