SECURITY UPDATE: fix authentication bypass in cupsd caused by
dispatching on the client-supplied Authorization scheme without
checking it against the configured AuthType.
debian/patches/CVE-2025-58060.patch: reject "Authorization: Basic"
unless the effective AuthType is CUPSD_AUTH_BASIC and
"Authorization: Negotiate" unless it is CUPSD_AUTH_NEGOTIATE in
cupsdAuthorize() in scheduler/auth.c.
CVE-2025-58060.
Fix cupsd failing to start with "cupsdDoSelect() failed - Bad address!"
on hosts whose RLIMIT_NOFILE hard limit is very large but not
RLIM_INFINITY, where the epoll event array allocation fails.
debian/patches/maxfds-limit.patch: cap MaxFDs at 65535 in
scheduler/main.c, backported from upstream Issue #989.
