Filter Cloudflare IPs in legacy mode

Browse Source 
Add support for REJECT_CLOUDFLARE_IPS in legacy config and fetch
Cloudflare
IP ranges to drop matching detected addresses. Improve IP detection in
legacy mode by using literal-IP primary trace URLs with hostname
fallbacks, binding dedicated IPv4/IPv6 HTTP clients, and setting a Host
override for literal-IP trace endpoints so TLS SNI works. Expose
build_split_client and update tests accordingly.
