When gateway file contains multiple IPs, generate multipath routes
with nexthop per gateway (weight 1 each). Kernel distributes traffic
per-flow across gateways.

Single gateway:  route replace IP via GW table T
Multiple:        route replace IP table T nexthop via GW1 weight 1 nexthop via GW2 weight 1

Directory name is now a logical group name (egw, ogw) with gateway
and table specified in files, same as routes6.d/. Unify process_v4
and process_v6 into a single process_routes function.

Drop iif interface restriction so policy routes apply to both
forwarded and locally-generated traffic. Suppress harmless
"FIB table does not exist" errors on first flush.

Split .list files into pure-IP (antifilter) and domain lists.
Pure IP files go through cat directly, avoiding slow per-line
bash processing of 155k entries through cat_expanded and is_ipv4.

154k lines of ipresolve.lst made while-read loop extremely slow.
Use grep to instantly separate IPs from domains.

Replace ipset+mangle approach with pure ip route tables.
Configuration via routes.d/ (IPv4) and routes6.d/ (IPv6) directories
where each subdirectory = gateway and .list symlinks = domain/IP lists.

Features:
- Hash-based change detection (skip if lists unchanged)
- Double check: file hash + resolved IPs diff
- Batch route loading via ip -batch
- Automatic cleanup of orphaned state
- --show/--force/--add/--del/--flush options

Also adds is_ipv6() and get_ipv6_list_bulk() to functions.

Add echo before each append (>>) to ensure trailing newline,
preventing IP corruption when files are concatenated.

Add get_ipv4_list_bulk() to functions that resolves all domains at once
via adnshost instead of sequential dig calls. Falls back to dig for
domains with deep CNAME chains. DNS resolution: ~134s -> ~6s.

Automatically add HTTP/<FQDN> SPN to machine account and update
keytab when joining domain or refreshing keytab. This allows web
services to use system keytab /etc/krb5.keytab instead of separate
service account keytabs.

- Remove --use-kerberos=required from leave (doesn't work with broken machine account)
- Replace --use-kerberos=required with -U $ADMIN for join (more reliable)
- Add comment explaining why --use-kerberos=required doesn't work

- Use dnshostname=$(hostname -f) to register correct dNSHostName
  (e.g. host.office.etersoft.ru instead of host.etersoft.ru)
- Replace deprecated -k with --use-kerberos=required
- Add idempotency: check testjoin status before joining
- If already joined, verify keytab has correct FQDN
- If machine account is broken, leave and rejoin

Note: requires msDS-AllowedDNSSuffixes on DC to include the DNS subdomain
