banip: update 0.2.0

* remove 'http-only' mode, all sources are now fetched from https sites
* the backup mode is now mandatory ('/tmp' is the default backup
  directory), always create and re-use backups if available.
  To force a re-download take the 'reload' action.
* support 'sshd' in addition to 'dropbear' for logfile parsing
  to detect break-in events
* always update the black-/whitelist with logfile parsing results
  in 'refresh' mode (no new downloads)
* rework the return code handling
* tweak procd trigger
* various small fixes
* (s)hellsheck cosmetics

## Main Features
* support many IP blocklist sources (free for private usage, for commercial use please check their individual licenses):
* zero-conf like automatic installation & setup, usually no manual changes needed
* supports six different download utilities: uclient-fetch, wget, curl, aria2c, wget-nossl, busybox-wget
* supports four different download utilities: uclient-fetch, wget, curl, aria2c
* Really fast downloads & list processing as they are handled in parallel as background jobs in a configurable 'Download Queue'
* provides 'http only' mode without installed ssl library for all non-SSL blocklist sources
* full IPv4 and IPv6 support
* ipsets (one per source) are used to ban a large number of IP addresses
* supports blocking by ASN numbers
* supports blocking by iso country codes
* supports local white & blacklist (IPv4, IPv6 & CIDR notation), located by default in /etc/banip/banip.whitelist and /etc/banip/banip.blacklist
* auto-add unsuccessful ssh login attempts to local blacklist (see 'ban_autoblacklist' option)
* auto-add unsuccessful ssh login attempts to 'dropbear' or 'sshd' to local blacklist (see 'ban_autoblacklist' option)
* auto-add the uplink subnet to local whitelist (see 'ban_autowhitelist' option)
* per source configuration of SRC (incoming) and DST (outgoing)
* integrated IPSet-Lookup
* integrated RIPE-Lookup
* blocklist source parsing by fast & flexible regex rulesets
* minimal status & error logging to syslog, enable debug logging to receive more output
* procd based init system support (start/stop/restart/reload/status)
* procd based init system support (start/stop/restart/reload/refresh/status)
* procd network interface trigger support
* automatic blocklist backup & restore, they will be used in case of download errors or during startup in backup mode
* 'backup mode' to re-use blocklist backups during startup, get fresh lists via reload or restart action
* automatic blocklist backup & restore, they will be used in case of download errors or during startup
* output comprehensive runtime information via LuCI or via 'status' init command
* strong LuCI support
* optional: add new banIP sources on your own
## Prerequisites
* [OpenWrt](https://openwrt.org), tested with the stable release series (18.06) and with the latest snapshot
* [OpenWrt](https://openwrt.org), tested with the stable release series (19.07) and with the latest snapshot
* a download utility:
* to support all blocklist sources a full version (with ssl support) of 'wget', 'uclient-fetch' with one of the 'libustream-*' ssl libraries, 'aria2c' or 'curl' is required
* for limited devices with real memory constraints, banIP provides also a 'http only' option and supports wget-nossl and uclient-fetch (without libustream-ssl) as well
* to support all blocklist sources a full version with ssl support of 'wget', 'uclient-fetch' with one of the 'libustream-*' ssl libraries, 'aria2c' or 'curl' is required
## Installation & Usage
* install 'banip' (_opkg install banip_)
* at minimum configure the needed IP blocklist sources, the download utility and enable the banIP service in _/etc/config/banip_
* control the banip service manually with _/etc/init.d/banip_ start/stop/restart/reload/status or use the LuCI frontend
* control the banip service manually with _/etc/init.d/banip_ start/stop/restart/reload/refresh/status or use the LuCI frontend
## LuCI banIP companion package
* it's recommended to use the provided LuCI frontend to control all aspects of banIP
