[package] redsocks: add package

Redsocks is a daemon running on the local system, that will transparently
tunnel any TCP connection via a remote SOCKS4, SOCKS5 or HTTP proxy server. It
uses the system firewall's redirection facility to intercept TCP connections,
thus the redirection is system-wide, with fine-grained control, and does
not depend on LD_PRELOAD libraries.

+  Redsocks is a daemon running on the local system, that will transparently
+  tunnel any TCP connection via a remote SOCKS4, SOCKS5 or HTTP proxy server. It
+  uses the system firewall's redirection facility to intercept TCP connections,
+  thus the redirection is system-wide, with fine-grained control, and does
+  not depend on LD_PRELOAD libraries.
+
+  Redsocks supports tunneling TCP connections and UDP packets. It has
+  authentication support for both, SOCKS and HTTP proxies.
+
+  Also included is a small DNS server returning answers with the "truncated" flag
+  set for any UDP query, forcing the resolver to use TCP.
