Allow Pidgin to use SRV records
Originally created by @hefee on #16528 (Redmine)
A lot of jabber servers use SRV DNS records to provide the correct
server of the jabber server from a jabber UID. The current Proxy setting
within Tails SOCKS5 make it impossible to resolve those SRV records,
because the Tails network does not resolve those requests.
At my work fixing #16348 (closed), it looks like I found a working solution:
Use SOCKS4 without “Remote-DNS over SOCKS4”.
