Description

Introduced in FreeBSD1 and inherited in DragonFly BSD, cat(1) has the ability to utilise a unix domain socket but the usecase is somewhat limited & better served by other tools eg netcat. Attached diff removes the functionality & restores previous behaviour. This feature is exclusive to FreeBSD & DragonFly BSD and has not been adopted by the other BSDs.

I have actually used this feature before, for test scripts for a network API, but I still support removal because it could reduce attack vectors and attack surface. I use netcat now, just as suggested.
