vi/websocat v1.8.0

Fix some bugs

on GitHub

• --accept-from-fd option for better systemd intergration
• exec:/cmd:/sh-c: specifiers now don't terminate process prematurely
• --foreachmsg-wait-read for better foreachmsg: overlay behaviour. Now foreachmsg:exec:./myscript is more meaningul.
• --basic-auth option to insert basic authentication header more easily
• Websocket close message is now logged in debug mode

Unfortunately, build system for providing prebuilt executables is not reproducible and was only partially automatized; and it is now falling apart - not all artifacts are provided. It may make sense to try previous (including substantially old, e.g. v1.0.0) versions of Websocat's prebuilt executables. Better building situation may arrive with Websocat 3.

OpenSSL is actually static in many versions, even without -static in the name.
