Andy Green f7149e90c2 cc0: align dedication to CC0 FAQ recommended format 
https://libwebsockets.org/pipermail/libwebsockets/2019-April/007937.html

thanks to Bruce Perens for noting it.

This doesn't change the intention or status of the CC0 files, they were
pure CC0 before (ie, public domain) and they are pure CC0 now.  It just
gets rid of the (C) part at the top of the dedication which may be read
to be a bit contradictory since the purpose is to make it public domain.

lws minimal http server multivhost

This creates a single server that creates three vhosts listening on both :7681 and :7682. Two separate vhosts share listening on :7682.

vhost listens on port serves
localhost1 7681 ./mount-origin-localhost1
localhost2 7682 ./mount-origin-localhost2
localhost3 7682 ./mount-origin-localhost3

Notice the last two both listen on 7682. If you visit http://localhost:7682, by default you will get mapped to the first one, localhost2.

However if you edit /etc/hosts on your machine and add

127.0.0.1 localhost3

so that you can visit http://localhost3:7682 in your browser, lws will use the Host: localhost3 header sent by your browser to select the localhost3 vhost for the connection, and you will be served content from ./mount-origin-localhost3

build

 $ cmake . && make

Commandline option Meaning
-d Debug verbosity in decimal, eg, -d15
--die-after-vhost For testing failure handling
