Andy Green d9f982a055 minimal examples: update for CSP best practices 
1) update the logos to svg

2) add svg icon for strict security policy where used

3) define new vhost option flag to enforce sending CSP headers
   with the result code

4) add vhost option flag to minimal examples to
   enforce sending CSP where applicable

5) Go through all the affecting examples confirming they
   still work

6) add LWS_RECOMMENDED_MIN_HEADER_SPACE constant (currently
   2048) to clarify when we need a buffer to hold headers...
   with CSP the headers have become potentially a lot
   larger.

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

usage

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