Andy Green 0517a2a629 ss: split out blob into own minimal example
The --blob option requires GENCRYPTO that's not on by default, to handle
the hash checks... that's going to cause a lot of confusion because it
means the simplest ss example won't build by default then.

Let's remove the blob support (and GENCRYPTO dependency) from the simplest
example and make a new minimal-secure-streams-blob example that has --blob
support and the GENCRYPTO dependency as well.

lws minimal secure streams

The application goes to https://warmcat.com and reads index.html there.

It does it using Secure Streams... the main code in minimal-secure-streams.c just sets up the context and opens a secure stream of type "mintest".

The handler for state changes and payloads for "mintest" is in ss-myss.c

The information about how a "mintest" stream should connect and the protocol it uses is kept separated in policy-database.c

build

 $ cmake . && make

usage

Commandline option Meaning
-d Debug verbosity in decimal, eg, -d15
-f Force connecting to the wrong endpoint to check backoff retry flow
-p Run as proxy server for clients to connect to over unix domain socket
--force-portal Force the SS Captive Portal Detection to feel it's behind a portal
--force-no-internet Force the SS Captive Portal Detection to feel it can't reach the internet
--blob Download a 50MiB blob from warmact.com, using flow control at the proxy
