Andy Green c9731c5f17 type comparisons: fixes 
This is a huge patch that should be a global NOP.

For unix type platforms it enables -Wconversion to issue warnings (-> error)
for all automatic casts that seem less than ideal but are normally concealed
by the toolchain.

This is things like passing an int to a size_t argument.  Once enabled, I
went through all args on my default build (which build most things) and
tried to make the removed default cast explicit.

With that approach it neither change nor bloat the code, since it compiles
to whatever it was doing before, just with the casts made explicit... in a
few cases I changed some length args from int to size_t but largely left
the causes alone.

From now on, new code that is relying on less than ideal casting
will complain and nudge me to improve it by warnings.

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
