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 http client certinfo

This demonstrates how to dump information from the peer certificate largely independent of the tls backend.

The application goes to https://warmcat.com and receives the page data.

Before receiving the page it dumps information on the server's cert.

This works independently of the tls backend being OpenSSL or mbedTLS.

However the public keys cannot be compared between the two tls backends, since they produce different representations.

build

 $ cmake . && make

usage

Commandline option Meaning
-d Debug verbosity in decimal, eg, -d15
-l Connect to https://localhost:7681 and accept selfsigned cert
--h1 Specify http/1.1 only using ALPN, rejects h2 even if server supports it
