Andy Green 4804624905 ss: force check all set_metadata returns 
lws_ss_set_metadata can fail... eg, due to transient OOM situation... if it does,
caller must take appropriate action like disconnect and retry.

So mark the api as requiring the result checking, and make sure all the
examples do it.

lws minimal secure streams hugeurl

This application sends a huge url to httpbin.org, by default 4000 bytes in a urlarg ?x=xxxxxx..., where the argument is a random string in hex.

Notice that httpbin.org has its own limit for urlsize, of 4094 bytes for the entire URL.

build

 $ cmake . && make

usage

Commandline option Meaning
-d Debug verbosity in decimal, eg, -d15
-h Default 4000
--h1 Force http/1.1 instead of default h2
