History
Andy Green b3131fdfdd cmakelist: Augean Stables refactor 
Establish a new distributed CMake architecture with CMake code related to
a source directory moving to be in the subdir in its own CMakeLists.txt.
In particular, there's now one in ./lib which calls through to ones
further down the directory tree like ./lib/plat/xxx, ./lib/roles/xxx etc.

This cuts the main CMakelists.txt from 98KB -> 33KB, about a 66% reduction,
and it's much easier to maintain sub-CMakeLists.txt that are in the same
directory as the sources they manage, and conceal all the details that that
level.

Child CMakelists.txt become responsible for:

 - include_directories() definition (this is not supported by CMake
   directly, it passes it back up via PARENT_SCOPE vars in helper
   macros)

 - Addition child CMakeLists.txt inclusion, for example toplevel ->
   role -> role subdir

 - Source file addition to the build

 - Dependent library path resolution... this is now a private thing
   in the child CMakeLists.txt, it just passes back any adaptations
   to include_directories() and the LIB_LIST without filling the
   parent namespace with the details

lws minimal raw fallback http server

This is the same as the minimal http server, with one difference... if you connect to localhost:7681 with something that doesn't send recognizable http, then the connection will be switched to a raw-skt role and bind to a protocol that echoes anything sent back to the sender.

build

 $ cmake . && make

usage

Commandline option Meaning
-d Debug verbosity in decimal, eg, -d15
-s Configure the server for tls / https and LWS_SERVER_OPTION_ALLOW_NON_SSL_ON_SSL_PORT
-h (needs -s) Configure the vhost also for LWS_SERVER_OPTION_ALLOW_HTTP_ON_HTTPS_LISTENER, allowing http service on tls port (caution... it's insecure then)
-u (needs -s) Configure the vhost also for LWS_SERVER_OPTION_REDIRECT_HTTP_TO_HTTPS, so the server issues a redirect to https to clients that attempt to connect to a server configured for tls with http. 
 $ ./lws-minimal-raw-fallback-http-server
[2018/11/29 14:27:34:3014] USER: LWS minimal raw fallback http server | visit http://localhost:7681
[2018/11/29 14:27:34:3243] NOTICE: Creating Vhost 'default' port 7681, 1 protocols, IPv6 off

Visit http://127.0.0.1:7681

This allows testing of various combinations of special features for unexpected content on an http(s) listening socket.
