5c0b0450f2 client: bind and drop protocol like server
HTTP server protocols have had for a while LWS_CALLBACK_HTTP_DROP/BIND_PROTOCOL
callbacks that mark when a wsi is attched to a protocol and detached.

It turns out this is generally useful for everything to know when a wsi is
joining a protocol and definitively completely finished with a protocol.

Particularly with client wsi where you provided the userdata externally, this
makes a clear point to free() it on the protocol binding being dropped.

This patch adds protocol bind / unbind callbacks to the role definition and
lets them operate on all roles.  For the various roles

HTTP server: LWS_CALLBACK_HTTP_BIND/DROP_PROTOCOL as before
HTTP client: LWS_CALLBACK_CLIENT_HTTP_BIND/DROP_PROTOCOL
ws server:   LWS_CALLBACK_WS_SERVER_BIND/DROP_PROTOCOL
ws client:   LWS_CALLBACK_WS_CLIENT_BIND/DROP_PROTOCOL
raw file:    LWS_CALLBACK_RAW_FILE_BIND/DROP_PROTOCOL
raw skt:     LWS_CALLBACK_RAW_SKT_BIND/DROP_PROTOCOL

502130d999 refactor: split out adoption and client apis to core
- split raw role into separate skt and file

 - remove all special knowledge from the adoption
   apis and migrate to core

 - remove all special knowledge from client_connect
   stuff, and have it discovered by iterating the
   role callbacks to let those choose how to bind;
   migrate to core

 - retire the old deprecated client apis pre-
   client_connect_info

27e86e2641 cmake: allow setting LWS_ROLE_WS
You can build lws without support for ws, with -DLWS_ROLE_WS=0.

This is thanks to the role ops isolating all the ws-specific business
in the ws role.

Also retire more test apps replaced by minmal-examples.

1d2094996e refactor: absorb other caches into buflist
1) Remove the whole ah rxbuf and put things on to the wsi buflist

This eliminates the whole detachability thing based on ah rxbuf
state... ah can always be detached.

2) Remove h2 scratch and put it on the wsi buflist

3) Remove preamble_rx and use the wsi buflist

This was used in the case adopted sockets had already been read.


Basically there are now only three forced service scenarios

 - something in buflist (and not in state LRS_DEFERRING_ACTION)

 - tls layer has buffered rx

 - extension has buffered rx

This is a net removal of around 400 lines of special-casing.

aa816e98a9 alpn: assemble defaults from roles and allow override
Since new roles may be incompatible with http, add support for
alpn names at the role struct, automatic generation of the
default list of alpn names that servers advertise, and the
ability to override the used alpn names per-vhost and per-
client connection.

This not only lets you modulate visibility or use of h2,
but also enables vhosts that only offer non-http roles,
as well as restricting http role vhosts to only alpn
identifiers related to http roles.

126be3ccf3 refactor role ops
This only refactors internal architecture and representations, the user
api is unaffected.
