3a31c47fcd ws: setting default protocol index to an illegal index disables default ws binding
On lwsws, incoming ws connections to the default vhost
are not rejected by the dummy protocol handler and not
really serviced either, leading to bots connecting to it to
get immortal, idle ws connections with no timeout (since it's an
established ws connection).

Rejecting these connections by default by adding a handler
for ESTABLISHED in the dummy handler will solve it nicely,
but it will break an unknown number of dumb. protocol-less
user implementations that rely on this behaviour by using
break; from their own ESTABLISHED handler and calling
through to the currently NOP dummy handler one.

Add support to assertively disable the default protocol
index used for subprotocol-less ws connections instead.

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-
