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-

bce8cca042 refactor: also migrate tls to the ops struct and private.h pattern
Several new ops are planned for tls... so better to bite the bullet and
clean it out to the same level as roles + event-libs first.

Also adds a new travis target "mbedtls" and all the tests except
autobahn against mbedtls build.

exposed.

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.

7b227eb333 autobahn fixes
This replaces the old test-app for echo with separate client and server
minimal versions.

The autobahn test script is made more autonomous and tests both
client and server.

3f683351b3 refactor: split out private role header content
Private header stuff specific to roles should go in the
role dir and only be included if the role is enabled for
build.

Only definitions related to lws core should go in the actual
private-libwebsockets.h

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.

4b7144f763 lws_buflist
For h1 / ws, a combination of removing POLLIN wait and
stashing any unused rx lets us immediately respond to
rx flow control requests in a simple and effective way,
because the tcp socket is the stream.

But for muxed protocols like h2, that technique cannot
be used because we cannot silence the whole bundle of
streams because one can't handle any more rx dynamically.

There are control frames and content for other streams
serialized inbetween the flow controlled stream content.
We have no choice but to read to so we can see the other
things.  Therefore for muxed protocols like h2 and spdy,
rx flow control boils down to tx credit manipulation
on individual streams to staunch the flow at the peer.

However that requires a round trip to take effect, any
transmitted packets that were in flight before the tx credit
reduction arrives at the remote peer are still going to come
and have to be dealt with by adding them to the stash.

This patch introduces lws_buflist scatter-gather type
buffer management for rxflow handling, so we can append
buffer segments in a linked-list to handle whatever rx
is unavoidably in flight on a stream that is trying to
assert rx flow control.

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.

This only refactors internal architecture and representations, the user
api is unaffected.
