498a4e2bd7 sul: all timed objects use a single pt sul list
wsi timeout, wsi hrtimer, sequencer timeout and vh-protocol timer
all now participate on a single sorted us list.

The whole idea of polling wakes is thrown out, poll waits ignore the
timeout field and always use infinite timeouts.

Introduce a public api that can schedule its own callback from the event
loop with us resolution (usually ms is all the platform can do).

Upgrade timeouts and sequencer timeouts to also be able to use us resolution.

Introduce a prepared fakewsi in the pt, so we don't have to allocate
one on the heap when we need it.

Directly handle vh-protocol timer if LWS_MAX_SMP == 1

45ec3ce369 lws_dll: upgrade all instances to lws_dll2
lws_dll2 removes the downsides of lws_dll and adds new features like a
running member count and explicit owner type... it's cleaner and more
robust (eg, nodes know their owner, so they can casually switch between
list owners and remove themselves without the code knowing the owner).

This deprecates lws_dll, but since it's public it allows it to continue
to be built for 4.0 release if you give cmake LWS_WITH_DEPRECATED_LWS_DLL.

All remaining internal users of lws_dll are migrated to lws_dll2.

d1d313b4bf ws proxy: also proxy h1 ws to h1 and h2
lws has been able to proxy h2 or h1 inbound connections to an
h1 onward connection for a while now.  It's simple to use just
build with LWS_WITH_HTTP_PROXY and make a mount where the origin
is the onward connection details.  Unix sockets can also be
used as the onward connection.

This patch extends the support to be able to also do the same for
inbound h2 or h1 ws upgrades to an h1 ws onward connection as well.

This allows you to offer completely different services in a
common URL space, including ones that connect back by ws / wss.

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
