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

0fb976837b tls certs: update warmcat.com and libwebsockets.org public certs
Old certs were getting near the end of their life and we switched the
server to use letsencrypt.  The root and intermediate needed for the
mbedtls case changed accordingly

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

fed78bef42 sequencer: upgrade timeout to use us
Adapt service loops and event libs to use microsecond waits
internally, for hrtimer and sequencer.  Reduce granularity
according to platform / event lib wait.

Add a helper so there's a single place to extend it.

1d954d52a3 sequencer: add second aux message arg
Since the messages are queued and then read in order from the event loop
thread, it's not generally safe to pass pointers to argument structs,
since there's no guarantee the lifetime of the thing sending the message
lasted until the sequencer read the message.

This puts pressure on the single void * argument-passed-as-value... this patch
adds a second void * argument-passed-as-value so it's more possible to put
what's needed directly in the argument.

It's also possible to alloc the argument on the heap and have the sequencer
callback free it after it has read it.

f12e116188 lws_retry_bo_t: generic retry backoff
Add a generic table-based backoff scheme and a helper to track the
try count and calculate the next delay in ms.

Allow lws_sequencer_t to be given one of these at creation time...
since the number of creation args is getting a bit too much
convert that to an info struct at the same time.
