3f4623bb36 lws_metrics
There are a few build options that are trying to keep and report
various statistics

 - DETAILED_LATENCY
 - SERVER_STATUS
 - WITH_STATS

remove all those and establish a generic rplacement, lws_metrics.

lws_metrics makes its stats available via an lws_system ops function
pointer that the user code can set.

Openmetrics export is supported, for, eg, prometheus scraping.

8e5f8491db opensslv3: handle deprecation of EC apis
openssl v3-alpha11 has marked EC_KEY pieces as deprecated... we use it in
LWS_WITH_GENCRYPTO but the related RSA etc pieces were already deprecated
for that.  We use EC_KEY pieces in vhost init...

The apis are not removed but deprecated, we should have a way to keep
trucking, but as it is the deprecation warning is promoted to an error.

Let's add LWS_SUPPRESS_DEPRECATED_API_WARNINGS option off by default.  If
enabled at cmake, external deprecated api warnings are suppressed.  This
gives a general workaround for now for opensslv3.

In addition, even if you don't do that, let's notice we are on openssl v3
and don't build the EC curve selection stuff, I don't think anyone is
actually using it anyway.

0d588b292c logs: make tag lifecycle optional default on
The elaborated tags for ls owsi, vh, and ss objects are very useful
signposts to understand what's happening in the logs.  But for busy
h1 servers, they're just a lot of noise.

This lets you stop the logging of tagged object lifecycle by cmake

0e6df74409 plugins: add option LWS_WITH_PLUGINS_BUILTIN
Add the ability to just build plugins into the main library.
They are already designed to have a pinhole export for when
they are used as dynamic lib plugins so their namespace
does not conflict.

c9731c5f17 type comparisons: fixes
This is a huge patch that should be a global NOP.

For unix type platforms it enables -Wconversion to issue warnings (-> error)
for all automatic casts that seem less than ideal but are normally concealed
by the toolchain.

This is things like passing an int to a size_t argument.  Once enabled, I
went through all args on my default build (which build most things) and
tried to make the removed default cast explicit.

With that approach it neither change nor bloat the code, since it compiles
to whatever it was doing before, just with the casts made explicit... in a
few cases I changed some length args from int to size_t but largely left
the causes alone.

From now on, new code that is relying on less than ideal casting
will complain and nudge me to improve it by warnings.

9eb4c4fac2 client: rfc6724 dns results sorting
RFC6724 defines an ipv6-centric DNS result sorting algorithm, that
takes route and source address route information for the results
given by the DNS resolution, and sorts them in order of preferability,
which defines the order they should be tried in.

If LWS_WITH_NETLINK, then lws takes care about collecting and monitoring
the interface, route and source address information, and uses it to
perform the RFC6724 sorting to re-sort the DNS before trying to make
the connections.

643a001ed8 roles: netlink
This creates a role for RFC3549 Netlink monitoring.

If the OS supports it (currently, linux) then each pt creates a wsi
with the netlink role and dumps the current routing table at pt init.
It then maintains a cache of the routing table in each pt.

Upon routing table changes an SMD message is issued as an event, and
Captive Portal Detection is triggered.

All of the pt's current connections are reassessed for routability under
the changed routing table, those that no longer have a valid route or
gateway are closed.

c6c7ab2b44 event libs: default to building as dynamically loaded plugins
Event lib support as it has been isn't scaling well, at the low level
libevent and libev headers have a namespace conflict so they can't
both be built into the same image, and at the distro level, binding
all the event libs to libwebsockets.so makes a bloaty situation for
packaging, lws will drag in all the event libs every time.

This patch implements the plan discussed here

https://github.com/warmcat/libwebsockets/issues/1980

and refactors the event lib support so they are built into isolated
plugins and bound at runtime according to what the application says
it wants to use.  The event lib plugins can be packaged individually
so that only the needed sets of support are installed (perhaps none
of them if the user code is OK with the default poll() loop).  And
dependent user code can mark the specific event loop plugin package
as required so pieces are added as needed.

The eventlib-foreign example is also refactored to build the selected
lib support isolated.

A readme is added detailing the changes and how to use them.

625bade63e ss: static policy: dynamic vhost instantiation
Presently a vh is allocated per trust store at policy parsing-time, this
is no problem on a linux-class device or if you decide you need a dynamic
policy for functionality reasons.

However if you're in a constrained enough situation that the static policy
makes sense, in the case your trust stores do not have 100% duty cycle, ie,
are anyway always in use, the currently-unused vhosts and their x.509 stack
are sitting there taking up heap for no immediate benefit.

This patch modifies behaviour in ..._STATIC_POLICY_ONLY so that vhosts and
associated x.509 tls contexts are not instantiated until a secure stream using
them is created; they are refcounted, and when the last logical secure
stream using a vhost is destroyed, the vhost and its tls context is also
destroyed.

If another ss connection is created that wants to use the trust store, the
vhost and x.509 context is regenerated again as needed.

Currently the refcounting is by ss, it's also possible to move the refcounting
to be by connection.  The choice is between the delay to generate the vh
being visisble at logical ss creation-time, or at connection-time.  It's anyway
not preferable to have ss instantiated and taking up space with no associated
connection or connection attempt underway.

NB you will need to reprocess any static policies after this patch so they
conform to the trust_store changes.

6762c7367f remove: old esp32 helper pieces
The old esp32 -factory stuff along with the lws support doesn't have a
future in its old form.  It has users but the ratio of effort to
contribution is really especially bad.  I haven't updated it for more
than a year since esp-idf changes broke the original stuff.

Freertos plat is alive and well and getting a lot of new use, ESP-32 is
supported both there and by modern lws_drivers pieces, including in CI
on real hardware, any further effort will be invested in that direction
instead of more vendor api-specific code (outside of wrapper
implementation).

lws_drivers wraps any SDK apis in generic lws apis such that your code
just uses those, enabling it to become SDK / SoC / vendor independent.
Its first implementation is on esp-idf, the low and mid-level features
that were in the old -factory are already available using that and
new technologies like lws_struct and Secure Streams.

599625be34 remove: generic sessions
As far as I know there are no users of this, although it worked
it's basically unmaintainable due to handling the sql and JSON
manually.

Gradually better capabilities have appeared in lws, like
lws_struct abstracting out the sql and JSON, and now generic
JWT... these have been used in Sai to great effect and displaced
the only organic would-be user of this.

There is a better path to do this stuff now and no point keeping
this around.

15ce46d971 drivers: initial generic gpio and i2c plus bitbang
Make a start on generic peripheral and bus drivers to provide
meta-functionality regardless of platform.

On the one hand this simply provides...

 - bitbang i2c on top of esp-idf gpio apis
 - ssd1306 oled chip driver as found on Heltec WB32
 - modifications to the minimal example test for esp32 to use that

... on the other hand, those capabilities are provided by creating:

 - an abstract i2c class object
 - an abstract gpio class object
 - i2c class implementation using the abstract gpio for bitbang
 - an abstract display class object
 - an abstract display state (brightness, animated change,
    on/off/init tracking, autodim after inactive, auto-off /
    blanking after inactive)

... with the intention, eg, you only have to add a platform
implementation for the gpio to be able to use the i2c-based
display drivers and state handling, and i2c bitbang, without
any other modifications.

286cf4357a sul: multiple timer domains
Adapt the pt sul owner list to be an array, and define two different lists,
one that acts like before and is the default for existing users, and another
that has the ability to cooperate with systemwide suspend to restrict the
interval spent suspended so that it will wake in time for the earliest
thing on this wake-suspend sul list.

Clean the api a bit and add lws_sul_cancel() that only needs the sul as the
argument.

Add a flag for client creation info to indicate that this client connection
is important enough that, eg, validity checking it to detect silently dead
connections should go on the wake-suspend sul list.  That flag is exposed in
secure streams policy so it can be added to a streamtype with
"swake_validity": true

Deprecate out the old vhost timer stuff that predates sul.  Add a flag
LWS_WITH_DEPRECATED_THINGS in cmake so users can get it back temporarily
before it will be removed in a v4.2.

Adapt all remaining in-tree users of it to use explicit suls.
