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.

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.

be32d0554e mbedtls: attempt to remove dependency on net_sockets.c
The mbedtls openssl wrapper wants to use exports from mbedtls' net_sockets.c,
but this is only supposed to work on *nix and windows.  Typically people
are using mbedtls on RTOS type platforms and to use it, net_sockets.c
needs some hacking.

Try to avoid that situation by porting the two exports we need into the
lws plat code and call from the wrapper.

9a1f184915 rtos diet: http: remove headers at buildtime according to config
Headers related to ws or h2 are now elided if the ws or h2 role
is not enabled for build.  In addition, a new build-time option
LWS_WITH_HTTP_UNCOMMON_HEADERS on by default allows removal of
less-common http headers to shrink the parser footprint.

Minilex is adapted to produce 8 different versions of the lex
table, chosen at build-time according to which headers are
included in the build.

If you don't need the unusual headers, or aren't using h2 or ws,
this chops down the size of the ah and the rodata needed to hold
the parsing table from 87 strings / pointers to 49, and the
parsing table from 1177 to 696 bytes.

08fac7a1f7 unix: sul schedule rename internal api and call regardless of existing timeout
Pre-sul, checking for interval to next pending scheduled event was expensive and
iterative, so the service avoided it if the wait was already 0.

With sul though, the internal "check" function also services ripe events and
removes them, and finding the interval to the next one is really cheap.

Rename the "check" function to __lws_sul_service_ripe() to make it clear it's
not just about returning the interval to the next pending one.  And call it
regardless of if we already decided we are not going to wait in the poll.

a97347a18e service: resurrect timeout_ms being -1 as return immediately
There's no longer any reason to come out of sleep for periodic service
which has been eliminated by lws_sul.

With event libs, there is no opportunity to do it anyway since their
event loop is atomic and makes callbacks and sleeps until it is stopped.

But some users are relying on the old poll() service loop as
glue that's difficult to replace.  So for now help that happen by
accepting the timeout_ms of -1 as meaning sample poll and service
what's there without any wait.

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.
