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.
After https://github.com/warmcat/libwebsockets/pull/1745
Move libev workaround outside the
if ((LWS_ROLE_H1 OR LWS_ROLE_H2) AND NOT LWS_WITHOUT_TESTAPPS) block
otherwise build fails on:
/home/naourr/work/instance-1/output-1/build/libwebsockets-3.2.0/lib/event-libs/libev/libev.c: In function 'lws_ev_hrtimer_cb':

AG: this doesn't really fix anything... the spew is intentionally part of libev.
It just hides the spew... since the maintainer won't fix it
this is the only way AFAIK. Other than don't use libev.

Kernel update changed the /sys path for temp monitoring... the status had
already emitted a , in the json committing it to make a new entry, but the
code skips making it if the file can't be opened.
Change it to produce "(unknown)" in that case.
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.
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
External poll support generates a lot of messages on a busy system
for no value unless you're one of the few people using it. It's
not recommended for new users and is there for backwards compatibility.
Make it not built by default and selectable by cmake option.
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
