On OSX, POLLHUP is always |POLLIN, even if you did not wait
on POLLIN. This causes a loop because we don't want to
ack the POLLHUP until we cleared any pollin (but there is
no pending POLLIN...)
Also prioritize LD_LIBRARY_PATH check for plugins first
Iterate through paths in LD_LIBRARY_PATH in order
Warn on failed plugins init but continue protocol init
Add wsi tags for dbus role, also dbus may add a watcher in a disabled
state, don't action it if so on the lws event loop. It'll re-add
if it wants it, confusingly.
This just runs each of the eventlib-foreign cases that are enabled, it doesn't
do a client action during the test yet since that's hard to arrange with ctest,
but it will catch most breakage.
Change the LD_LIBRARY_PATH order when looking for evlib plugins, so that it
searches there first, if given
On h2 server POST, there's a race to see if the POST body is going to be
received coalesced with the headers.
The problem is on h2, we can't action the stream http request or body until
the stream is writeable, since we may start issuing the response right away;
there's already DEFERRING_ACTION state to manage this. And indeed, the
coalesced, not-immediately-actionable POST body is buflisted properly.
However when we come to action the POST using buflisted data, we don't follow
the same pattern as dealing with the incoming data immediately.
This patch aligns the pattern dumping the buflist content to track
expected rx_content_length and handle BODY_COMPLETION if we got to
the end of it, along with removal from the pt list of wsi with pending
buflists if we used it up.
warmcat.com and libwebsockets.org use Let's Encrypt certificates... LE
have changed their CA signing arrangements and after 2021-01-12 (the
point I renewed the LE server certs and received one signed using the
new arrangements) it's required to trust new root certs for the examples
to connect to warmcat.com and libwebsockets.org.

This updates the in-tree CA copies, the remote policies on warmcat.com
have also been updated.
Just goes to show for real client infrastructure, you need to run your own
CA (that doesn't have to be trusted by anything outside the clients)
where you can control the CA lifetime.
If the server is very close in rtt to the client, the server
hangup may get processed before buffered rx.
Make sure we clear buffered rx before dealing with the HUP.
The various stream transitions for direct ss, SSPC, smd, and
different protocols are all handled in different code, let's
stop hoping for the best and add a state transition validation
function that is used everywhere we pass a state change to a
user callback, and knows what is valid for the user state()
callback to see next, given the last state it was shown.
Let's assert if lws manages to violate that so we can find
where the problem is and provide a stricter guarantee about
what user state handler will see, no matter if ss or sspc
or other cases.
To facilitate that, move the states to start from 1, where
0 indicates the state unset.
Let's allow the proxy to pass back what the policy says about
the size of dsh buffer the client side of this streamtype
should have.
Defer clientsize dsh generation until we got the info back
from the proxy in the response to the initial packet. If
it's zero / unset in the policy, just go with 32KB.
