When the number of parallel mbedtls ctest runs exceeds the number of free cpus in the
builder, we get too slow when under valgrind to pass the client tests before they
timeout.
Add -l option on lws-api-test-async-dns that makes it sit there trying to
lookup warmcat.com every 5s until ^C. This is useful to test behaviour
over loss of connectivity and regaining it.
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
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
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.
Add a helper to simplify passing smd ss rx traffic into the local
smd participants, excluding the rx that received it externally to
avoid looping.
Make the smd readme clearer with three diagrams and more explanation
of how the ss proxying works.
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.
This adds some new objects and helpers for keeping and logging
info on grouped allocations, a group is, eg, SS handles or client
wsis.
Allocated objects get a context-unique "tag" string intended to replace
%p / wsi pointers etc. Pointers quickly become confusing when
allocations are freed and reused, the tag string won't repeat
until you produce 2^64 objects in a context.
In addition the tag string documents the object group, with prefixes
like "wsi-" or "vh-" and contain object-specific additional
information like the vhost name, address / port or the role of the wsi.
At creation time the lws code can use a format string and args
to add whatever group-specific info makes sense, eg, a wsi bound
to a secure stream can also append the guid of the secure stream,
it's copied into the new object tag and so is still available
cleanly after the stream is destroyed if the wsi outlives it.
Since client_connect and request_tx can be called from code that expects
the ss handle to be in scope, these calls can't deal with destroying the
ss handle and must pass the lws_ss_state_return_t disposition back to
the caller to handle.
