b6004e08c9 mqtt: allow indicating client_id is not on heap
Not sure why we don't leave any freeing to the caller, but since we don't
allow indicating that the provided client id should not be freed.

fabe78d222 Wextra
Add -Wextra (with -Wno-unused-parameter) to unix builds in addition to
-Wall -Werror.

This can successfully build everything in Sai without warnings / errors.

06662a64fa LE-root-cert-update
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.

https://letsencrypt.org/2020/09/17/new-root-and-intermediates.html

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.

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.

4cd381f933 cmake: tls: wolfssl
PARENT_SCOPE needs adjusting in a few places for wolfssl to work, and
we need a second level export of USE_WOLFSSL through lib/CMakeLists.txt

Add noi/f32 Sai build for WOLFSSL + MINIMAL_EXAMPLES

b3131fdfdd cmakelist: Augean Stables refactor
Establish a new distributed CMake architecture with CMake code related to
a source directory moving to be in the subdir in its own CMakeLists.txt.
In particular, there's now one in ./lib which calls through to ones
further down the directory tree like ./lib/plat/xxx, ./lib/roles/xxx etc.

This cuts the main CMakelists.txt from 98KB -> 33KB, about a 66% reduction,
and it's much easier to maintain sub-CMakeLists.txt that are in the same
directory as the sources they manage, and conceal all the details that that
level.

Child CMakelists.txt become responsible for:

 - include_directories() definition (this is not supported by CMake
   directly, it passes it back up via PARENT_SCOPE vars in helper
   macros)

 - Addition child CMakeLists.txt inclusion, for example toplevel ->
   role -> role subdir

 - Source file addition to the build

 - Dependent library path resolution... this is now a private thing
   in the child CMakeLists.txt, it just passes back any adaptations
   to include_directories() and the LIB_LIST without filling the
   parent namespace with the details

d3308df40f windows: pthreads
Add support for external pthreads lib on windows and some docs about how to do.

It can build with LWS_WITH_THREADPOOL and LWS_WITH_MINIMAL_EXAMPLES including the
pthreads-dependent ones without warnings or errors on windows platform as well with this.

pthreads_t can be anything, including a struct - not a pointer-to-a-struct
but the struct itself.  These can't be cast to a void * for printing as they can
on linux, where the base type is a pointer.

Let's fix all the usage of those to determine their own thread index in terms
of the meaning to the program rather than as a tid.

9d099ba7be client: MQTT
Adds client support for MQTT QoS0 and QoS1, compatible with AWS IoT

Supports stream binding where independent client connections to the
same endpoint can mux on a single tcp + tls connection with topic
routing managed internally.
