5a937fa830 lws_json_simple_find and lws_nstrstr
String helpers for scanning non-NUL-delimited strings safely,
and very cheap simple string match based JSON parse for cases
that make sense for it... for more complex cases, do a full
JSON parse.

a0535d010c sai.json: reduce riscv qemu builds
These are really slow since the processor itself is emulated... if it's broken,
it will break on the most complex configurations, configuration conflicts will
be flushed out by building on native arch anyway.  So just build the complex
configuration on Risc-V.

ac6edaf199 lws_strexp: add ability to find output length without write
Sometimes we need to find out the substituted length before we can
allocate and actually store it.  Teach strexp that if we set the
output buffer to NULL (and the output length to something big) we
are asking for the substituted length and to not produce output.

30e6c22e14 openssl3: migrate genhmac to EVP
The low level apis for HMAC (including those only introduced at 1.1.0...)
are all deprecated in OpenSSL v3.

Let's bite the bullet and migrate to EVP, it's already existing in modern
OpenSSL and we already use it for genhash.

EVP needs a PKEY, sort that out and keep it around until the hmac is
destroyed.

15ce46d971 drivers: initial generic gpio and i2c plus bitbang
Make a start on generic peripheral and bus drivers to provide
meta-functionality regardless of platform.

On the one hand this simply provides...

 - bitbang i2c on top of esp-idf gpio apis
 - ssd1306 oled chip driver as found on Heltec WB32
 - modifications to the minimal example test for esp32 to use that

... on the other hand, those capabilities are provided by creating:

 - an abstract i2c class object
 - an abstract gpio class object
 - i2c class implementation using the abstract gpio for bitbang
 - an abstract display class object
 - an abstract display state (brightness, animated change,
    on/off/init tracking, autodim after inactive, auto-off /
    blanking after inactive)

... with the intention, eg, you only have to add a platform
implementation for the gpio to be able to use the i2c-based
display drivers and state handling, and i2c bitbang, without
any other modifications.

280584ff8f ipv6: support interface name for scope lookup
Currently for ipv6, we look up the scope assuming we were given an interface ip for
binding.  But with ipv4, we also support giving an interface name.

Check it against an interface name first and return that if valid.

2a772776a9 windows: for data exports use explicit extern

698eda63d7 ss: formalize user cb retcodes
It's not safe to destroy objects inside a callback from a parent that
still has references to the object.

Formalize what the user code can indicate by its return code from the
callback functions and provide the implementations at the parents.

 - LWSSSSRET_OK:            no action, OK
 - LWSSSSRET_DISCONNECT_ME: disconnect the underlying connection
 - LWSSSSRET_DESTROY_ME:    destroy the ss object
 - LWSSSSRET_TX_DONT_SEND:  for tx, give up the tx opportunity since nothing to send

e4ab18342a ss: allow NULL cbs
Some streamtypes do not pass or receive payload meaningfully.  Allow them
to just leave their related cb NULL.  Ditto for state, although I'm not sure
how useful such a streamtype can be.

ca3380fd56 deprecation: remove lws_dll1
lws_dll2 has been available for a couple of years and lws_dll1 marked as
deprecated since v3.2.  Remove it.

If it affects you, lws_dll2 has an almost identical api but has more
features, such as storing in the lws_dll2_t which owner it is listed by
and keeping a count of objects on the list at the owner object.

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.

3d8b2f9d88 docs: add bug report template md
The ease of dropping bug reports is making it a bit asymmetrical
in terms of the complexity of even trying to figure out what is
being told, let alone writing a reproducer and trying it.

Ask for more effort from reporters and provide "first aid"
suggestions and filtering in the template, so at least some of
the support requests will get fixed by people doing that
before I need to hear about it.

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

cabe021955 esp32: shift to support latest esp-idf
Esp-idf has an improved but still kind of abused cmake-
based build system now.

If we see ESP_PLATFORM coming as a cmake var, we can know we
are being built from inside the esp-idf config system.

Leave the existing esp32 arrangements alone but triggered off
ESP_PLATFORM, adapt to use the cross toolchain file and
various quirks automatically.

In this way you can build lws a part of your project in a
much cleaner way.

Prepare a minimal esp32 test app for use in Sai

Adapt .sai.json to build for esp32
