There was not really any "connection failure" with some of these like 404.
They may have body content that is important.
The client should use lws_http_client_http_response(wsi) to discover
the response code the client action received and decide for itself
what to do about that.
HTTP/2 support is now able to serve the test server, complete with
websockets, from a single vhost.
- This works the same with both OpenSSL and mbedTLS.
- POST is now wired up and works (also for file upload).
- CGI is wired up and works.
- Redirect is adapted and works
- lwsws works.
- URI urldecode, sanitation and argument parsing wired up for :path
valgrind clean (aside from openssl-style false uninit data usage in mbedtls send occasionally)

ssl: fix infinite loop on client cert verification failure

Caused and fixes Coverity 184887 - 184892
The mbedTLS / OpenSSL wrapper spins for the duration of the
handshake, which is a slow 31ms on my x86_64 box (by comparison
it's ~1ms on actual OpenSSL on the same box).
This doesn't change the 31ms but it stops us spinning during the
accept and has us retry on POLLIN instead like OpenSSL.
Note this also fixes the endemic mismatches in returncode
between mbedTLS and OpenSSL semantics...
For some targets like ESP32, the ah pool is mainly sitting idle wasting memory.
For HTTP/2, if the client sends a series of pipelined headers on different SIDs
that exist simultaneously, there is no way to stall the headers to wait for an
ah, because we must read the stream for stuff like WINDOW_UPDATE on the other
streams.
In both these cases having the ability to free unused ah completely and allocate
more dynamically if there is memory is useful, so this patch makes the ah pool
an initially-empty linked list that allocates on demand up to the "max pool
size" limit from the context info. When nobody wants an ah, it is freed (if
someone was waiting for it, it is directly reused).
For ESP32 it means no large, permanent alloc when lws starts and dynamic alloc
according to how many streams the client opens, which can be controlled by
SETTINGS.
This adds the necessary OpenSSL Apis to the mbedTLS openssl wrapper
to allow ALPN negotiation OpenSSL-style.
The OpenSSL upgrade list format is supported and converted to mbedtls
format at runtime.
Almost all the CMake options begin with LWS_WITH_..., but many of the
symbols passed to lws are LWS_USE_... , this causes neededless confusion,
compounded by the fact that a few CMake options also begin with
LWS_USE_.
This patch globally converts all LWS_USE_... to LWS_WITH_..., so there
is only one prefix to remember in both CMake and the code.
The affected public CMake options are
LWS_USE_BORINGSSL -> LWS_WITH_BORINGSSL
LWS_USE_CYASSL -> LWS_WITH_CYASSL
LWS_USE_WOLFSSL -> LWS_WITH_WOLFSSL
LWS_USE_MBEDTLS -> LWS_WITH_MBEDTLS
LWS_USE_BUNDLED_ZLIB -> LWS_WITH_BUNDLED_ZLIB
