f8afcd0e5c client: make external http proxying optional
Add LWS_CLIENT_HTTP_PROXYING on by default.  Removing it saves a few
hundred bytes of code and 128 bytes per vhost in heap.

c099e7be92 client: do client stash in a single alloc
Improve the code around stash, getting rid of the strdups for a net
code reduction.  Remove the special destroy helper for stash since
it becomes a one-liner.

Trade several stack allocs in the client reset function for a single
sized brief heap alloc to reduce peak stack alloc by around 700 bytes.

d302198019 external poll: add default-off cmake option
External poll support generates a lot of messages on a busy system
for no value unless you're one of the few people using it.  It's
not recommended for new users and is there for backwards compatibility.

Make it not built by default and selectable by cmake option.

498a4e2bd7 sul: all timed objects use a single pt sul list
wsi timeout, wsi hrtimer, sequencer timeout and vh-protocol timer
all now participate on a single sorted us list.

The whole idea of polling wakes is thrown out, poll waits ignore the
timeout field and always use infinite timeouts.

Introduce a public api that can schedule its own callback from the event
loop with us resolution (usually ms is all the platform can do).

Upgrade timeouts and sequencer timeouts to also be able to use us resolution.

Introduce a prepared fakewsi in the pt, so we don't have to allocate
one on the heap when we need it.

Directly handle vh-protocol timer if LWS_MAX_SMP == 1

3c12fd72e8 unify us sorted waits
There are quite a few linked-lists of things that want events after
some period.  This introduces a type binding an lws_dll2 for the
list and a lws_usec_t for the duration.

The wsi timeouts, the hrtimer and the sequencer timeouts are converted
to use these, also in the common event wait calculation.

45ec3ce369 lws_dll: upgrade all instances to lws_dll2
lws_dll2 removes the downsides of lws_dll and adds new features like a
running member count and explicit owner type... it's cleaner and more
robust (eg, nodes know their owner, so they can casually switch between
list owners and remove themselves without the code knowing the owner).

This deprecates lws_dll, but since it's public it allows it to continue
to be built for 4.0 release if you give cmake LWS_WITH_DEPRECATED_LWS_DLL.

All remaining internal users of lws_dll are migrated to lws_dll2.

e76982a090 boringssl: deal with loss of EVP_PKEY_new_mac_key
Rewrite HMAC stuff to use HMAC_ apis instead of EVP

Bit trickly since modern OpenSSL has opaque HMAC_CTX and older
OpenSSL does not have any apis to allocate and free it.

Add another cmake check for the allocation api to decide
what to do.

119aa5c0ad lws_dir: wrap dir scanning backend and convert lejp-conf
We use POSIX dir scanning apis normally, but for windows, we require libuv
to do it for us.

Formalize that into a wrapper lws_dir() that hides the backend code.

Make it configurable, ON by default and forced on with lejp-conf that
depends on it.

986bb37c88 ah: custom headers for h1
Until now lws only parses headers it knows at build-time from its
prebuilt lexical analyzer.

This adds an on-by-default cmake option and a couple of apis
to also store and query "custom", ie, unknown-to-lws headers.

A minimal example is also provided.

At the moment it only works on h1, h2 support needs improvements
to the hpack implementation.

Since it bloats ah memory usage compared to without it if custom
headers are present, the related code and ah footprint can be
disabled with the cmake option LWS_WITH_CUSTOM_HEADERS, but it's
on by default normally.  ESP32 platform disables it.

a3dcc95471 genec: generic ECDH crypto layer
!!! WIP

This implements the "genec" layer wrapping mbedtls + openssl
ECDH support.

API tests are added for the parts that are implemented so far.

Stuff related to ec at all, like keys, are prefixed lws_genec_.
Stuff specific to ECDH are prefixed lws_genecdh_.

ddb94d4e27 genaes: generic AES layer independent of tls library
Although RSA can be used directly for signing / JWS
on large chunks of data since it's only operating on
the hash, when JWE support arrives, which allows bulk
encryption, it's going to be mandatory to support
secondary AES ciphers to use on the bulk data.

This adds generic support for all AES modes that OpenSSL
and mbedTLS have in common, works on both mbedTLS and
OpenSSL the same, and adds unit tests for each mode
in api-test-gencrypto, to run in CI.

31dfc4aa12 role: dbus
This adds support for the integrating libdbus into the lws event loop.

Unlike the other roles, lws doesn't completely adopt the fd and libdbus insists
to retain control over the fd lifecycle.  However libdbus provides apis for
foreign code (lws) to provide event loop services to libdbus for the fd.

Accordingly, unlike the other roles rx and writeable are not subsumed into
lws callback messages and the events remain the property of libdbus.

A context struct wrapper is provided that is available in the libdbus
callbacks to bridge between the lws and dbus worlds, along with
a minimal example dbus client and server.

d58828692e http: compression methods
Add generic http compression layer eanbled at cmake with LWS_WITH_HTTP_STREAM_COMPRESSION.

This is wholly a feature of the HTTP role (used by h1 and h2 roles) and doesn't exist
outside that context.

Currently provides 'deflate' and 'br' compression methods for server side only.

'br' requires also -DLWS_WITH_HTTP_BROTLI=1 at cmake and the brotli libraries (available in
your distro already) and dev package.

Other compression methods can be added nicely using an ops struct.

The built-in file serving stuff will use this is the client says he can handle it, and the
mimetype of the file either starts with "text/" (html and css etc) or is the mimetype of
Javascript.

zlib allocates quite a bit while in use, it seems to be around 256KiB per stream.  So this
is only useful on relatively strong servers with lots of memory.  However for some usecases
where you are serving a lot of css and js assets, it's a nice help.

The patch performs special treatment for http/1.1 pipelining, since the compression is
performed on the fly the compressed content-length is not known until the end.  So for h1
only, chunked transfer-encoding is automatically added so pipelining can continue of the
connection.

For h2 the chunking is neither supported nor required, so it "just works".

User code can also request to add a compression transform before the reply headers were
sent using the new api

LWS_VISIBLE int
lws_http_compression_apply(struct lws *wsi, const char *name,
			   unsigned char **p, unsigned char *end, char decomp);

... this allows transparent compression of dynamically generated HTTP.  The requested
compression (eg, "deflate") is only applied if the client headers indicated it was
supported, otherwise it's a NOP.

Name may be NULL in which case the first compression method in the internal table at
stream.c that is mentioned as acceptable by the client will be used.

NOTE: the compression translation, same as h2 support, relies on the user code using
LWS_WRITE_HTTP and then LWS_WRITE_HTTP_FINAL on the last part written.  The internal
lws fileserving code already does this.

b45956fcb9 client: add alpn processing on mbedtls and openssl
This just supports "http/1.1" alpn and lets the client know it
can use keepalive earlier if it affirmitively negotiated
"http/1.1" on alpn.

mbedTLS wrapper needed a small adaptation to also allow
per-client-ssl control of the alpn negotiation list.

e4a3e8c4d4 LWS_WITH_MINIMAL_EXAMPLES: default-off build all minimal samples after lws for QA
This adds an lws cmake option that builds all the minimal examples as part of lws,
it's useful for QA.

It adds a macro to examples that depend on a particular lws configuration to understand
they should just null out their project definition in builds where the lws configuration
requirement is not met, and we are building as part of lws.

It also adapts all the example library additions to select the just-built-but-not-yet-installed
library in the case it is built as part of lws.  If built standalone, it now uses the cmake
platform-abstracted way to add the library requirement too.
