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.

fed78bef42 sequencer: upgrade timeout to use us
Adapt service loops and event libs to use microsecond waits
internally, for hrtimer and sequencer.  Reduce granularity
according to platform / event lib wait.

Add a helper so there's a single place to extend it.

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.

d7ddd494ea cmake: clang: Fix LWS_WITH_ASAN
Building with LWS_WITH_ASAN was broken when using Clang, due to some
flags being given that Clang doesn't recognize.
Fixed this by adding those flags only when the compiler isn't Clang.

8f5cdac36d Subject: [PATCH] Fix bzero misdetection also for GCC >=8
The fix in 1d6128d1fe worked for
MinGW with GCC7, but GCC8 evidentially got smarter, and it
also substitutes bzero->memset for larger arrays.

Set the emitted warning as an error to avoid misdetection.

1d6128d1fe cmake: Fix bzero mis-detection on MinGW
Using a C compiler ignores non-existent functions, and tries to link them anyway.

The compiler optimizes `bzero(buf, 1)` to `movb   $0x0,0xf(%esp)`, so bzero is
not called at all, and the linker succeeds.

Increase the buffer size to 100 to avoid this optimization.

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.

b50e9fb31b cmake: override build system release optimization policy
The cmake config on the build system actually decides the release build optimization policy.
On Fedora, it's -O2.  On Ubuntu, it's -O3.

Anything given in CMakeLists.txt is overridden by the build system policy since it goes at
the end of the compiler commandline.

When you are building cross, the build system's opinion of your cross binary optimization
level is irrelevant, and at worst destructive.  Some versions of gcc contain broken optimizations
that are applied only at -O3.

This patch removes any doomed attempt to set -O in CMakeLists.txt, which has
no effect since the build system policy is still added at the end, but
removes confusion; and adds code to all the cross build files to forcibly
override release optimization level to -O2, removing the build system's
opinion of how your cross build should look.

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_.
