be1be1f342 testapp: extpoll: add back missing EXTERNAL_POLL pieces
EXTERNAL_POLL is not recommended for use for a while, it's a hack to allow
integration of lws with random application poll() loops.

While lws is very happy to do that secondary job for any event lib using the
foreign loop support (for uv, event, glib, and ev), for random roll-your-
own poll() waits there's no api because there's no event lib.  The solution
with a future is upgrade your application to use an event loop.

The test app that supports EXTERNAL_POLL was broken in Apr 2018, so it's
apparently good news nobody has been using it in new implementations
since then.  This patch adds in the missing pieces so we can test it until
it is formally deprecated.

2a772776a9 windows: for data exports use explicit extern
LWS_EXTERN needs to be empty for windows when declaring functions in the
headers.  But for data, it needs the explicit extern otherwise on windows
or mingw based builds, it thinks we are redeclaring the data each time.

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

9f1d019352 CTest: migrate and deprecate existing selftest scripts
Replace the bash selftest plumbing with CTest.

To use the selftests, build with -DLWS_WITH_MINIMAL_EXAMPLES=1
and `CTEST_OUTPUT_ON_FAILURE=1 make test` or just
`make test`.

To disable tests that require internet access, also give
-DLWS_CTEST_INTERNET_AVAILABLE=0

Remove travis and appveyor scripts on master.

Remove travis and appveyor decals on README.md.

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

48366de1d1 unix plat: add minimal wsi fd map option
An lws context usually contains a processwide fd -> wsi lookup table.

This allows any possible fd returned by a *nix type OS to be immediately
converted to a wsi just by indexing an array of struct lws * the size of
the highest possible fd, as found by ulimit -n or similar.

This works modestly for Linux type systems where the default ulimit -n for
a process is 1024, it means a 4KB or 8KB lookup table for 32-bit or
64-bit systems.

However in the case your lws usage is much simpler, like one outgoing
client connection and no serving, this represents increasing waste.  It's
made much worse if the system has a much larger default ulimit -n, eg 1M,
the table is occupying 4MB or 8MB, of which you will only use one.

Even so, because lws can't be sure the OS won't return a socket fd at any
number up to (ulimit -n - 1), it has to allocate the whole lookup table
at the moment.

This patch looks to see if the context creation info is setting
info->fd_limit_per_thread... if it leaves it at the default 0, then
everything is as it was before this patch.  However if finds that
(info->fd_limit_per_thread * actual_number_of_service_threads) where
the default number of service threads is 1, is less than the fd limit
set by ulimit -n, lws switches to a slower lookup table scheme, which
only allocates the requested number of slots.  Lookups happen then by
iterating the table and comparing rather than indexing the array
directly, which is obviously somewhat of a performance hit.

However in the case where you know lws will only have a very few wsi
maximum, this method can very usefully trade off speed to be able to
avoid the allocation sized by ulimit -n.

minimal examples for client that can make use of this are also modified
by this patch to use the smaller context allocations.

f7149e90c2 cc0: align dedication to CC0 FAQ recommended format
https://libwebsockets.org/pipermail/libwebsockets/2019-April/007937.html

thanks to Bruce Perens for noting it.

This doesn't change the intention or status of the CC0 files, they were
pure CC0 before (ie, public domain) and they are pure CC0 now.  It just
gets rid of the (C) part at the top of the dedication which may be read
to be a bit contradictory since the purpose is to make it public domain.

d9f982a055 minimal examples: update for CSP best practices
1) update the logos to svg

2) add svg icon for strict security policy where used

3) define new vhost option flag to enforce sending CSP headers
   with the result code

4) add vhost option flag to minimal examples to
   enforce sending CSP where applicable

5) Go through all the affecting examples confirming they
   still work

6) add LWS_RECOMMENDED_MIN_HEADER_SPACE constant (currently
   2048) to clarify when we need a buffer to hold headers...
   with CSP the headers have become potentially a lot
   larger.

1f1314160a lws_hdr_copy: ensure enough extra space
Audit all lws_hdr_copy() usages inside lws and make sure we
take care about it failing.

Also since the patch around aggregation of headers by ',',
lws_hdr_copy() needs a little more space in the output buffer,
adjust one place where that caused it to start failing in an
exact-sized buffer.

fd810f198a http proxy: client: unix socket support
This allows the client stuff to understand that addresses beginning with '+'
represent unix sockets.

If the first character after the '+' is '@', it understands that the '@'
should be read as '\0', in order to use Linux "abstract namespace"
sockets.

Further the lws_parse_uri() helper is extended to understand the convention
that an address starting with + is a unix socket, and treats the socket
path as delimited by ':', eg

http://+/var/run/mysocket:/my/path

HTTP Proxy is updated to allow mounts to these unix socket paths.

Proxy connections go out on h1, but are dynamically translated to h1 or h2
on the incoming side.

Proxy usage of libhubbub is separated out... LWS_WITH_HTTP_PROXY is on by
default, and LWS_WITH_HUBBUB is off by default.

d1f9f0ae2d libwebsockets.h: split out into a dir of sub-includes included by libwebsockets.h
This has no effect on user code or backward compatibility.

It moves the in-tree public api header libwebsockets.h from ./lib
to ./include, and introduces a dir ./include/libwebsockets/

The single public api header is split out into 31 sub-headers
in ./include/libwebsockets.  ./include/libwebsockets.h contains
some core types and platform adaptation code, but the rest of it
is now 31 #include <libwebsockets/...>

At install time, /usr/[local/]include/libwebsockets.h is installed
as before, along now with the 31 sub-headers in ...include/libwebsockets/

There's no net effect on user code.

But the api header is now much easier to maintain and study, with 31
topic-based sub headers.
