0019b67f8b ws-over-h2: wrong sid on rst_stream
rst_stream is almost always called from the h2 parser... in the case
a ws-over-h2 is closing though, it can't reference the h2n parser sid
context to get the sid to send... it's unrelated at that time.

6de416d811 h2 client: dont leak original user_space for network wsi
When creating the stream from the nwsi, the stream was created with
its own user_space that gets overwritten with the nwsi one as it is
demoted to be the stream.

Stop that leaking.

d1d313b4bf ws proxy: also proxy h1 ws to h1 and h2
lws has been able to proxy h2 or h1 inbound connections to an
h1 onward connection for a while now.  It's simple to use just
build with LWS_WITH_HTTP_PROXY and make a mount where the origin
is the onward connection details.  Unix sockets can also be
used as the onward connection.

This patch extends the support to be able to also do the same for
inbound h2 or h1 ws upgrades to an h1 ws onward connection as well.

This allows you to offer completely different services in a
common URL space, including ones that connect back by ws / wss.

66b73c680c coverity 192910: check length in h2 header dump
Since the NUL was always taken care of at the end of buf, the worst it could
do was log some junk.  This makes it explicitly log it as oversize separately.

cbb8b1d3e9 LWS_WITH_ASAN
This lets you build using the runtime Address Sanitizer in gcc.

LWS is heavily tested with valgrind routinely during development.  But ASAN
did find some theoretical-only issues with shifting, strictly ~(1 << 31) is
a signed int, it should be ~(1u << 31).  Gcc does the same for both, but it's
good to have the ability to find these.

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.

ac3bd36c60 vhost_destroy: use vhost wsi reference counting to trigger destroy
This changes the vhost destroy flow to only hand off the listen
socket if another vhost sharing it, and mark the vhost as
being_destroyed.

Each tsi calls lws_check_deferred_free() once a second, if it sees
any vhost being_destroyed there, it closes all wsi on its tsi on
the same vhost, one time.

As the wsi on the vhost complete close (ie, after libuv async close
if on libuv event loop), they decrement a reference count for all
wsi open on the vhost.  The tsi who closes the last one then
completes the destroy flow for the vhost itself... it's random
which tsi completes the vhost destroy but since there are no
wsi left on the vhost, and it holds the context lock, nothing
can conflict.

The advantage of this is that owning tsi do the close for wsi
that are bound to the vhost under destruction, at a time when
they are guaranteed to be idle for service, and they do it with
both vhost and context locks owned, so no other service thread
can conflict for stuff protected by those either.

For the situation the user code may have allocations attached to
the vhost, this adds args to lws_vhost_destroy() to allow destroying
the user allocations just before the vhost is freed.

27e86e2641 cmake: allow setting LWS_ROLE_WS
You can build lws without support for ws, with -DLWS_ROLE_WS=0.

This is thanks to the role ops isolating all the ws-specific business
in the ws role.

Also retire more test apps replaced by minmal-examples.

1d2094996e refactor: absorb other caches into buflist
1) Remove the whole ah rxbuf and put things on to the wsi buflist

This eliminates the whole detachability thing based on ah rxbuf
state... ah can always be detached.

2) Remove h2 scratch and put it on the wsi buflist

3) Remove preamble_rx and use the wsi buflist

This was used in the case adopted sockets had already been read.


Basically there are now only three forced service scenarios

 - something in buflist (and not in state LRS_DEFERRING_ACTION)

 - tls layer has buffered rx

 - extension has buffered rx

This is a net removal of around 400 lines of special-casing.

8829c2f365 selftests
This converts several of the selftests to return a status in their exit code
about whether they 'worked'.

A small bash script framework is added, with a selftest.sh in the mininmal
example dirs that support it, and a ./minimal-examples/selftests.sh script
that can be run from the build dir with no args that discovers and runs all
the selftest.sh scripts underneath.

That is also integrated into travis and the enabled tests must pass now for
travis to pass.  Travis does not have a modern libuv so it can't run a
couple of tests which are nulled out if it sees it's running in travis env.

4b7144f763 lws_buflist
For h1 / ws, a combination of removing POLLIN wait and
stashing any unused rx lets us immediately respond to
rx flow control requests in a simple and effective way,
because the tcp socket is the stream.

But for muxed protocols like h2, that technique cannot
be used because we cannot silence the whole bundle of
streams because one can't handle any more rx dynamically.

There are control frames and content for other streams
serialized inbetween the flow controlled stream content.
We have no choice but to read to so we can see the other
things.  Therefore for muxed protocols like h2 and spdy,
rx flow control boils down to tx credit manipulation
on individual streams to staunch the flow at the peer.

However that requires a round trip to take effect, any
transmitted packets that were in flight before the tx credit
reduction arrives at the remote peer are still going to come
and have to be dealt with by adding them to the stash.

This patch introduces lws_buflist scatter-gather type
buffer management for rxflow handling, so we can append
buffer segments in a linked-list to handle whatever rx
is unavoidably in flight on a stream that is trying to
assert rx flow control.
