Now we are building with -O0 -g and debug enabled by default.
--disable-debug in configure will get you a -04 without -g

This exposes the library version and git head hash it was built from
into LWS_LIBRARY_VERSION and LWS_BUILD_HASH.
These are combined into a version string that's both printed as a
notice log by the library and made available to the app using a new
api lws_get_library_version(). The version looks like
1.1 178d78c

Libwebsockets is fundamentally singlethreaded... the existence of the
fork and broadcast support, especially in the sample server is
giving the wrong idea about how to use it.
This replaces broadcast in the sample server with
libwebsocket_callback_on_writable_all_protocol(). The whole idea of
'broadcast' is removed.
All of the broadcast proxy stuff is removed: data must now be sent
from the callback only. Doing othherwise is not reliable since the
service loop may close the socket and free the wsi at any time,
invalidating a wsi pointer held by another thread (don't do that!)
Likewise the confirm_legit_wsi api added recently does not help the
other thread case, since if the wsi has been freed dereferencing the
wsi to study if it is legit or not will segfault in that case. So
this is removed too.
The overall effect is to push user code to only operate inside the
protocol callbacks or external poll loops, ie, single thread context.

The new --without-extensions config flag completely removes all code
and data related to extensions from the build throughout the library
when given.

Move server-only stuff into their own files and make building
that depend on not having --without-server on the configure
Make fragments in other places conditional as well
Remove client-related members from struct libwebscket when
building LWS_NO_CLIENT
Apps:
normal: build test server, client, fraggle, ping
--without-client: build test server
--without-server: build test client, ping

Unfortunately this code is beginning to rot due to lack of demand to
provide it and it being disabled by default.
If demand appears we can revert this and resume work on it, otherwise
let's bite the bullet for the moment.

This leverages the refactor patches to introduce the ability to
disable building any client side code in the library or the client
side test apps.
This will be a considerable size saving for embedded server-only
case.

David found that uclibc did not provide this slightly esoteric api
and provided one from BSD that can be built by the library internally.

- multiple debug context calls lwsl_ err, warn, debug, parser, ext, client
- api added to set which contexts output to stderr using a bitfield log_level
- --disable-debug on configure removes all code that is not err or warn severity
- err and warn contexts always output to stderr unless disabled by log_level
- err and warn enabled by default in log_level

This is initial x-google-mux support. It's disabled by default
since it's very pre-alpha.
1) To enable it, reconfigure with --enable-x-google-mux
2) It conflicts with deflate-stream, use the -u switch on
the test client to disable deflate-stream
3) It deviates from the google standard by sending full
headers in the addchannel subcommand rather than just
changed ones from original connect
4) Quota is not implemented yet
5) Close of subchannel is not really implemented yet
6) Google opcode 0xf is changed to 0x7 to account for
v7 protocol changes to opcode layout
However despite those caveats, in fact it can run the
test client reliably over one socket (both dumb-increment
and lws-mirror-protocol), you can open a browser on the
same test server too and see the circles, etc.
