fixes #1035 Convey is awkward -- consider acutest.h
This represents a rather large effort towards cleaning up our
testing and optional configuration infrastructure.
A separate test library is built by default, which is static, and
includes some useful utilities design to make it easier to write
shorter and more robust (not timing dependent) tests. This also means
that we can cover pretty nearly all the tests (protocols etc.) in
every case, even if the shipped image will be minimized.
Subsystems which are optional can now use a few new macros to configure
what they need see nng_sources_if, nng_headers_if, and nng_defines_if.
This goes a long way to making the distributed CMakefiles a lot simpler.
Additionally, tests for different parts of the tree can now be located
outside of the tests/ tree, so that they can be placed next to the code
that they are testing.
Beyond the enabling work, the work has only begun, but these changes
have resolved the most often failing tests for Darwin in the cloud.

It's possible for an empty chunk to have a NULL data pointer.
Even when copying zero bytes, this makes clang somewhat unhappy.

This removes the default 1MB limit on maximum receive sizes.
Applications intended for deployment in insecure or hostile
environments should choose a sensible default for NNG_OPT_RECVMAXSZ.

This also introduces a more efficient reference counting usage based
on atomics, rather than locks.

The functions nng_dialer_setopt_uint64 and nng_dialer_setopt_uint64 are
declared in nng.h but not defined, causing errors at runtime of programs
that expect them to be defined.

This permits the stats dump to avoid some extra buffering,
and resolves a complaint about possible format buffer overruns.

- Renamed internal nng_*_getx/setx methods with "nni" prefix
- Moved stream get/set option definition macros to options.h and added "NNI_" prefix
- "_PTR" variant of get/set option definition macros is for when first arg is passed as pointer (`nng_stream *s` vs `nng_pipe s`)
- New get/set option functions for `nng_socket` are `nng_socket_get_X` eschewing the previous `nng_getopt` pattern
- Macro-fy legacy getopt/setopt and implement in terms of "new" API
- nng_setopt* use "new" shorter API. Add missing uint64 set functions.
- Shorter get/set option functions get own man page and old getopt/setopt link to them
- Built with -DNNG_ENABLE_DOC=ON and part of central libnng index
- Update copyright

There is quite some package loss, which I will pursue
later (in nng / zerotier). For now it helps to tune these settings
to keep the peer relations.

This also eliminates the enforcement of NNG_OPT_RECVMAXSZ for inproc,
which never really made much sense. This helps inproc go faster.
While here, also clean up the entry point for protocols to support
a drain option, since we don't use that anywhere.

fixes #762 Pub/Sub very slow compared with nanomsg
This introduces contexts for SUB, and converts both the cooked SUB
and PUB protocols to use a new lightweight message queue that has
significant performance benefits over the heavy-weight message queue.
We've also added a test program, pubdrop, in the perf directory,
which can be used for measuring pub/sub message rates and drop rates.
Note that its quite easy to overwhelm a subscriber still.
The SUB socket performance is still not completely where it needs to be.
There are two remainging things to improve. Firsst we need to replace
the naive linked list of topics with a proper PATRICIA trie. Second, we
need to work on the low level POSIX poller code. (The Windows code is
already quite good, and we outperform nanomsg on Windows.)

fixes #698 Need TCP stats
fixes #699 Need IPC stats
fixes #701 Need TLS stats
This commit addresses a problem when negotiating using one of the stream
based negotiation APIs -- a slow or misbehaving peer can prevent well
behaved ones from establishing a connection. The fix is a fairly
significant change in how these transports link up, and it does rely
on the fact that the socket only has a single accept() or connect()
pending at a time (on a given endpoint that is).
While here, we have completely revamped the way transport statistics are
done, offering a standard API for collecting these statistics.
Unfortunately, this completely borks the statistics for inproc. As we
are planning to change the way inproc works soon, in order to provide
more control and work on performance fixes for the message queue, we feel
this is an acceptable trade-off. Furthermore, almost nobody uses inproc
for anything, and even fewer people are making use of the statistics
at this time.

We also have made some support changes, including new APIs for printing
URLs, and some improvements to the NNG_OPT_URL to make use of this new
property.

This is a major change, and includes changes to use a polymorphic
stream API for all transports. There have been related bugs fixed
along the way. Additionally the man pages have changed.
The old non-polymorphic APIs are removed now. This is a breaking
change, but the old APIs were never part of any released public API.
