This changes the code to make use of a different project we have
created (libzerotiercore) that is "CMake clean". This should make
using and configuring this code *much* better. It may also have the
benefit of making this configuration work better for Windows systems.

This reverts 707, and provides a correct fix for busted
port discrimination. It also has a few minor cleanups
and reduces the listen timeout to 10 seconds.

Both the man page and the comment (in nng.h) of nng_send()
say that the buffer is freed only if the function succeeds.
The previous code always freed (if the flag was set). This
change only frees if we succeed.

The fix for #715 to address const is still not quite right.
In ISO C, the argv array is just char **. getopt() in POSIX uses
char *const[]. That part is right, but we should then not pass
const char ** in calls. Furthermore, really the optarg should also
not be constified.
This aligns us closer to getopt() and leads to the fewest problems.
This does represent a slight breaking change, but as old code should
still compile and run, we don't think we should bump the API version
for this change. Furthermore, we don't think anyone else is actually
using this API yet.

This introduces new public APIs for obtaining statistics,
and adds some generic stats for dialers, listeners, pipes, and
sockets. Also added are stats for inproc and pairv1 protocol.
The other protocols and transports will have stats added
incrementally as time goes on.
A simple test program, and man pages are provided for this.
Start by looking at nng_stat(5).
Statistics does have some impact, and they can be disabled by
using the advanced NNG_ENABLE_STATS (setting it to OFF, it's
ON by default) if you need to build a minimized configuration.

We use macros to generate message bodies for each of the various
variants, reducing source code size (but not compiled size). The
documentation is updated to indicate each of these variants.

While here we separate out the dialer and listener options, so
that options for tuning connection are only available for listeners.

This adds a couple of new methods, and related documentation
and test cases.

Basically, we can ignore EV_EOF, as we wind up still alerting
the corresponding events. EV_ERROR we still treat as HUP.
(The EV_EOF was responsible for prematurely closing the socket
and aborting transactions while there was still data in the socket
buffers.)

This both makes new functions available to the core,
and addresses a bug which would have prevented building the
ZeroTier transport on Windows.

This also fixes a leaked TCP connection on a failure path, which we
noticed while working this change.

Well, actually, #506 fixed that, but this fixes the commentary
that indicates otherwise in the code.

This changes the signature of the aio cancellation routines
to take the argument for cancellation directly, so we do not
need to lookup the argument using the nni_aio_get_prov_data.
We should probably consider eliminating nni_aio_get_prov_data,
and co, and changing the prov_extra to reflect prov_data. Later.

The POLLHUP (or rather EPOLLHUP) flag does not quite mean the same
thing in Linux, and we've seen random failures where we will sometimes
get this event on a socket that is freshly connected. This might be
a bug in Linux, but it is easy enough to workaround -- we just don't
watch for it at all.

Actually the problem was in socket core, in particular in the
shutdown code. The socket shutdown is supposed to ensure that
no pipes were present on the socket, so that protocols need not
concern themselves with this. The code unfortunately was busted,
due to an ordering problem compounded by a race condition. This
fixes that, and changes the REQ protocol to avoid the blocking
condition altogether, and sprinkles a few assertions to validate
these rules are being adhered to.

fixes #599 nng_dial sync should not return until added to socket
This reintroduces the changes for the above fixes, building upon the
transport modifications that we have made to eliminate the separate
transport pipe start entry point. It also includes slightly reworked
code during start to put a hold on the pipe when it is created, which
we we drop at the end, hopefully fixing a use-after-free.

While here, perform a more aggressive close of the pipe on
reaping (IPC).
