While here, remove some code paths that do not occur by definition.
(For example, if the resolver succeeds, we will definitely have a
valid set of addresses, but if it fails, we will definitely not.)

This avoids the need to perform multiple allocations for dialing,
eliminating additional potential failures. Cancellation is also
made simpler and more perfectly robust.

While TCP and UDP port numbers are 16-bits, ZT uses a larger (24-bit)
port number.

The idea here is to reduce the dynamic allocations used for
URLs, and also the back and forth with parsing begin strings
and port numbers. We always resolve to a port number, and
this is easier for everyone.
The real goal in the long term is to eliminate dynamic allocation
of the URL fields altogether, but that requires a little more
work. This is a step in the right direction.

Applications must now call nng_init(), but they can supply
a set of parameters optionally. The code is now safe for
multiple libraries to do this concurrently, meaning nng_fini
no longer can race against another instance starting up.
The nni_init checks on all public APIs are removed now.

This also checks if the build system has the definitions for AF_INET6, which might
help in some embedded IPv4 only settings.
The resolver test is enhanced to include a check for IPv6 enabled in the kernel.
IPv6 support is enabled by default, of course.

This is based on testutil/acutest, but is cleaner and fixes some
short-comings. We will be adding more support for additional
common paradigms to better facilitate transport tests.
While here we added some more test cases, and fixed a possible
symbol collision in the the stats framework (due to Linux use
of a macro definition of "si_value" in a standard OS header).
Test coverage may regress slightly as we are no longer using
some of the legacy APIs.

There are a few major areas in this change.
* CMake options are now located in a common cmake/NNGOptions.cmake
file. This should make it easier for folks to figure out what
the options are, and how they are used.
* Tests are now scoped with their directory name, which should
avoid possible name collisions with test names.
* A number of tests have been either moved or incorporated into
the newer testutil/acutest framework. We are moving away from
my old c-convey framework to something easier to debug.
* We use CMake directories a bit more extensively leading to a much
cleaner CMake structure. It's not complete, but a big step in the
right direction, and a preview of future work.
* Tests are now run with verbose flags, so we get more test results
in the CI/CD logs.
