This includes changes to support setting the sanitizer *correctly*
(the old code CMake stuff didn't quite get it right), and addresses
a number of failures in the test code found by the address sanitizer.

This is a significant refactor of the library configuration.
We use the modern package configuration helper, with a template
script that also does the find_package dance for any of our
dependencies.
We also have restructured the code so that most protocols and
transports have their configuration isolated to their own CMakeLists
file, reducing the size of the global CMakeLists file.

fixes #490 posix_epdesc use-after-free bug
fixes #489 Sanitizer based testing would help
fixes #492 Numerous memory leaks found with sanitizer
This introduces support for compiler-based sanitizers when using
clang or gcc (and not on Windows). See NNG_SANITIZER for possible
settings such as "thread" or "address".
Furthermore, we have fixed the issues we found with both the
thread and address sanitizers. We believe that the thread issues
pointed to a low frequency use-after-free responsible for rare
crashes in some of the tests.
The tests generally have their timeouts doubled when running under
a sanitizer, to account for the extra long times that the sanitizer
can cause these to take.
While here, we also changed the compat_ws test to avoid a particularly
painful and time consuming DNS lookup, and we made the nngcat_unlimited
test a bit more robust by waiting before sending traffic.

This introduces a new transport (compatible with the TLS
transport from mangos), using TLS v1.2.
To use the new transport, you must have the mbed TLS library
available on your system (Xenial libmbedtls-dev). You can use
version 2.x or newer -- 1.3.x and PolarSSL versions are not
supported.
You enable the TLS transport with -DNNG_TRANSPORT_TLS=ON in the CMake
configuration.
You must configure the server certificate by default, and this can only
be done using nng options. See the nng_tls man page for details.
This work is experimental, and was made possible by Capitar IT Group BV,
and Staysail Systems, Inc.
