* Move the project top-level CMakeLists.txt to the root of the project;
this allows building Cyclone as part of ROS2 without any special
tricks;
* Clean up the build options:
ENABLE_SSL: whether to check for and include OpenSSL support if a
library can be found (default = ON); this used to be
called DDSC_ENABLE_OPENSSL, the old name is deprecated
but still works
BUILD_DOCS: whether to build docs (default = OFF)
BUILD_TESTING: whether to build test (default = OFF)
* Collect all documentation into top-level "docs" directory;
* Move the examples to the top-level directory;
* Remove the unused and somewhat misleading pseudo-default
cyclonedds.xml;
* Remove unused cmake files

The CMake files now add "-Werror"/"/WX" if the "WERROR" CMake variable
is true. By default it is not; the CI builds set this.

Getting cmake to work with/without conan on macOS, Linux and Windows
seems to be trickier than it should be when dealing with older cmake
versions. Switching to an Ubuntu Xenial image on Travis CI at least
makes it build again.
The update then also eliminates the need to update cmake, clang and
maven, saving quite a bit of build time. A few small tweaks and an
update to the macOS image version reduces some 5 minutes from the macOS
build time.
The minimum required version for cmake needs to be updated, too, but
really only when openssl support is included. So instead of raising the
required version in the CMakeFile I am in favour of simply hoping for
the best.
