This commits adds support for the DOMAIN_ID and DOMAIN_TAG parameters in
participant discovery, allowing multiple domains to share a port
number (a feature introduced in DDSI 2.3). The tag can be configured
via Discovery/Tag.
This commit also introduces a setting Discovery/ExternalDomainId that
makes it possible to override the domain id on the network, both in what
is advertised in the DOMAIN_ID discovery parameter and in the
calculation of port numbers. This way a single process can create two
independent domains that talk via the network, which is on occassion
useful in writing tests.

Connext (sometimes, for some versions?) sends a pre-emptive ACKNACK with
a base sequence number of 0, which were rejected following the DDSI
specification (8.3.4.1, 8.3.5.5 and 8.3.7.1.3). That doesn't really
help anyone. (https://github.com/ros2/ros2/issues/824)

Installing Cyclone DDS for multiple architectures with the same
installation prefix gave problems because the CMake configuration files
ended up overwriting each other. This brings it in line with the
recommended locations. Thanks to @hansfn.

This allows you to express a dependency on it as `find_package(CycloneDDS REQUIRED COMPONENTS idlc)`
Also added a warning if CycloneDDS was built with IDLC but IDLC is not requested.

This adds two things to the XSD (and the RNC file and options.md):
* attributes previously missing because of a bug in the conversion
script
* a name space (https://cdds.io/config)
Adding the name spacing requires a different set of attributes at the
top of a configuration file, which in turn need to be ignored by the
configuration parser, and which should be reflected in the configuration
example in the README.

Sign extension causes some character values to be interpreted as special
tokens, potentially causing the parser to hang, pass a null pointer as
element name to the "elem_open" callback (which would crash the
configuration processing).

When scanning buckets while looking for a specific element, it is faster
to only inspect those buckets for which the corresponding bit in
"hopinfo" is set. Sadly, simple scanning is faster than the far more
elegant perfect hash based on a De Bruijn sequence.
Add a simple test/performance measurement.

* Moved bswap functions to ddsrt
Moved the byte swapping functions from ddsi to ddsrt so that
these can be re-used in e.g. the security plugins and tests.

CMAKE_PROJECT_NAME refers to the top-level project name, not the most recent project. So any CMake project that pulls this in as a dependency was in for a nasty surprise.

The test only works on Linux and macOS because of the system
dependencies in catching an abort. The logging code is platform
independent so testing only on these platforms still gives a good sanity
check.

Allow unique prefix matches for elements and attributes specified in
directly in CYCLONEDDS_URI. That mode already has a few niceties for
quickly specifying some configuration overrides, this is simply one
more.

The ``docs/makernc.pl`` perl script can extract the options from the
source code for the configuration processing and turn these into a
GitHub MarkDown document and a RELAX NG Compact form (RNC) description
of the options. Standard conversion tools can be used to turn the RNC
file into an XSD.
Although they are generated by a mechanical transformation, it is not
(yet) part of the build process, in no small part because there no
proper generation and publishing system has yet been set up for the
documentation.
Now that there is an XSD and a Markdown file for discovering the
options, there is no need to retain the configuration editing tool. Any
decent editor will do a better job.

From a distant past came code to encrypt data on the wire, but it hasn't
been functional in Cyclone for a long time and it only ever provided
protection against casual eavesdroppers. It is better to delete it.

* macOS < 10.13: skip log tests for want of fmemopen
There is a dependency on fmemopen in the tests for the logging
functions, which macOS introduced only in version 10.13. There should
be no other obstacle to building/running/testing on older versions of
macOS. This commit does the pragmatic thing: remove the dependency and
turns the tests into no-ops in this one case.
