* 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.

This will eliminate two large dependencies when building CycloneDDS with
colcon for ROS 2, which doesn't appear to need the IDLC.

This is useful when building CycloneDDS on platforms that provide CMake
configuration for CUnit outside of Conan.
If no configuration is found in the system CMake registry the module
continues as before.

These conditionals may fail if the variable they're checking isn't
defined at all. Adding quotes makes the comparison against an empty
string in this case, which avoids the syntax error.

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.

Test is constructed to have the events trigger only at the appropriate
times, but it does assume that the store to cb_called becomes visible
prior to the listener callback. I'm pretty sure that will always be
the case in practice, but I'm also pretty sure there is no formal
guarantee without a memory barrier, which mutex_unlock provides.

Initialisation of ddsrt layer uses a hand-rolled CAS/sleep device not
unlike a spin lock. This so initialisation doesn't depend on, e.g.,
ddsrt_once.
Checking or changing thread states between "awake" and "asleep" can end
up in ddsrt_init if the thread is unknown at the time of the call.
Once really only ends up in those cases when the library is initialised
already, in which case no sleeping occurs.
In any case, the sleep is just a friendly yielding of the CPU. Coverity
will still see the loop, just not the sleep.

In the case of when a DATA_ON_READERS listener is set, but with the
corresponding status mask is set to suppress the event, the reader lock
would not be in locked, resulting in a unlocked access of status flags
and a double unlock.

For targets that do not support ddsrt_setenv and ddsrt_getenv, an alternative
method is needed to supply an application specific configuration. One way to
implement this, is to add a function for creating a domain with a string
arguments, which needs to be called before any call to dds_create_participant
for given domain identifier.
The function dds_create_domain has been added, which has as arguments a domain
identifier and a configuration string. The string is treated in the same way
as the string that is retrieved from the environment variable, in that it may
containt a comma separated list of file names and/or XML fragments for the
configuration.
Two tests have been added. One limits the number of participants to two and
verifies that creating a third participant fails. The other tests checks
incorrect calls to dds_create_domain.
An assert in dds_handle_delete has been weakened.

Those fail with a small probability, but it is still annoying. The code
has been vetted and tested; and by disabling the test only when run in
the CI infrastructure, anyone changing the code would still have the
test run locally.

Rare intermittent failure appears to be timing. Increasing the timeout

Deleting participant does: add to "deleted participants", remove from
