* 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

- Replace os_result by dds_retcode_t and move DDS return code defines down.
Eliminates the need to convert between different return code types.
- Move dds_time_t down and remove os_time.
Eliminates the need to convert between different time representations and
reduces code duplication.
- Remove use of Microsoft source-code annotation language (SAL).
SAL annotations are Microsoft specific and not very well documented. This
makes it very difficult for contributers to write.
- Rearrange the abstraction layer to be feature-based. The previous layout
falsely assumed that the operating system dictates which implementation is
best suited. For general purpose operating systems this is mostly true, but
embedded targets require a slightly different approach and may not even offer
all features. The new layout makes it possible to mix-and-match feature
implementations and allows for features to not be implemented at all.
- Replace the os prefix by ddsrt to avoid name collisions.
- Remove various portions of unused and unwanted code.
- Export thread names on all supported platforms.
- Return native thread identifier on POSIX compatible platforms.
- Add timed wait for condition variables that takes an absolute time.
- Remove system abstraction for errno. The os_getErrno and os_setErrno were
incorrect. Functions that might fail now simply return a DDS return code
instead.
- Remove thread-specific memory abstraction. os_threadMemGet and accompanying
functions were a mess and their use has been eliminated by other changes in
this commit.
- Replace attribute (re)defines by ddsrt_ prefixed equivalents to avoid name
collisions and problems with faulty __nonnull__ attributes.
