- 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.

Make function names more consistent:
* ``dds_topic_{get,set}_filter`` -> ``dds_{get,set}_topic_filter``
* ``dds_{get,set}_enabled_status`` -> ``dds_{get,set}_status_mask``
* ``dds_instance_lookup`` -> ``dds_lookup_instance``
Plus removal of defunct ddsv2.h.
The main naming scheme is OPER_TYPE (i.e., dds_create_participant) but the listener operations were named TYPE_OPER (i.e., dds_listener_create). This commit brings the listener scheme in line with the rest, retaining the old names as a deprecated interface.

Automatic batching is not yet implemented but: it dramatically enhances performance in throughput tests, and enabling it in the config breaks manual publication of data in pubsub. For the time being, it makes more sense to enable manual batching programmatically and force the data out when needed.
