It is an excellent platform for catching bugs: big-endian, slow enough
that a context switch in the middle of an operation becomes a regular
occurrence, and all that on a SMP box. Or: I just wanted to see if it
would work.

Code formatting was quite a mess (different indentation, completely
different ideas on where opening braces should go, spacing in various
places, early out versus single return or goto-based error handling,
&c.). This commit cleans it up.
A few doxygen comment fixes allowed turning on Clang's warnings for
doxygen comments, so those are no enabled by default as least on
Xcode-based builds.

* Remove dds_return_t / dds_retcode_t distinction (now there is only
dds_return_t and all error codes are always negative)
* Remove Q_ERR_... error codes and replace them by DDS_RETCODE_...
ones so that there is only one set of error codes
* Replace a whole bunch "int" return types that were used to return
Q_ERR_... codes by "dds_return_t" return types

As was the plan with the introduction of ddsrt; this includes renaming
the identifiers to match the capitalization style and removes old junk.

- 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.
