32b683bf37 Enable "missing prototypes" warning for gcc, clang
Missing prototypes for exported functions cause a really huge issue on
Windows.  Enabling the "missing prototypes" warning makes it much easier
to catch this problem.  Naturally, any warnings caused by this have been
fixed.

19aec98b8a Clean up return code types
* 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

cd6742ee12 Rearrange and fixup abstraction layer
- 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.
