wsock32.lib is only needed for the legacy version of Winsock and is not needed with Winsock2 (the current version).
This appears to be a root cause of the multicast issue on Win10 and may allow us to reverse #404

This commit changes the implementation of topics so that multiple topic
entities can exist in a single participant for the same topic.
Different entities may refer to different topic implementations
(sertopics, akin to a type support in the DDS specification). All
entities (for the same participant) always have the same QoS, via the
new "ktopic" table in the participant.
Readers and writers are bound to a topic entity and inherit its
properties. If a topic comes in two definitions, say one for C and one
for C++, one can have a single participant with a reader delivering the
data in C representation and another reader delivering it in C++
representation.
This changes the behaviour of create_topic and find_topic: these now (on
successful return) always return a new entity (and thus with a unique
handle), where previously these would simply return a existing one when
possible.
This also requires some small additions to the sertopic/serdata
interface.

* 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.

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.
