c5419f9487 revise discoverInterfaces() 
change interface to distingush between bcast and point2point.
add netmask to truly distinguish unicast from bcast.
fix some minor (I think) errors in the bsd socks impl (use of clobbered buffer).
cleanup win32 impl. bcast and p2p handling.

4baa72c91d avoid data race 
destroy() sets _serverSocketChannel=INVALID_SOCKET under the lock.
Other changes are made before the worker thread starts.

4b3237a20d BlockingUDPTransport::enqueueSendRequest cleanup? 
oh my was this bad code!  It isn't clear what
lock()/unlock() are guarding, but let them
continue as before, but don't swallow any exception,
or unlock twice.

d424202323 client: exception propagation from callbacks 
Swallowing exceptions here hides some of our errors.
Particularly unrecoverable introspectionRegistry misses.
Instead, propagate up to Thread and close connection.

fe5780521b Context::getSecurityPlugins() no return of non-const ref. 
Return of map as non-const ref. allows callers to modify.
Probably unintended.

df14a19ae0 codec: eliminate internalPostClose()

da85d39c0c codec: const-ify socket 
Avoid possible data race of changing _channel
before worker threads are joined.
Was just using this as a boolean flag for a method
which is already guarded in BlockingTCPTransportCodec::close()
from being called twice.

735dc22e2d collapse SimpleChannelSearchManagerImpl into ChannelSearchManager

1a100a0955 client fix init order leading to *NULL 
Avoid a race between the main thread alloc of SimpleChannelSearchManagerImpl
the the UDP socket worker trying to use the same.

Split allocation and initialization of search manager
around socket creation and worker start.

Also in-line initializeUDPTransport() to only call site.

a10534d74d eliminate Connector interface 
no code generically creates UDP or TCP connections,
so this abstraction results only in unnecessary
virtual calls and casts.

0161799c93 must zero osiSockAddr prior to use! 
RTEMS depends on this or eg. bind()
will fail because comparison with
list of interface addresses is done
with memcmp()!
