Fix potential deadlock if the code inside timer callbacks publishes property updates
Thread::Join() is now public.

This is specifically to support TcpSession::Terminate(), but I beleive this
is ok more generally: If a code has a handle to another thread, I don't see
any good reason why it shouldn't be allowed to Join() that thread.
Add SocketTcpSession::Terminate()

This is called by SocketTcpServer::~SocketTcpServer(), per each
SocketTcpSession, immediately *before* calling the SocketTcpSession's
virtual dtor. This guarantees that the session thread has exited
before we destroy the session.

This synchronisation is currently done in extensive per-subclass
boilerplate: We should be able to remove that code now.
Updated to iOS 6.1 sdk
Fix port no. logging in SocketUdpMulticast ctor.
Add some tests to SuiteEndpoint
Remove definitions of debug levels not used by ohNet.  Mark which levels are available for use by client code (the kApplication ones).  Avoiding clashing uses of app values is left as an exercise for client code.
Added functions for appending 16-bit and 32-bit values to a buffer using current platform endianness.
Added buffer append functions for TInt16 and TInt32
Changed value comparison in TestBuffer for Append(<int_type>) functions to avoid strict-aliasing warnings
Replaced value comparison in TestBuffer for Append(<int_type>) tests with memcmp
Rename Ascii::AppendHex() -> Ascii::AppendHexTrim().

Ascii::AppendHex() is now an implementation that does /not/
trim leading zeros.
Return correct number of characters from Ascii::AppendHex( ... , TUint)
Fix tests to accomodate change to Ascii::AppendHex()
Change Srx::Peek to return less content then requested at the end of a stream (it previously threw)
Fix resource leaks in Java bindings
Remove XML for a service we don't generate proxies or providers for and which doesn't exist on any devices
Fix dodgy casting that caused different values to be returned for true on big and little endian builds
Ensure property change callbacks to run immediately a client-initiated resubscribe completes
Add coverage for untested Hex functions in Ascii.
