Fixed an off-by-one error in mailbox size handling.
...
The List.put(ref List) overload previously didn't increment m_count for rhs.m_front itself, leading to an underflow of m_count when removing all the messages. I suppose this didn't surface so far because m_count isn't really relevant if no mailbox size limit is set.
Also, I renamed the private put() method to appendNode() to avoid confusion as it is not really an overload semantically.

receive() now works even if thisTid() has never been called within the main thread. also applied use of Duration throughout the receiveTimeout code, since core.sync uses Duration as its native time representation internally as well.

Issue 4307 - spawn()'ed thread doesn't terminate

Changed thisTid to construct a MessageBox if one doesn't exist (true for the main thread and threads created with core.thread instead of spawn). This eliminates a double construction for spawned threads or the alternative of a segfault when sending to a thread not created by spawn.

Changed PriorityMessageException to hold a variant instead of being a template class. This is required to support priority messages received from another process, and also sidesteps a number of implementation issues with the old approach as well. The drawback is that TDPL describes prioritySend as working the old way. This change had to happen at some point however, and better now than later. Next will be to add functionality to PriorityMessageException to simplify introspection and extraction of the message contained.
...
Greatly simplified the code in places and tuned somewhat for performance as well. Normal send/receive is about 25% faster now, and prioritySend is 200 times faster (yes, 20,000%).
Added a unittest or two and verified that they still pass :-p

Fixed an issue where priority messages were being added to both the priority and the standard message queues. This improves performance by an order of magnitude or more, but still leaves priority messaging substantially slower than normal messaging. Looking for more issues.

Eliminated use of ".field" for Tuple field access now that it's no longer necessary.
...
Fixed the occlusion detection for receive() so that functions returning a value (assumed to be bool) do not occlude following functions accepting the same parameter list.
Changed the handling of an OwnerTerminated message so that the OwnerTerminated exception will be thrown immediately on receipt instead of delaying the throw until a receive() is issued where the receive must block and wait for a new message to arrive. Since message arrival is indeterminate (ie. network latency and other factors affect how long it will take for a message to arrive), there was no provable difference between the existing guarantee and the much simpler guarantee that OwnerTerminated is not thrown until all messages have been received from the owner only. Although the early actor model didn't even require messages from a specific sender to arrive in order, experience has shown this guarantee to be too weak for practical use in many scenarios (it's equivalent to having a weak memory model in a SMP system). So std.concurrency will guarantee that all messages from a particular sender will arrive in order and thus the OwnerTerminated message will necessarily be the last message received from the receiver's owner, so when this message is encountered an OwnerTerminated exception will be thrown immediately.
Slightly changed the handling of LinkTerminated vs. OwnerTerminated messages so that an OwnerTerminated exception will always be thrown if the sender is the recipient's owner, regardless of any existing links between the processes. The link is broken if it exists though.

Bug report from Hans Fugal. The callback occlusion detection was borked for receive() and receiveTimeout(). It was failing if the final parameter was a Variant both because of an off-by-1 error and because the test should have been in a "static if" instead of just an "if" block. Unit tests forthcoming.

Made Tid exempt from hasLocalAliasing tests until shared can properly be applied to the mbox field inside Tid. The actual implementation is safe as-is so adding the shared label is mostly to conform to the D2 way of doing things.

Changed spawnLinked so the owner relationship is preserved. The thread link takes precedence when one of the linked threads terminates, but if the link is broken (via the not yet implemented unlink() routine) then an OwnerTerminated exception will still be thrown when the owner terminates.

Added spawnLinked as an experimental feature to test bidirectional linking. A spawnLinked thread won't have an owner, but if either it or the calling process terminates a LinkTerminated exception will be thrown from receive() when called by the other. Another difference is that this exception will be thrown once message list processing has passed through enough of the queue to encounter it rather than when no valid matches were found in the queue and the caller would have to block. I'd like to change the OwnerTerminated mechanism to work the same way (ie. throw when the message is encountered rather than continue scanning the queue looking for valid messages) but this warrants further discussion.
