First cut at pruning things/updating things.

Remove a bunch of code that Google stopped using/maintaining rather than trying
to update it it. Some would be hard to update, some actually has system provided
replacements; others are patterns that just don't seem as common now.

Prune out the code related to macOS <= 10.5, start pruning some of the really
old iOS support also.

Get the projects mostly limping again with modern Xcodes so tests can be run.

If someone ends up on this commit via history for something they still find
as useful, feel free to do a pull request to bring the snippet of code back to
life and update it for current SDKs.

-// Hack workaround suggested by DTS for the DO deadlock bug.  Basically, this
-// class intercepts the delegate role for DO's receive port (which is an
-// NSMachPort).  When -handlePortMessage: is called, it verifies that the send
-// and receive ports are not nil, then forwards the message on to the original
-// delegate.  If the ports are nil, then the resulting NSConnection would
-// eventually cause us to deadlock.  In this case, it simply ignores the
-// message.  This is only need on Tiger.
