Merged in of async branch:

Major changes:

Alternative "async/external" Processing Model

The SipStack & DUM can now run w/out being in a build/select/process
loop.  This is accomplished witht ransports that provide their own cycles, as well
as an external timer api.  The SipStack is constructed w/ an
AsyncProcessHandler which gets notified when a message is put into the
StateMacFifo, or when SipStack::postMs or SipStack::post is called.  This can be
optimized a bit more; in some cases only a timer adjustment may be required, but
the stack might not require cycles.  DumProcessHandler, located in the Dum
directory, is a example of how to use this.  Note that it provides ares w/ a 50
ms timer when there is an active query.  DnsInterface now has a requiresProcess
method to facilitate this; it should possibly become another
getTimeTillNextProcess method.

Transport Refactoring/Cleanup

TransportSelector now only understands objects that derive from Transport.  The
SipStack is responsible for the Transport Factory behaviour of addTransport.  A
lot of the Transport has moved into InternalTransport, to keep the Transport
abstraction clean.  Also, the tcp transports have been cleaned up; most of dlb's
rant in ConnectionBase.hxx has been answered. 

IpVersion vs Bool IpV4

bool is no longer used to represnt IpVersion, the enum is used in tuple and
anywhere else I spotted it.

The result of this merge/cleanup has been regressed; I still need to re-write
testTransportSelector.cxx.  The async model has not been used yet with the
esult of this merge, but it was sued extensively in the branch.
