a11c4bbd26 Exempt unspendable transaction outputs from dust checks 
Since unspendable outputs can't be spent, there is no threshold at which it would be uneconomic to spend them.

This primarily targets transaction outputs with `OP_RETURN`.

07e6d5b025 Refactor GetTxid() into UpdateTxid() to match coding style of hash member variable. 
UpdateTxid() is called alongside UpdateHash() when a CTransaction is

1e84d84d3a Rename GetHash() method to GetSerializeHash(). 
When pulling from upstream we are now forced to examine GetHash() usage
and replace with GetSerializeHash() if the caller wants a double SHA256
hash, or with GetTxid() if the caller wants a transaction id.
