e1a3461cc2 Improve/Fix variable names 
ZCProof was too general. pubKeyHash was actually the JoinSplit pubkey
itself.

9e5398686c Auto merge of #3206 - bitcartel:3194_polymorphic_note_class, r=str4d 
Update note classes to be polymorphic

Closes #3194.  Lays foundation for introduction of Sapling notes through refactoring and creation of a class hierarchy for Sprout notes.  This PR updates some tests, but otherwise is a no-op.

bf605b2644 Return result of boost::apply_visitor 
Not returning a value at the end of a non-void function is undefined behaviour.
Given that this managed to pass our full test suite, I guess that GCC looks for
un-returned values at the end of a function and uses them as the return value,
if the keyword is missing. Clang OTOH complains, which is how we spotted this:

Details of Sapling datatypes will be filled in later; for now, they are treated
as binary blobs.

38276c6ba2 Add GenIdentity, an identity function for MappedShuffle. 
We use this function in z_sendmany as part of the fix for #1779.

7c463780cf Fixes #1779 so that sending to multiple zaddrs no longer fails. 
Commit 2eeb6b randomized the order of input and output notes,
but this is now known to prevent the chaining of multiple joinsplits
in a single transaction.  The root cause has yet to be determined.

This patch is a temporary fix and disables the shuffling of input
and output notes.  It also adds a chained joinsplit test to the
python qa test suite.

07e6d5b025 Refactor GetTxid() into UpdateTxid() to match coding style of hash member variable. 
UpdateTxid() is called alongside UpdateHash() when a CTransaction is
deserialized or constructed.  GetTxid() now returns a const reference.

1e84d84d3a Rename GetHash() method to GetSerializeHash(). 
When pulling from upstream we are now forced to examine GetHash() usage

hash, or with GetTxid() if the caller wants a transaction id.
