@nuttycom
Use transaction builder for asyncrpcoperation_sendmany.
f9477a4 
This replaces the old implementation of asyncrpcoperation_sendmany
with one where all transaction construction is delegated to the
transaction builder. The capabilities of z_sendmany are somewhat
modified in the process:

* z_sendmany now permits sending funds from a Sprout address to
  both transparent and Sapling addresses. PRIVACY NOTE: When
  user sends a Sprout->Sapling transaction, the amount of the
  transaction is publicly revealed.
* z_sendmany no longer supports transactions sending funds into
  the Sprout pool, with the exception of change amounts when
  sending from a Sprout address.
* When sending transparent coinbase funds to a set of shielded
  addresses, the amount sent to recipients must fully consume
  the input value and no change is permitted. This is a slightly
  weaker constraint than was previously implemented; in the past,
  only a single shielded recipient was allowed.

Require an explicit flag to allow cross-pool transfers in z_sendmany.
9554ed2 
This adds an `allowRevealedAmounts` argument to z_sendmany. This
flag must be present to allow an amount-revealing cross-pool transfer
to be constructed.
