* Support PreviousTxnID until the switchover
* Implement "No Ripple" for issue_iou and redeem_iou.
* Do not utilize issue_iou and redeem_iou from legacy code
* Rename 0.27.x legacy files to account for VS build process
* Misc. cleanups
Certain checks that determine if a transaction is malformed can be performed
without needing to look up accounts or access the ledger.
Perform those checks as early as possible to optimize transaction processing.
Changes made to support autobridging and improve the offer-crossing and
pathfinding logic result in transaction-breaking changes which cause
incompatibilities between 0.27 and 0.28 builds of RippleD.
This patch simplifies deployment of 0.28 on the Ripple network by allowing
RippleD to emulate the 0.27 semantics while the last closed ledger closed
before March 30, 2015 at 13:00:00 PDT, after which time the new 0.28
semantics will become active.
The transaction-breaking changes addressed in this commit are:

Autobridging uses XRP as a natural bridge currency to allow IOU-to-IOU orders
to be satisfied not only from the direct IOU-to-IOU books but also over the
combined IOU-to-XRP and XRP-to-IOU books.
This commit addresses the following issues:
* RIPD-486: Refactoring the taker into a unit-testable architecture
* RIPD-659: Asset-aware offer crossing
* RIPD-491: Unit tests for IOU to XRP, XRP to IOU and IOU to IOU
* RIPD-441: Handle case when autobridging over same owner offers
* RIPD-665: Handle case when autobridging over own offers
* RIPD-273: Groom order books while crossing
An alternative to the unity build, the classic build compiles each
translation unit individually. This adds more modules to the classic build:
* Remove unity header app.h
* Add missing includes as needed
* Remove obsolete NodeStore backend code
* Add app/, core/, crypto/, json/, net/, overlay/, peerfinder/ to classic build
Source files are moved between modules, includes changed and added,
and some code rewritten, with the goal of reducing cross-module dependencies
and eliminating cycles in the dependency graph of classes.
* Remove RippleAddress dependency in CKey_test
* ByteOrder.h, Blob.h, and strHex.h are moved to basics/. This makes
the basics/ module fully independent of other ripple sources.
* types/ is merged into protocol/. The protocol module now contains
all primitive types specific to the Ripple protocol.
* Move ErrorCodes to protocol/
* Move base_uint to basics/
* Move Base58 to crypto/
* Remove dependence on Serializer in GenerateDeterministicKey
* Eliminate unity header json.h
* Remove obsolete unity headers
* Remove unnecessary includes
