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:

This adds a limit of 1,000 passes to the payment engine. It protects against
possible cases where the execution of a pass fails to exhaust the liquidity
that made the pass possible or cases where two passes alternate providing
liquidity for each other.
* Compute the effective recipient.

SHAMapTreeNode

1) Truly public.
2) Used only by SHAMap.
3) Truly private to SHAMapTreeNode.
SHAMapItem
* Remove SHAMapItem::pointer and SHAMapItem::ref.
* Add std includes necessary to make the header standalone.
* Remove implementation from the SHAMapItem declaration.
* Make clear what part of SHAMapItem is:
1) Truly public.
2) Used only by SHAMapTreeNode.
3) Truly private to SHAMapItem.
SHAMapSyncFilter

SHAMapNodeID
* Remove unused mHash member.

* Remove unused getCountedObjectName().
* Remove SHAMap::pointer
* Remove SHAMap::ref
* Remove unused fetchPackEntry_t.
* Remove inline member function definitions from class declaration.
* Remove unused getTrustedPath.
* Remove unused getPath.
* Remove unused visitLeavesInternal.
* Make SHAMapState an enum class.
* Explicitly delete SHAMap copy members.
* Reduce access to nested types as much as possible.
* Normalize member data names to one style.
* Change last of the typedefs to usings under shamap.
* Reorder some includes ripple-first, beast-second.
* Declare a few constructions from make_shared with auto.
* Mark those SHAMap member functions which can be, with const.
* Add missing includes
Remove the use of ec_key parameters and return values from ECDSA crypto
prototypes. Don't store key data into an ec_key variable only to fetch
it back into the original type again. Use uint256 and Blob explicitly.
Pass private keys as uint256, and pass public keys as either pointer and
length or Blob in calls to ECDSA{Sign,Verify}() and {en,de}cryptECIES().
Replace GenerateRootDeterministicKey() with separate functions returning
either the public or private key, since no caller needs both at once.
Simplify the use of GenerateDeterministicKey within RippleAddress. Call
a single routine rather than pass the result of one as input to another.
Add openssl unit with RAII classes for bignum, bn_ctx, and ec_point plus
free utility functions.
Rewrite the functions in GenerateDeterministicKey.cpp to use RAII rather
than explicit cleanup code:
* factor out secp256k1_group and secp256k1_order for reuse rather than
computing them each time
* replace getPublicKey() with serialize_ec_point(), which makes, sets,
and destroys an ec_key internally (sparing the caller those details)
and calls i2o_ECPublicKey() directly
* return bignum rather than ec_key from GenerateRootDeterministicKey()
* return ec_point rather than EC_KEY* from GenerateRootPubKey()
Move ECDSA{Private,Public}Key() to a new ECDSAKey unit.
Move ec_key.h into impl/ since it's no longer used outside crypto/.
Remove now-unused member functions from ec_key.
Change tabs to spaces; trim trailing whitespace (including blank lines).
In normal operation, InboundLedgers::findCreate never returns null, but
during system shutdown, it will return null.
Since this only happens in system shutdown, when findCreate returns null
the calling function stops what it was doing and returns.
During testing, an issue where destroying the application object
and creating a new one caused problems with a static PathTable. This table
is now cleared when re-initialized.
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
* Replace SYSTEM_NAME and other macros with C++ constructs
* Remove RIPPLE_ARRAYSIZE and use std::extent or ranged for loops
* Remove old-style, unused offer crossing unit test
* Make STAmount::saFromRate free and remove default argument

is not the source account.
* Restrict to 80-columns and other style cleanups.
