Refactor Ledger and support classes:

Browse Source

This performs a deep refactor on the Ledger class and its supporting
classes, in preparation for the move to shared_ptr<SLE const> in
places where the SLE is immutable and we are currently using
shared_ptr<SLE>.

Member functions are converted to free functions, the SLECache is an
explicit parameter, one line convenience functions are removed to
streamline the interface. Some callers are changed to use <SLE const>
instead of <SLE>

SLECache:
* Moved to its own header file

RippleState:
* Remove unused functions
* Store the SLE as const
* Simplify callers

AccountState:
* Remove unused members
* Simplify existing members

Ledger:
* Replace writeBack with insert and update
* Remove unused functions
* Remove LedgerStateParams
* Move getLastFullLedger to Application
* add entryCacheI, exists, fetch, erase
* Use boost::optional where it makes sense
* Make member functions free functions

Free functions:
* fetch: cache-aware SLE retrieval
* forEachItem, forEachItemAfter
* (various)
