This implements the tracking of when an amendment achieved a majority
in the ledger, ensuring that there's always network-wide agreement
on which amendments have achieved a majority and how long they've
held it.
* New fields
* Change transactor changes
* AmendmentTable API and implementation changes
* Update amendment enabled status on validated ledgers
* Reinstate support for ledger sequence in fee transactions
* This silences a warning about a redundant cv-qualifier.
* This makes future coding mistakes about redundant
cv-qualifiers much less likely.
* This makes the code easier to read.
This introduces the STVar container, capable of holding any STBase-derived
class and implementing a "small string" optimization. STObject is changed
to store std::vector<STVar> instead of boost::ptr_vector<STBase>. This
eliminates a significant number of needless dynamic memory allocations and
deallocations during transaction processing when ledger entries are
deserialized. It comes at the expense of larger overall storage requirements
for STObject.
* Remove unused members
* SerialIter holds only a pointer and offset now
* Use free functions for some Serializer members
* Use SerialIter in some places instead of Serializer
