Abhishek Kona	2ba866e0c5	GetSequence API in write batch. Summary: WriteBatch is now used by the GetUpdatesSinceAPI. This API is external and will be used by the rocks server. Rocks Server and others will need to know about the Sequence Number in the WriteBatch. This public method will allow for that. Test Plan: make all check.

Abhishek Kona	8055008909	GetUpdatesSince API to enable replication. Summary: How it works: * GetUpdatesSince takes a SequenceNumber. * A LogFile with the first SequenceNumber nearest and lesser than the requested Sequence Number is found. * Seek in the logFile till the requested SeqNumber is found. * Return an iterator which contains logic to return record's one by one. Test Plan: * Test case included to check the good code path. * Will update with more test-cases. * Feedback required on test-cases.

Fix a number of object lifetime/ownership issues

Summary:
Replace manual memory management with std::unique_ptr in a
number of places; not exhaustive, but this fixes a few leaks with file
handles as well as clarifies semantics of the ownership of file handles
with log classes.

Test Plan: db_stress, make check

GetSequence API in write batch.

Summary:
WriteBatch is now used by the GetUpdatesSinceAPI. This API is external
and will be used by the rocks server. Rocks Server and others will need
to know about the Sequence Number in the WriteBatch. This public method
will allow for that.

Test Plan: make all check.
