SERVER-15223 Properly handle MemberStates before first heartbeat in TopologyCoordinatorImpl.
SERVER-15089 chooseNewSyncSource hooked up in replication Applier
SERVER-6157 Remove FastArray

It has no remaining users since the old external sorter was removed. Since it
has no advantages over a std::vector, it should never be used again.
SERVER-15111 Treat corruption of final journal section as an expected event
SERVER-13951 Add a WUOW around logOp in applyOps
SERVER-15192 Temporarily disallow rollback of logOp

Since there are currently logOp listeners that are not rollback safe we are
temporarily disallowing rollback of all operations once they get to the
logOp. This will work since (today) we only call logOp once we know an
operation will succeed and commit.
SERVER-13635 Heap allocate the OperationContextImpl for each request

Allocating it on the stack resulted in each request on a connection having the
same OperationContext pointer. This can mask places where we stash the
pointer and use it after the original has be destroyed, because a new one has
been constructed in the same place. Switching to a heap allocation should
minimize this, especially when using the debug allocator.
SERVER-15111 use boost 1.49 compatible copy_file
SERVER-15229 include collection scan or index scan direction in new explain output
SERVER-15089 remove fatal state and refactor rollback to use replcoord
