Speed increase on startup in presence of many RelTypes

On bulk RelType import that happens on startup, instead of using the
 COW map and insert one by one, store all derived data in local Maps
 and addAll() those to the COW in one operation. Equally thread safe
 and much faster.
Populate indexes even for UPDATE SchemaRule.

Work around for broken SchemaIndexHaIT; index was not being created on slaves.
Needs review with TL.
Write created flag to transaction log for SchemaRuleCommands.

Write an explicit byte indicating whether or not the schema rule was created.

The created flag on the DynamicRecord is not serialised through any other mechanism,
which was causing inconsistent behaviour whenever the commands we being executed
after deserialisation.

This approach differs from the RecordChanges approach used with other commands;
it seemed unnecessary to serialise the previous state of the records when all we need
is an additional flag.
