[jacodb-core] Add de-duplication of attribute values in AttributesImmutable As of this commit, values array contains only different attribute values. [jacodb-core] Close ers iff it was initialized [jacodb-core] Processed only jar files referenced in the Class-Path attribute of manifest [jacodb-storage] Fix minor memory usage issue in AttributesImmutable Avoid using class constructor parameters in lazy fields. [jacodb-storage] Reduce memory usage by InstanceIdCollections In this commit, two implementation of InstanceIdCollection added, SortedIntArrayInstanceIdCollection & UnsortedIntArrayInstanceIdCollection. If instances ids of particular attributes cannot be packed in a LongRange, but if they all can be represented as an Int, then corresponding implementations wrap IntArray, not LongArray. [jacodb-storage] Minor: toAttributesImmutable() is an extension for list of attribute pairs [jacodb-storage] Optimize AttributesImmutable.navigate() in case of sorted by value attributes If attributes are sorted by value, in binary search algorithm, getting instance id by index of an attribute value can be skipped. In that case, copying of the attribute value in an extra byte array is redundant, and comparing can be done by a special comparison function. [jacodb-storage] Re-order built-in bindings [jacodb-storage] Optimize dealing with instance ids in AttributesImmutable Instead of LongArray, instance ids are represented by implementors of InstanceIdCollection. LongRangeInstanceIdCollection saves memory by using LongRange instead of LongArray. The getByIndex() method introduced and used where possible in order to skip conversion of instance id to index in InstanceIdCollection to load values from values byte array. [jacodb-benchmarks] Make RAMEntityRelationshipStorageBenchmarks more correct Fewer operations on each invocation, this reduces Java GC load. [jacodb-storage] Optimize PropertiesMutable.getEntitiesLtValue() & PropertiesMutable.getEntitiesEqOrLtValue() Minor optimization: exit iteration over value index earlier. This is okay since all further values are greater than specified one. [jacodb-benchmarks] Add benchmarks of RAM implementation of ERS API [jacodb-storage] Get rid of using one-nio library ByteArrayBuilder added instead of one-nio's one. SparseBitSet moved to the 'org.jacodb.util.collections' package.
