Released v2.3.0

• Fixed: (BUG::old) fc4c_hash32(): unaligned bytes at the end of hashed area were not used for hash value computation. Container header version changed from 1.4 to 2.0, old saved containers are automatically converted to new version. Unfortunately, this breaks saved hash tables which were generated using old version of fc4c_hash32(), so the old version is now exported as fc4c_hash32_1_x().
• Fixed: (BUG) drb_Push(DRB_DYNAMIC): could fail due to optimized insertion at the end of buffer.
• Change: dar_Alloc(): do not sum requested number of items with prefetch value: always use prefetch, unless the requested number is higher.
• Change: drb_GetItem() returns newly added items only, that is items which were not de-queued with drb_Get()
• Added: drb_GetLastItem(): equivalent to drb_GetItem(drb_t*, drb_GetCount()-1).
• Added: drb_IsEmpty() returns true if there are no items left for drb_Get()
