If compressed and uncompressed blocks arrive at same time, node would sometimes push both. Improve performance by skipping 2nd push

database_api::get_version return type changed to mutable_variant_object (even it still returns same fields as previously), since its response can be extended by optional `haf_revision` entry, providing a HAF version embedding Hived project

Implemented common function: hive::utilities::build_version_info to encapsulate generation of version description.

Hive Utilities CMake processing, detects both revisions: the one specific to the root project and second specific to Hive project directly. This allows to properly report version of Hived in embedded environment (i.e. HAF)

Blockchain worker thread pool during processing takes into consideration status of `is_interrupt_request`.

xxd tool (package) is required to build hived. Also update setup_ubuntu.sh script to include this package in required dependencies.

pow2_evaluator should allow pow-work blocks to be equal to the last irreversible block. That can happen during hived node restart which rollbacks all reversible blocks, and next continue to p2p sync
