block_log_util changes

This MR remakes tool block_log_util, list of changes:

• removing positional options, everything has to be specified explicitly,
• all logs are in one file, specified by -l option, tool output returns only result or error,
• get-block returns additionally block_id and signing_key,
• added get version option, which returns git revision and info for which type of network this tool was built
• get-block-ids, get-block-artifacts, get-block options accepts both block number and blocks range, negative numbers support was introduced (details can be see in tool's help)
• get-block has output option which allows to dump all requested blocks into separate files

In addition to the above tool changes, the following changes have also been introduced:

• file lock on block_log and block_log.artifacts files, when opening them.
• fixed bugs in file appender - unified log to be similar to console logs + fixed problem when we wanted to create log file where there is no parent directory.
• compression dictionaries are now also used for testnet build.
