* Fix "sgn" in fift; fix marking infinite loops as noterurn in func
* TON-P1-1: Remove unused catchain queries
* TON-P1-15: Avoid synchronization with self
* TON-P1-3, TON-P1-17: Disallow more than one candidate per src per round (to prevent flood), add checks to process_broadcast
* TON-P1-10: Fix fast/slow attempts
* TON-P1-14: Add named constants
* TON-P1-18, TON-P1-19: Alloc temporary memory in the same way as persistent memory
* TON-P1-20: Add comment to choose_blocks_to_approve
* TON-P1-16: Avoid creating two catchain blocks on need_new_block
* TON-P1-8: Add some validation to validator-engine parameters
* TON-P1-6: Don't allow sending the same block many times
Many requests for the same block are not unusual (however, there's no need to answer them all)
* TON-P1-2: Enable prohibiting dependencies from blamed nodes (2.7.5 in CatChain doc), fix processing blame proofs
* Best practices
bp-6: Fix incorrect warning
bp-7: Remove unused code
bp-8: Bring back PerfWarningTimer logging (only when no callback)
bp-9: Remove unnecessary condition
bp-11: Remove commented-out code
bp-13: Divide code in validator-session-state
Adherence to Specification: Fix typo
- added some fift scripts for the config change proposal voting
- added validator-engine-console support for the config change proposal voting
- additional sanity checks in catchain
- unsafe slow catchain resync method
updated tonlib
fixed bugs in func
validator: partial support for hardforks
liteserver: support for waitMasterchainBlock prefix
transactions: support for gas flat rate
1. Updated block header, proofs now contain more data
Notice, that old proofs may become invalid in the future
2. Fixed message routing
3. Fixed block creator id in block header
4. Support for full proofs in tonlib
5. Support for partial state download
6. Some other bugfixes
1. update liteclient/liteserver. Now liteserver sends signatures of
blocks and liteclient checks them. I.e. liteclient completely checks
received data.
2. validator-engine: more GC options
3. blockchain-explorer: show all block transactions (instead of 256)
4. some bugfixes
