Improved signature verification for TON L2 networks

The appearance of new networks in which a user can reuse the same key for the same contracts carries new risks. The proposed solution allows using same keys and contracts across different L2 networks without worrying about new replay attacks, as the signatures themselves will be different everywhere and will depend on a unique network ID (later referred to as global_id).

Most contracts verify the signature of external message with CHKSIGNU or CHKSIGNS. Therefore, to minimize the number of any changes, we propose adding new behavior for these opcodes (enabled/disabled via capability). Fow now, this new behavior can only be implemented on the L2 side, however, it requires at least the reservation of three additional opcodes, which are needed for explicit verification of signatures with other ids.

Tutorial collect contract gas metric

PR: ton-community/ton-docs#1294

When writing contracts for the TON blockchain, it's important to consider how efficiently gas is consumed when executing the logic you implement, in addition, unlike other blockchains, in the TON blockchain you need to pay for storing contract data and for forward messages between contracts

Therefore, when developing a contract, it's important to pay attention to how data size changes and how gas consumption changes after you modify the contract's behavior or add new functionality
