Bridge new methods

[marcos-iov]

Description

New public methods added to brdige, only for queries

Motivation and Context

Implements RSK220

The activation is Iris

The methods are
getBtcBlockchainBestBlockHeader()
getBtcBlockchainBlockHeaderByHash(hash)
getBtcBlockchainBlockHeaderByHeight(height)
getBtcBlockchainParentBlockHeaderByHash(hash)

How Has This Been Tested?

Code tests were added for new methods in Bridge and BridgeSupport

A manuel test:

Install npm install rskclitools -g

In a working folder, execute

rskcli sethost mainnet
rskcli newaccount alice
rskcli execute bridge.js

where bridge.js is

async function execute(context, args) {
    console.log('get best block number');
    const best = await context.command('call').execute([ 'alice', '0x01000006', 'getBtcBlockchainBestChainHeight()' ], { verbose: true });
    console.log('get best block header');
    await context.command('call').execute([ 'alice', '0x01000006', 'getBtcBlockchainBestBlockHeader()', 'bytes' ], { verbose: true });
    const hash = '0x0000000000000000004ac5d97713216c1162bdfe1bc30862990c550a1994c5a7';
    console.log('get block header by hash');
    await context.command('call').execute([ 'alice', '0x01000006', 'getBtcBlockchainBlockHeaderByHash(bytes32)', hash,  'bytes' ], { verbose: true });
    console.log('get parent block header by hash');
    await context.command('call').execute([ 'alice', '0x01000006', 'getBtcBlockchainParentBlockHeaderByHash(bytes32)', hash,  'bytes' ], { verbose: true });
    console.log('get block header by height');
    await context.command('call').execute([ 'alice', '0x01000006', 'getBtcBlockchainBlockHeaderByHeight(uint256)', best - 1,  'bytes' ], { verbose: true });
};

module.exports = execute;
