Coinbase signature is not part of the Sv2 protocol, some pool maybe want to use it other not. The first part of the extranonce could also be reserved for things that are not a pool signature. This pr rename the pool_signature field of the channel factory into additional_coinbase_script_data and change the type from Strgin to Vec<u8>, since can be anything.
The coinbase input script additional data should be sent as part of the extranonce_prefix and not as part of the coinbase_prefix. So that a JDC can see what the pool want as coinbase input script additional data without the need to observ the coinbase prefix in job constructed by the pool.
Update the pool to use an extranonce of 16 bytes rather then 32 so that there is enaugh space to add the additional coinbase input script data.
Right now the channel factory only support one active job at time. That means that if we receive a share for a job right after we sent downstream a new job that share will be invalid. Now the channel factory keep track of the last 3 jobs, so we give time to the dowstream to receive the job and propagate it down before stop accepting shares for older job. This is useful, and the system can be more responsive: as soon as we change the coinbase additional input script data we can send a new job dowsntream without worrying of invalidating miner's shares. When the pool receive a prev hash it immidiatly invalidate all the previous jobs, we still want to refuse shares for stale jobs. The client can easly handle this situation: when a pool refuse a share it should start a timer and if do not receive a new prev hash (or already have) within n seconds it change pool.
This commit fix 2 miner things: When we calculate the coinbase_prefix (what we need to put in the extended job) we need to account also for the coinbase input script additional data that is part of the extranonce. When we create pool channel facotry we pass an extranonce creator and an pool signature. If the signature + extranonce are bigger then 32 bytes we have to return an error. That cause in sv2 the extranonce can not be longer than 32 bytes.
The translator normalize the coinbase and remove the segwit data from the coinbase prefix and suffix. In order to do that it need to know the extranonce len, we used a default value of 322 bytes, but the pool could use also smalle extranonces.
Add a method that the pool can use in order to change coinbase_script_additional_data of an already opened channel and send downstream the new extranonce_prefix
Add time buffer to fix signature verification error

Coinbase signature is not part of the Sv2 protocol, some pool maybe want to use it other not. The first part of the extranonce could also be reserved for things that are not a pool signature. This pr rename the pool_signature field of the channel factory into additional_coinbase_script_data and change the type from Strgin to Vec<u8>, since can be anything.
The coinbase input script additional data should be sent as part of the extranonce_prefix and not as part of the coinbase_prefix. So that a JDC can see what the pool want as coinbase input script additional data without the need to observ the coinbase prefix in job constructed by the pool.
Update the pool to use an extranonce of 16 bytes rather then 32 so that there is enaugh space to add the additional coinbase input script data.
Right now the channel factory only support one active job at time. That means that if we receive a share for a job right after we sent downstream a new job that share will be invalid. Now the channel factory keep track of the last 3 jobs, so we give time to the dowstream to receive the job and propagate it down before stop accepting shares for older job. This is useful, and the system can be more responsive: as soon as we change the coinbase additional input script data we can send a new job dowsntream without worrying of invalidating miner's shares. When the pool receive a prev hash it immidiatly invalidate all the previous jobs, we still want to refuse shares for stale jobs. The client can easly handle this situation: when a pool refuse a share it should start a timer and if do not receive a new prev hash (or already have) within n seconds it change pool.
This commit fix 2 miner things: When we calculate the coinbase_prefix (what we need to put in the extended job) we need to account also for the coinbase input script additional data that is part of the extranonce. When we create pool channel facotry we pass an extranonce creator and an pool signature. If the signature + extranonce are bigger then 32 bytes we have to return an error. That cause in sv2 the extranonce can not be longer than 32 bytes.
The translator normalize the coinbase and remove the segwit data from the coinbase prefix and suffix. In order to do that it need to know the extranonce len, we used a default value of 322 bytes, but the pool could use also smalle extranonces.
Add a method that the pool can use in order to change coinbase_script_additional_data of an already opened channel and send downstream the new extranonce_prefix

As per stratum-mining/sv2-spec#99 this PR change the implementation so that in the JD protocol full tx ids are used instead of short tx ids. It also remove the IdentifyTransaction and IdentifyTransactionSuccess messages since are not needed anymore.
it need #1248
