This replaces the previously hardcoded "numberOfAdditionalBatchesToSearch" variable, and specifies the minimum number of empty consecutive addresses required before a set of wallet transactions is considered complete. Used for foreign transaction lists and balances.
This is a simple way to discard the 5-minute online account timestamps (from out of date nodes) once the switch to 30-minute online account timestamps has taken place.
Although BlockMinter could reattach a repository session to its cache of potential blocks,
and these blocks would in turn reattach that repository session to their transactions,
further transaction-specific fields (e.g. creator PublicKeyAccount) were not being updated.
This would lead to NPEs like the following:
Exception in thread "BlockMinter" java.lang.NullPointerException

where the Account has an associated repository session which is now obsolete.
This commit reverts BlockMinter back to obtaining a repository session before entering main loop.
To prevent a single or very small number of minters receiving the rewards for an entire tier, share bins can now require "activation". This adds the requirement that a minimum number of accounts must be present in a share bin before it is considered active. When inactive, the rewards and minters are added to the previous tier.
Summary of new functionality:
- If a share bin has more than one, but less than 30 accounts present, the rewards and accounts are shifted to the previous share bin.
- This process is iterative, so the accounts can shift through multiple tiers until the minimum number of accounts is met, OR the share bin's starting level is less than shareBinActivationMinLevel.
- Applies to level 7+, so that no backwards support is needed. It will only take effect once the first account reaches level 7.
This requires hot swapping the sharesByLevel data to combine tiers where needed, so is a considerable shift away from the immutable array that was in place previously.
All existing and new unit tests are now passing, however a lot more testing will be needed.
Online account credit is a more useful definition of "minting" than block signing, from the user's perspective. Should bring UI minting/syncing status in line with the core's systray status.
- Reduce concurrent reward share limit from 6 to 3 (or from 5 to 2 when including self share) - as per community vote.
- Founders remain at 6 (5 when including self share) - also decided in community vote.
- When all slots are being filled, require that at least one is a self share, so that not all can be used for sponsorship.
- Activates at future undecided timestamp.
