This PR should reduce overall allocations of a running node by ~10
percent. Since most allocations are coming from the re-heaping of the
transaction pool.

It also speeds up the process by ~60%
There are two minor caveats with this PR:
- We change the API for `EffectiveGasTipCmp` and `EffectiveGasTipIntCmp`
(which are probably not used by much)
- We slightly change the behavior of `tx.EffectiveGasTip` when it
returns an error. It would previously return a negative number on error,
now it does not (since uint256 does not allow for negative numbers)
