Description
This PR simplifies the logic by doing the checks regarding availability of slots in the Add() function of the OverflowPool rather than before where this logic was outside.
This also addressed an edge case where if the OverflowPool is full, we simply take out one transaction and put the new one in. But this might result in the pool size exceeding its limit because the new transaction might have more slots than the older transaction.
Also fix the bug: we were comparing number of transactions with number of slots here:
if uint64(len(tp.txHeap)) >= tp.maxSizeSlots should be compared with slots.
Added TestTxOverflowPoolSlotCalculation() to capture the bug in the previous code.
The current change ensures we never exceed the set total size of the overflow pool.
