The nodelist_idx for each node_t serves as a unique identifier for the node, so we can use a bitarray to hold all the excluded nodes, and then remove them from the smartlist. Previously use used smartlist_subtract(sl, excluded), which is O(len(sl)*len(excluded)). We can use this function in other places too, but this is the one that showed up on the profiles of 30291. Closes ticket 30307.
