Adds a new --jobs command-line argument to specify how many worker connections you want. These worker connections should stick around while processing table(s) in a single database. For each table, parcel out the indexes to be built among these worker conns, submitting each CREATE INDEX ... request using PQsendQuery() i.e. in non-blocking fashion. Most of this is still rather crude, in particular the while (num_active_workers) ... loop in rebuild_indexes(), but it seems to be working, so I'm committing here.
