Username ce2d28ab07 httpd: cache sqlite connections per-greenlet, lazy-load ASN, sharpen URL scoring ...

- threading.local() caches proxy_db and url_db per greenlet (eliminates
  ~2.7k redundant sqlite3.connect + PRAGMA calls per session on odin)
- ASN database now lazy-loaded on first lookup (defers ~3.6s startup cost)
- URL claim error penalty increased from 0.3*error(cap 2) to 0.5*error(cap 4)
  and stale penalty from 0.1*stale(cap 1) to 0.2*stale(cap 1.5) to reduce
  worker cycles wasted on erroring URLs (71% of 7,158 URLs erroring)
