added a config file parser
added tracker id
changed WANT_CLOSED_TRACKER and WANT_BLACKLIST into WANT_ACCESS_WHITE and WANT_ACCESS_BLACK
changed WANT_TRACKER_SYNC to WANT_SYNC_BATCH and added WANT_SYNC_LIVE
added an option to switch off fullscrapes

cleaned up many internal hardcoded values, like PROTO_FLAG,

1. stats for added and removed torrents
2. stats for start and stopped events from peers

this should help to detect DoS attacks and is useful for
profiling

Drop ot_{byte,word,dword} and use uint{8,16,32}_t, also move run time keeping and FULLSCRAPE stderr output to ot_stats

No one can get access to buckets now without locking them. Also split up the trackerlogic.c-monster in functional sub-units. HEADS UP: this code is untested and not considered stable.
