* improve DHT routing table to return better nodes (lower RTT and closer
to target)
* don't use pointers to resume_data and file_priorities in
add_torrent_params

as taking existing ones
* fix choking issue at high upload rates
* optimized rate limiter
* make disk cache pool allocator configurable
* fix library ABI to not depend on logging being enabled
* use hex encoding instead of base32 in create_magnet_uri
* include name, save_path and torrent_file in torrent_status, for
improved performance
* separate anonymous mode and force-proxy mode, and tighten it up a bit
* add per-tracker scrape information to announce_entry
* report errors in read_piece_alert
* DHT memory optimization
* improve DHT lookup speed
* improve support for windows XP and earlier
* introduce global connection priority for improved swarm performance
* make files deleted alert non-discardable
* make built-in sha functions not conflict with libcrypto
* improve web seed hash failure case
* improve DHT lookup times
* uTP path MTU discovery improvements

with more files

* suppress initial 'completed' announce to trackers added with replace_trackers
after becoming a seed
* SOCKS4 fix for trying to connect over IPv6
* fix saving resume data when removing all trackers
* fix bug in udp_socket when changing socks5 proxy quickly
