* refactor: move handshake_done args into a convenience struct
* refactor: move peer_id from peerIo to tr_handshake
tr_handshake is a short-term object and tr_peerIo is long-term, so this
effectively narrows the scope of this field.
* chore: remove unused field tr_peerIo.isEncrypted
* refactor: add tr_peer_id_t type to hold peer ids.
this is a 'using' alias to a std::array<> so that code passing peer-ids
around doesn't have to memcmp / memcpy PEER_ID_LEN anymore. Also removes
the now-unused PEER_ID_LEN macro.
* perf: prioritize announces based on scrape stats
This change is to improve responsiveness when starting a large batch of
torrents, e.g. when starting up a seedbox, but is also generally useful.
First, try to scrape as many torrents as as quickly as possible, giving
preference to that even over announces. Thanks to multiscrape we can run
through scrapes an order of magnitude faster than announces. Then scrape
responses tell us which swarms have leechers and we can prioritize those
torrents' announces.
Second, increase how many scrapes and announces we start at a time. This
limit probably hasn't been needed since 2da97b25 and by scraping faster,
the sooner we'll know which torrents to announce first.
* chore: remove printf() tracer
* feat: make multiscrape limits adaptive
Previously hardcoded by TR_MULTISCRAPE_MAX. This change makes
that the initial value, then incrementally lowers the value
when multiscrapes get "req too long" style errors.
* fix: don't log personal announce url
* chore: treat HTTP 400 as scrape-too-long
* chore: copyediting
* chore: copyediting
* move 'const' to the right of the type
* make conditional tests explicitly boolean
* make 'key' const
* don't lookup a value we already have
* make an array for known too-big scrape error messages
* improved multiscrape throttle logging
* fix: multiscraping of low numbers of torrents
Handle the case of getting a 'multiscrape too big' error message
back even if the user fewer than TR_MULTISCRAPE_MAX torrents.
* uncrustify
* fix oops
* refactor: remove TR_MULTISCRAPE_MIN
Is there any reason to have a minimum batch size?

This way all the qualifiers (`const`, `volatile`, `mutable`) are grouped
together, e.g. `T const* const x` vs. `const T* const x`. Also helps reading
types right-to-left, e.g. "constant pointer to constant T" vs. "constant
pointer to T which is constant".
There're places where manual intervention is still required as uncrustify
is not ideal (unfortunately), but at least one may rely on it to do the
right thing most of the time (e.g. when sending in a patch).
The style itself is quite different from what we had before but making it
uniform across all the codebase is the key. I also hope that it'll make the
code more readable (YMMV) and less sensitive to further changes.
1. add the option the code to be used under GPLv2 or GPLv3; previously only GPLv2 was allowed
2. add the "proxy option" as described in GPLv3 so we can add future licenses without having to bulk-edit everything again :)
3. remove the awkward "exception for MIT code in Mac client" clause; it was unnecessary and confusing.
This is a little overlapping since the utp code can be closed more-or-less immediately, but the udp manager needs to stay open in order to process the udp tracker connection requests before sending out event=stopped. Moreover DNS resolver can be shut down after the UDP tracker is shutdown.
