* refactor: add a Mediator class to decouple tr_session and tr_port_forwarding
* refactor: add tr_port_forwarding::Mediator::privatePeerPort()
* refactor: add tr_port_forwarding::Mediator::onPortForwarded()
* chore: avoid unnecessary include of timer.h in other headers
* refactor: use a uniform timerMaker() API in mediators
Add a shim between the handshake code and the rest of the codebase to
improve decoupling so that a followup PR can add handshake unit tests.
The handshake code no longer directly relies on tr_torrent, tr_session,
tr_dht, or tr_peerMgr.
* 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.
* refactor: make tr_peerIo a class
No behavioral changes.
Use `new` and `delete` and change `struct` references to `class`.
* refactor: make some tr_peerIo fields const
* refactor: reorganize tr_peerIo fields to remove padding holes
* refactor: remove redundant field tr_peerIo.isIncoming
* refactor: make tr_peerIo.inbuf, .outbuf fields const*
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.
The Berne Convention says that the copyright year is moot, so instead of adding another year to each file as in previous years, I've removed the year altogether from the source code comments in libtransmission, gtk, qt, utils, daemon, and cli.
Juliusz's copyright notice in tr-dht and Johannes' copyright notice in tr-lpd have been left alone; it didn't seem appropriate to modify them.
