* refactor: add tr_torrent_metainfo class
Can be used for parsing bencoded .torrent data without instantiating
a tr_torrent. This will be used in all the places where client code
needs to test a .torrent file for validity / to add a preview window
before adding the torrent.
* refactor: encapsulate request tracking in a class
Introduces a new class to peer-mgr, `ClientRequests`, which tracks what
active requests we've got pending: which blocks, when the requests were
sent, and who they were sent to.
This shouldn't change peer-mgr behavior. Its goal is to carve out some
of peer-mgr's data structures and encapsulte them behind an API that's
simpler to understand.
* refactor: move ActiveRequests to its own file
* perf: avoid duplicate call to tr_cpMissingBlocksInPiece
* perf: don't update queue positions during shutdown
When a torrent is being removed, we try to update the queue positions of
the other torrents. But it's (slightly) expensive and is irrelevant when
the session is closing, so skip it in that case.
* perf: torrentLoadResume shouldn't touch tor->dirty
Loading torrent settings from disk does call a lot of tr_torrentSetFoo()
functions, but since these are the saved settings, they shouldnt' affect
the torrent's 'is dirty' flag.
* refactor: [[maybe_unused]] iff arg _might_ be used
If the arg is never used, comment out its name.
If the arg is _sometimes_ used e.g. with ifdefs, use [[maybe_unused]].
* 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: s/tr_torrentFiles/tr_torrentFileProgress
Replace tr_torrentFiles() with a new function, tr_torrentFileProgress().
tr_torrentFiles() heap-allocated an array of progress structs. There is
nothing intrinsic in tr_torrent making batch computation more efficient,
so this PR replaces it with tr_torrentFileProgress(), a per-file variant
that doesn't use the heap.
* refactor: add an enumeration of the script types
This simplifies the API by having a single set of functions that can be
used for getting/setting all the script types.
* chore: allow vararg calls in qt/.clang-tidy
An awkward PR since this isn't intended for the qt/ codebase at all, but
rather for use with libtransmission instead. But libtransmission is *so*
noncompilant at this point that this config can't be promoted higher up
the tree yet. Instead, it needs to be callable on-request by devs.

this field now points to tr_torrent.errorString instead of copying into
a standalone char array.
old: sizeof(tr_torrent) 2640
new: sizeof(tr_torrent) 2136

Port libtransmission to C++. This PR doesn't refactor everything to c++.
Its code changes are only what was necessary to compile and link as c++.
See libtransmission/README.md for details on how to submit modernization
patches!
