* fixup! refactor: tr_webseed simplification (#2613)
call connection_limiter.taskStarted in the right place
* perf: put web thread to sleep when inactive
* refactor: reduce nested conditional webseed logic
* refactor: use tr_block_info::Location in webseed
* request larger chunks at a time from webseeds
* fix: CURLOPT_MAXREDIRS to safeguard against loops
Discussion at https://trac.transmissionbt.com/ticket/6110 .
Reported by @x190 and @cfpp2p a few years back.
* refactor: add fetch options object to tr_webRun()
Fold `tr_webRun()`, `tr_webRunWithCookies()`, and `tr_webRunWebseed()`
into a single API that takes an options argument that callers can
customize to their needs.
Also does a surface cleanup pass to the tr_webseed and tr_web internal
structures, e.g. making fields const where possible, not using raw
pointers, and making some fields private.
This revision is still full of code smells. Refactoring the entire
system is overwhelming, so instead I'm doing it in incremental steps.
* refactor: remove effective-url caching in webseeds
The upcoming CURLSH refactor is a more effective way of doing this and
the current appoach makes tr_web harder to refactor, so remove it.
* refactor: webseed rate limiting
The current code that limits the number of parallel fetches is overly
complicated and is also interwoven into the tr_webseed class. Extract
it into a new private helper class "ConnectionLimiter" with a simpler
public API for tr_webseed to use.
* refactor: include <memory> when using shared_ptr or unique_ptr
* refactor: include <cstdio> iff we use it
* refactor: include <cstring> iff we use it
* refactor: include <cstdlib> iff we use it
* refactor: include <string_view> or <string> iff we use it
* refactor: include <array> iff we use it
* refactor: include <ctime> iff we use it
* refactor: include <cctype> iff we use it
* refactor: misc #include cleanups in libtransmission
* 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
* 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]].

* 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.
