The 'SSL torrent' feature is not standardized. I.e. there are no BEP (BitTorrent Enhancement Proposals) associated with it, so we do not greatly encourage its usage as it will only work with libtorrent clients and derivatives. It will not work with other torrent clients that do not support the libtorrent specific implementation.
This PR aims to provide minimal support for those who need SSL torrents. Furthermore, it is intended that there will be no UI support (nor indication) of adding/creating SSL torrents.
* Prerequisites:
I omit the instructions of creating those files as the intended audience (experts & advanced users) should have no problem with it. All files are as follow:
1. Root (torrent publisher) certificate
2. Root private key
3. A .torrent file created with root certificate
5. Peer certificate (signed by the root certificate)
6. Peer private key
7. Diffie-Hellman parameters file
All files are stored in .pem format.
* Enable SSL torrent protocol in qbt
There are 2 hidden keys to put in qbt config file, under `[BitTorrent]` section:
1. `Session\SSL\Enabled`: set it to `true`.
2. `Session\SSL\Port`: set it to some unused port or omit the key entirely to let qbt pick one for you.
* Add an SSL torrent to qbt
The only way of adding an SSL torrent is via WebAPI. The `/api/v2/torrents/add` endpoint will support 3 additional parameters. You must provide them for an SSL torrent.
1. `ssl_certificate`: Contents of the peer certificate file (in PEM format).
2. `ssl_private_key`: Contents of the peer private key file.
3. `ssl_dh_params`: Contents of the Diffie-Hellman parameters file.
* Change the SSL parameters to a torrent
In case you provided wrong SSL parameters when adding a torrent, there is a new endpoint `/api/v2/torrents/setSSLParameters` that you can update the SSL parameters. The parameters (`ssl_*`) are the same as `/api/v2/torrents/add` endpoint.
* Query the SSL parameters of a torrent
There is a new endpoint `/api/v2/torrents/SSLParameters` that you can query the SSL parameters of a torrent.

1. Use proper case folding function instead of `toLower()`.
2. Use locale aware comparison instead of comparing unicode code points.
Now `a` comes before `A` which is the same as the result from QCollator. A nice side effect
is now it properly compares locale specific characters (for example `C`, `Č`).
3. Improve testing. Now the test is runnable and stable on all platforms.

According to https://doc.qt.io/qt-6/qcollator.html#posix-fallback-implementation
The 'POSIX fallback implementation' is only used when ICU is not available. So the correct way is to detect ICU directly and not depend on the OS. The exceptions are macOS and Windows since they support the required functionalities natively.

* Use correct pointer type in NSIS scripts
* Only remove qbt specific registry keys when uninstalling or disassociating
* Set .torrent Content Type when associating .torrent format
* Move ".torrent association" functions to Utils::OS class

* Add torrent entry status to represent tracker error
* Add torrent entry status to represent unreachable endpoint
* Display tracker entry next/min announce time
* Reset tracker entries when torrent is stopped
Warning: users are at their own discretion to create .torrent with >= 64 MiB piece size as not
every torrent client supports it.
Larger piece sizes are only available when using libtorrent 2.x. libtorrent 1.x is not
efficient with memory usage and in order to avoid user complaints it is limited to 128 MiB.
Also note that, as of this writing, libtorrent 2.0.9 has an internal limitation that only
allows loading maximum 256 MiB piece size. And therefore > 256 MiB size options are forbidden
for now.
Closes#19527.
PR #19535.
It now guards against reading infinite files such as `/dev/zero`.
And most readings are bound with a (lax) limit.
As a side effect, more checking are done when reading a file and
overall the reading procedure is more robust.
