Problem statement: user sees its email address in email notification,
while it is better to have sender field app-personalized, like it did
in Nextcloud: they send notifications from user's email address and
add alias 'Nextcloud' to it.
This patch adds alias 'qBittorrent' to qBittorrent email notifications,
so user sees more user-friendly email notification.

1. Initialize Logger class earlier so that it can record messages from other classes (for
debugging purpose).
2. Deprioritize WebUI port adjustment. It is not a high priority in here.
3. Slightly deprioritize file logger initialization.
This is observed by unusual high page faults when the stuttering occurs.
With this workaround, the high page faults still occurs but the GUI remains responsive.
Reduce the total startup time of the application and maintain sufficient responsiveness of the UI during startup due to the following:
1. Load resume data from disk asynchronously in separate thread;
2. Split handling of loaded resume data in chunks;
3. Reduce the number of emitting signals.

The goal is to improve responsiveness of qbt when CPU resources are scarce.
Instead of lowering libtorrent threads priority, it is chosen to raise main event loop thread
priority to avoid getting messy with libtorrent internals.
Also on Windows, threads doesn't inherit thread priority from the parent thread and it always
use the default (normal) priority.
PR #17278.
You can already control the cache size in libtorrent 1.2.x so it doesn't make sense to implement this limit for all use cases. Also there are some downsides to using working set size to limit memory usage such as unresponsive GUI when limit gets hit.

Some linux distros seem to alter TMPDIR environment variable and
therefore hamper qbt ability to find the lock files. So use config
folder instead of TMPDIR folder to create/locate the lock files.
Note that this change will also make qbt become one instance per-user
instead of one instance per-system.
Closes#15646.
Now the comparison function/class should be constructed before usage.
This change also make it easier to plug in into various containers which
will require a compare function type (such as std::set).
Define "torrent ID" concept, which is either a SHA1 hash for torrents of version 1,
or a SHA256 hash (truncated to SHA1 hash length) for torrents of version 2.
Add support for native libtorrent2 info hashes.
