Previously, having everything in a single file causes issues, because
build.py is also called from CMake to get the version number. This only
worked for users, who had "requests" installed, as this library is
required in build.py.
The reuse linter only supports single files inside the LICENSE folder.
As the HTML version for the license is only required for the installer,
this commit moves it to the installer folder.
Nowadays most of the loadbalancing is done on the server-side and hence
there is only a single datafile URL (and other URLs) inside the
boostrap.json.
The features of the CUrlList are hence not really used. This is also a
step into removing CUrl and using QUrl instead, to avoid maintaining a
separate URL class.
With default settings, FSUIPC was not really used
by FS simulators (except FS9) as the transponder
mode readout was done with SB offsets through SimConnect.
For simplification, this removes FSUIPC from fscommon and moves it to FS9.
Therefor this also removes the option for FSX/P3D users to toggle FSUIPC.
The watchdog was used in a few places as a shortcut to skip reading
data. Further, it was used in some places in the UI to display
connectivity. But it also introduced quite some complexity. In some
cases it can be fragile: network accessibilty cannot be looked up on all
platforms/hardware constellations. The connectivity could change
between the last watchdog call and the real call. Hence all readers must
still handle the case where the connection fails.
To simplify swift and further reduce the dependency onto the project
infrastructure (pings etc.), this removes the watchdog.
This also removes the QNetworkConfigurationManager, which is deprecated
and not available with Qt6.
Previous we relyed on the watchdog providing a working shared URL (or
empty URL if no URL was reachable). This creates some overhead and
might not work in all cases because of the time between the call to
getWorkingSharedUrl() and the actual network request. Further, not all
calls that are fetching data from our servers were using the shared URL
from the watchdog anyway.
Lastly, this careful checking if the URL is available is only done for
the shared URL and not for all the other URLs that are queried by swift.
