Add an "Advanced Settings" option to the gpodder sign in. If selected, a fully
qualified URL must be specified as the gpodder base. Upon successful login, the
URL is saved along with username and password. If advanced settings are not
selected, an empty URL is stored and the default will be used.
It's not necessary for the PodcastSettingsPage class to have knowledge of
GPodderSync's login implementation. Handling the network reply in a single
location sightly simplifies the code. It also makes the handling order
more deterministic.
A closure created by NewClosure that handles Qt signals is destroyed if the
signal object is destroyed, the slot object is destroyed, or the signal is
invoked. In the case where the sender is passed as a shared pointer, the
reference prevents the sender from being destroyed before the closure.
So for closures built to handle responses returned from ApiRequest in
GPodderSync, the closure object and the response object will only be destroyed
after the signal is invoked. In some cases, separate closures are built for
error signals as well. For these, only one closure will be destroyed. The other
closures and the response object will be leaked.
A simple fix for the success cases is to remove the unnecessary error case
closures and directly connect the signals to slots. This is low hanging fruit
and still leaves leaks in the error cases. Those cases will require a more
complete solution to properly manage the life cycle of the response object.
