Within AchievementManager, CloseGame being called when LoadGame fails was causing m_queue.Cancel to be called within a lock when Cancel itself locks until it is empty, causing a deadlock. This is resolved by cancelling the queues outside of the lock when they are safe to wait for resolutions.
A new class that derives from `QMenu` has been introduced. Menus of this
`NonAutodismissibleMenu` type will stay visible when a _checkable_
action is triggered.
This is convenient in menus that feature a series of check boxes that
toggle visibility of third components (e.g. the **List Columns** menu),
allowing the user to toggle several actions at once.
For now, the new type is used in the top menu bar.
Verify a touchpad is present before polling it for input. Without this
check the Debug log is spammed with the message "error: Parameter
'touchpad' is invalid" if you have a controller without a touchpad.
One would think every touchpad supports at least 1 finger, but in case
there's some weird edge case check the finger count to be sure.
This fixes a memory leak that would occur when the Android frontend
calls LogManager::Init more than once in order to reload settings.
Note that the log window listener is now owned by LogManager instead of
by the frontend, making it consistent with the other log listeners.
Old cruft from when the Android code was loading INI files manually.
We don't have any handling for failing to load settings anymore.
This change also updates related comments to reflect how things actually
work nowadays.
