USBDevicePicker: Modify USBDeviceAddToWhitelistDialog to be more generic, and use it for a new "More Options..." selection in Bluetooth Passthrough adapters
Show "(off)" instead of "" when the default post-processing effect is
selected. This also indirectly fixes issues with keyboard navigation of
the post-processing effect combobox when the default is selected,
resolving https://bugs.dolphin-emu.org/issues/13863.
m_post_processing_effect was previously using the ConfigStringChoice
constructor that assumes the text and data of each option are identical.
This is true for all the other effects, but since "(off)" has the config
value of "" this assumption was failing for it, causing the combobox to
be blank.
Keep the BalloonTip open when the BalloonTip's arrow prevents the cursor
from being inside the spawning ToolTipWidget, which triggers the
ToolTipWidget's leaveEvent and would previously close the BalloonTip.
When that happens track the cursor until it either leaves the
ToolTipWidget's bounding box or leaves the BalloonTip and goes back to
the ToolTipWidget, and respectively close the BalloonTip or leave it
open.
Use ToolTipWidget::SetDescription insead of QWidget::setTooltip to put
the description in the BalloonTip with the title, instead of having the
description be in a separate standard tooltip.
Separate LibUSB logic into LibUSBBluetoothAdapter class.
Submit transfers on thread with proper timing.
Throttle before ACL input for reduced input latency.
Immediately send IPC replies for outgoing data.
Continuously submit libusb transfers to fill HCI/ACL input queues.
Simplify endpoint handling and state saving.
Other cleanups.
Remove window hints clearing the flag Qt::WindowContextHelpButtonHint,
which is already off by default in Qt 6.
In Qt 5 this flag was set by default for QDialogs, and on Windows put a
? button in the corner of the title bar allowing users to activate Qt's
QWhatsThis help system for a given widget. Since we don't set that text
the ? button was useless and so we hid it manually.
Fix the UI hanging for several seconds when opening the Controllers
window.
Move the scan for Bluetooth adapters onto a separate thread so the Host
thread doesn't have to wait for it.
Only automatically scan for adapters once, when opening the Controllers
window for the first time. Add a Refresh button to let the user refresh
the adapter list afterward.
