How to bring up the addon list interface?

The frame you're after is simply called AddonList. The game opens it by calling ShowUIPanel(AddonList). Be aware that calling ShowUIPanel() causes protected actions that will be blocked while in combat. You may get around this by calling AddonList:Show() directly, but it bypasses UIParent's window management code, which may cause issues with other managed windows.
