components: Allow cancelling of dialog between prompts

Browse Source 
Some callers of the keyring prompt keep the dialog up while
processing the prompt. Allow the user to cancel the prompt
while in this state.

This is propagated to the caller, who can cancel the operation
in question when this occurs.
