Play nice with further customizations of eldoc-message-function

Browse Source 
Uses a :before-until advice on the local value of
eldoc-message-function instead of setting it directly.  Thus, when we
give up because of eldoc-box-only-multi-line (or some other future
criteria), other :before-until handlers can kick in.

* eldoc-box.el (eldoc-box--eldoc-message-function): Control return of
t or nil.
(eldoc-box-hover-mode): Use add-function and
remove-function.
