Dynamically resize line number gutter width (#3469)

* dynamically resize line number gutter width

* removing digits lower-bound, permitting spacer

* removing max line num char limit; adding notes; qualified successors; notes

* updating tests to use new line number width when testing views

* linenr width based on document line count

* using min width of 2 so line numbers relative is useful

* lint rolling; removing unnecessary type parameter lifetime

* merge change resolution

* reformat code

* rename row_styler to style; add int_log resource

* adding spacer to gutters default; updating book config entry

* adding view.inner_height(), swap for loop for iterator

* reverting change of current! to view! now that doc is not needed
