* M6: flattening removes empty fields it cannot draw (#4017)

Flattening kept every widget without an appearance so that its value
was not lost with nothing drawn in its place (#1794). A field without a
value has nothing to lose, yet it stayed in /AcroForm /Fields and on the
page, so a flattened file could still be filled in.

A widget without an appearance now stays only when its field has a
value: its /V, or the nearest one inherited through /Parent. A missing
value, an empty string or an empty array is no value. Comments and
valued widgets are unchanged.

Fixes #4017

* M6: flattening keeps a widget whose value is past the parent limit (#4017)

has_value walks at most 64 levels up /Parent. When it ran out it said
"no value", so a widget whose /V sat on the 64th ancestor was removed.
Running out now counts as a value: one that wasn't checked must not be
removed.
