name-parser: Revert file name change

[why]
It is better to have a not-abbreviated file name so that one can make
sense out of the name parts, especially when doing a partial patch.
With the previous commit we ended up with all abbreviated names.

The filename length is hopefully not limited, at least not as severe as
the SFNT table entries.

[how]
We need to store the answers somewhere because the naming is only
understood by the FontnameParser object which we throw away soon.
As fallback we still can parse the SFNT table, for example when the old
renaming is used.
