fontselect: don't trim font names

This matches the behavior of GDI and hence VSFilter.

Note that \fn arguments are trimmed during parsing.
However, none of the names inside fonts should be trimmed,
and @-prefixed fonts should keep whitespace following the @,
both of which this commit addresses.

Remove strdup_trimmed because it is no longer used. Also remove
the declaration of a function that was deleted a few months ago.
