LUCENE-1713, LUCENE-1673: For completeness, add some getter methods to TermRangeFilter, to be similar like TermRangeQuery and NumericRangeFilter.

This also unifies the hashCode and equals methods in this family of queries. It also fixes a bug in hashCode and equals of NumericRangeQuery, missing the constantScoreRewrite property.
TermRangeTermEnum was changed to have a consistent ctor with TermRangeQuery.
