1. SOLR-114: HashDocSet specific implementations of union() and andNot()
for a 20x performance improvement for those set operations, and a new
hash algorithm speeds up exists() by 10% and intersectionSize() by 8%.

2. SOLR-115: Solr now uses BooleanQuery.clauses() instead of
BooleanQuery.getClauses() in any situation where there is no risk of
modifying the original query.

Bug Fixes
1. SOLR-87: Parsing of synonym files did not correctly handle escaped
