replace dictionary with hashmap to support null keys
Replace Dictionary with HashMap for tracking SegmentsToMerge in the
IndexWriter. Lucene is using HashMap, and I can confirm by running Lucene 4.8
tests that sometimes there are cases when IndexWriter will insert null value as
key. It is happening here:
https://github.com/apache/lucene-solr/blob/lucene_solr_4_8_0/lucene/core/src/java/org/apache/lucene/index/IndexWriter.java#L1788
When instance of OneMerge is created and passed around there is no
guarantee that segment info will be set.
This now passes TestAddIndexesWithThreads and TestAddIndexesWithRollback in
Lucene.Net.Index.TestAddIndexes.
