improve how MTQs interact with the terms dict cache
---------------------------------------------------

                 Key: LUCENE-2674
                 URL: https://issues.apache.org/jira/browse/LUCENE-2674
             Project: Lucene - Java
          Issue Type: Improvement
          Components: Index
            Reporter: Michael McCandless
            Assignee: Michael McCandless
             Fix For: 4.0
         Attachments: LUCENE-2674.patch

Some small improvements:

  * Adds a TermsEnum.cacheCurrentTerm "hint" (codec can make this a no-op)

  * Removes the FTE.useTermsCache

  * Changes MTQ's TermCollector API to accept the TermsEnum so collectors can eg call .docFreq
directly

  * Adds expert ctor to TermQuery allowing you to pass in the docFreq
