Revert of deletion of Mike's first comment (sorry)

Patch against 3.x.

I moved the to/from byte[] methods from Solr's TrieField into Lucene's 
NumericUtils, and fixed FieldsWriter/Reader to use free bits in the field's 
flags to know if the field is Numeric, and which type.

I added a random test case to verify we now get the right NumericField back, 
when we stored NumericField during indexing.

Old indices are handled fine (you'll get a String-ified Field back like you did 
before).

Spookily, nothing failed in Solr... I assume there's somewhere in Solr that 
must now be fixed to handle the fact that a field can come back as 
NumericField?  Anyone know where...?)

> (Spinoff of LUCENE-3001)
> Today when writing stored fields we don't record that the field was a 
> NumericField, and so at IndexReader time you get back an "ordinary" Field and 
> your number has turned into a string.  See 
> https://issues.apache.org/jira/browse/LUCENE-1701?focusedCommentId=12721972&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-12721972
> We have spare bits already in stored fields, so, we should use one to record 
> that the field is numeric, and then encode the numeric field in Solr's 
> more-compact binary format.
> A nice side-effect is we fix the long standing issue that you don't get a 
> NumericField back when loading your document.
