Refining handling of primitive types
3c0997f 
Fixed bug TagValueConversions.toBoolean
Could cause LegacyTagMap.EntryReader to produce incorrect answers to some queries

For simplicity, now treating Byte and Short as Integer.  That will make calling code doing primitive handling simpler.

Fleshing out tests -- more tests to come

Direct TagMap.Entry support in AgentSpan / DDSpan
9d43d47 
Adding methods to AgentSpan / DDSpan that take TagMap.Entry/Reader objects directly

This will enable TagMap.Entry reuse which can reduce memory allocation/GC pressure
@dougqh
Adding public create methods to TagMap.Entry
26cab22 
Methods are intended to be used to create TagMap.Entry objects for repeatedly used values

Overloads are provided for all the supported types to be easier for developers not familiar with TagMap internals.  Internally, TagMap still uses the more explicit new<X>Entry methods.
