What Does This Do

Adds methods to TagMap.Entry to create entries directly
Adds methods to AgentSpan / DDSpan to set TagMap.Entry(Reader) directly

Motivation

The intention is to enable reuse of TagMap.Entry objects to further reduce allocation
Those improvements have been prototyped and shown to be beneficial, but will be done in separate pull requests

I'd originally hoped to make reuse of TagMap.Entry-s hidden from instrumentation by adding in caches behind the scenes, but that approach didn't pan out. The caches were beneficial when memory was scarce, but harmful when memory is plentiful.

So for now, the simplest approach is to expose APIs, so TagMap.Entry-s can be used directly in the key places where doing so is beneficial. Examples include static meta information, git related tags, db connection info, etc

Additional Notes

It will probably also make sense to extend these changes to TraceSegment; however, TagMap isn't currently visible to TraceSegment at build time. To keep this pull request simple, changing TraceSegment is left to another pull request

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.

Direct TagMap.Entry support in AgentSpan / DDSpan

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.
