TokenBuffer support for setting streamWriteConstraints

[pjfanning]

The TokenBuffer will inherit the default StreamWriteConstraints. We'll need a way to allow users who want to support deeply nested data to have TokenBuffer run with a custom StreamWriteConstraints.

Relates to FasterXML/jackson-core#1055

Possibly. If I remember correctly, there are methods in SerializerProvider to be used for constructing instances, instead of direct construction -- if so, there'd be access to underlying JsonFactory which should give access I think.
Ability to override this setting would be useful as well. Same holds true for StreamReadConstraints if not already handled.

[pjfanning]

The StreamReadConstaints come from the JsonParser instances that are passed to the TokenBuffer. The StreamWriteConstaints could come from the JsonGenerator instances.

[cowtowncoder]

@pjfanning Yes, definitely in cases where JsonGenerator is passed (or can be passed)

[cowtowncoder]

@pjfanning Is this still needed?

[pjfanning]

Maybe best to wait for a real world issue instead of trying to be proactive on this.

Ok, will close; easy enough to re-open if/when requested.
