Adds a length check to `send` that checks whether the metric being sent is longer than the max buffer size. An exception is raised to the caller (*not* in the reaper thread) if the metric is too large. In order to check the length before adding the item to the reaper thread, the UTF8 building had to move to be done in the calling thread rather than the background. Prior to this, if a chunk larger than the max buffer size made it into `builderAction` it would cause an infinite loop. It would try to flush existing chunks to make room for the new one, but would then get stuck because the oversize chunk was still too big. The exact same thing would happen on the next `builderAction` iteration (and so forth). Fixes iand675#32.

@iand675 I just noticed this. Any thoughts? I'm not using datadog much these days so I'm not sure of the context. |
