Anna Henningsen 2205f85b2c stream: improve performance for sync write finishes
Improve performance and reduce memory usage when a writable stream
is written to with the same callback (which is the most common case)
and when the write operation finishes synchronously (which is also
often the case).

Brian White 686984696d stream: improve Readable.read() performance
read() performance is improved most by switching from an array to

also contribute include: making some hot functions inlinable, faster
read() argument checking, and misc code rearrangement to avoid
unnecessary code execution.
