Adding instrumentation points for tracing of I/O calls

[Seán Coffey]

The main review and code approval for this belongs on the 
core-libs-dev at openjdk.java.net and that looks to be progressing well.

Approved for 7u-dev push once you have code review approval. Please 
consider porting any related enhancements (to jdk8 code) into the 7u-dev 
repo also (once available). On that note, would it be easier to push 
identical changesets to 7u & 8 for now ? I'll leave that for you to decide.

Regards,
Sean.

The consensus in that thread is that the changes look good, but should ideally be replaced by dynamic bytecode instrumentation. Because of the short time remaining for 7u12, I will not have time to redo the implementation for this release. Thus the suggested plan was to make the proposed change in 7u12 and do dynamic bytecode instrumentation for 8.
