Title: Deprecated instrumentation API

The instrumentation logic needed by the Scala IDE Worksheet is currently part
of the Scala project, but it doesn't need to be. I already have a PR ready for
completely removing the instrumentation logic, but I considered it too risky at
this point for 2.10.0 release (an oversight can lead to the impossibility of
running the worksheet with Scala 2.10.0).

For the moment, I believe it's better to deprecate the whole instrumentation
API in 2.10.0, and the PR for removing the instrumentation logic will target
2.10.1 or 2.11.0.

Besides deprecating the instrumentation API, this commit also raised visibility
of `interruptsEnabled` member in `Global`. This change alone is sufficient for
moving the instrumentation logic outside of the compiler, and it is needed
because the Presentation Compiler thread should never be interrupted while
instrumenting a source.
