gen_stream test suite fix for spurious process count failure

I changed the test suite for gen_stream to not rely on
erlang:system_info(process_count).  Instead I exposed the processes using
a new interface and check the actual number processes returned by the
gen_stream server.

git fetch git:// gen_stream-test-track-procs

I hope this works.  I pulled a recent dev, then got jn/gen_stream and
applied it as a patch on top of my dev.  My new changes plus the patch are
all bundled into this single commit.

I only changed two files:

If you have any trouble, just cherry pick these two files and apply them
on top of jn/gen_stream in pu.

This fixes the spurious random failures.  It does not attempt to address
the failure caused in the shell test suite.  I think I know how to track
that one down and hope to get to it in the next few days.
