RFR (XS) 8060245: update bsd version of jhelper.d to be in sync with the fix of 8009204 on solaris

[serguei.spitsyn at oracle.com]

Hi Coleen,

Thank you for looking at it!

Do you mean to move the jhelper.d + deps from bsd to posix?

I don't know how to answer your question.
What I understand is the jhelper.d has never been tested on bsd platform.
It can be a reason why there is almost no difference with solaris yet.

In order to use the jhelper.d the dtrace framework on bsd (or posix) 
must support helpers
in a similar way as it is done on solaris and implement jstack action.
I'd do as minimal as possible here until any commitment is seen in this 
area.
It is not clear why the jhelper.d was ported on bsd in the first place.

Please, let me know what is your opinion.

Thanks,
Serguei

In general, I have a question
