Profile mode (was Re: Add std::unordered_* C++11 allocator support)

I have made some fixes and improvements in profile mode and recently
posted to my github (user gedare, repo stlprof) for another to try
out. I will try to send the shippable patches upstream soon. The
profile mode is interesting and useful to me as part of work done for
my ph.d. thesis, and I think can benefit from a few more improvements.
I do not know that I can spare the effort to "maintain" it, but maybe
I can review patches to avoid breaking it...
