Request for review (S, UPDATED) 7017193: Small memory leak in get_stack_bounds // os::create_stack_guard_pages

[Dmitry Samersoff]

[got mailer error for openjdk alias, so resending]

Hi Everyone,

Here is updated fix:

http://cr.openjdk.java.net/~dsamersoff/7017193/webrev.03/

I introduce a new convenience function primary designed to read variety 
of /proc files. It reads first N characters of line and then skip until eol.

Than get_stack_bounds() is changed to use it instead of stdio getline();

-Dmitry
