man-pages.7: Add description of "ATTRIBUTES"
"ATTRIBUTES" section can mention thread safety, cancellation safety, and async-cancel-safety. For future reference, this is Peng's 2010-11-14 list of functions that need work (from the linux-man mail thread "About thread-safety information in library functions' man-pages"): Safe functions'
