Integrate the changes that occurred in POSIX.1-2008 into the
main list (to be consistent with the list, elsewhere on this
page, of functions that are cancellation points).
Also, fix an error that said that strerror() was added to
the list in POSIX.1-2008. It was strsignal() that was
added. (strerror() was already in the list in POSIX.1-2001.)

Switch these pages to do similar.

The page was a bit fuzzy in describing the return values for
various cases. In particular, it needed to be more explicit
in describing what happens for the "not found" case.
This is an analogous change to the previous change for
getpwnam.3, made after Andreas Henriksson's report.

a thread ID argument, that ID by definition refers to a thread
in the same process as the caller.
