Note in the manpage that the 2024 edition finally added ppoll(), and
also add the appropriate declarations for the correct versions of

include: ssp: round out fortification of current set of headers
ssp/ssp.h needed some improvements:
- `len` isn't always a size_t, it may need casted
- In some cases we may want to use a len that isn't specified as a
parameter (e.g., L_ctermid), so __ssp_redirect() should be more
flexible.
- In other cases we may want additional checking, so pull all of the
declaration bits out of __ssp_redirect_raw() so that some functions
can implement the body themselves.
strlcat/strlcpy should be the last of the fortified functions that get
their own __*_chk symbols, and these cases are only done to be
consistent with the rest of the str*() set.

include: de-macro __ssp_overlap(), improve semantics and checking
Switch away from pointer arithmetic to provide more obvious semantics
for checking overlap on pointer ranges. This lets us remove some casts
that need not exist and removes some possible fragility in its use.
While we're here, check for overflow just in case; sometimes we use a
caller-supplied size if __builtin_object_size(3) can't deduce the buffer
size, and we should fail the check if the size is nonsensical for the
provided buffers.
