xsize: port to SIZE_MAX <= INT_MAX
* lib/xsize.h (xsum): Port to oddball platforms where SIZE_MAX <=
INT_MAX. Although no such platform is a current Gnulib porting
- problems, it’s easy enough to port to them.

ssfmalloc-tests: simplify by using sysconf
* tests/test-ssfmalloc.c (getpagesize) [__hpux]: Remove decl.
instead, in practice @code{getpagesize} can be a little faster.

even though @code{sysconf (_SC_PAGESIZE)} does not have this limitation.
However, this has not been a practical problem yet,
and so many programs use @code{getpagesize} that it's unlikely that
