limits.h: define PAGE_SIZE only if XSI is requested

Browse Source 
limits.h is part of the C standard, but POSIX and XSI extend it with
various defines. We should not add these unless the application requests
support for them.

In this case, PAGE_SIZE should only be defined if XSI support is
requested by defining _XOPEN_SOURCE. Note that PAGESIZE (plain POSIX for
the same thing) and B_PAGE_SIZE are alternatives that remain available.
