swapon.2: <sys/vmparam.h> and <vm/swap_pager.h> weren't being displayed,
because .It is for a list item whereas .In is for included files.
Also, we want a blank line between <sys/ > headers and the other

Document EINTEGRITY errors for many system calls.

EINTEGRITY was previously documented as a UFS-specific error for
mount(2). This documents EINTEGRITY as a filesystem-independent error
that may be reported by the backing store of a filesystem.

mount(2) and posix_fadvise(2). EIO was previously only documented for
UFS for mount(2).
