ktrace: make ktr_tid a long not intptr_t (NFC)

Long ago, ktr_tid was ktr_buffer which pointed to the buffer following
the header and was used internally in the kernel. Use was removed in
efbbbf570d70b and it was repurposed as ktr_kid in c6854c347f4d8. For
ABI reasons, it stayed an intptr_t rather than becoming an lwpid_t at
the time. Since it doesn't hold a pointer any more (unless you have
a ktrace.out from 2005), change the type to long which is alwasy the
same size on all supported architectures. Add a suggestion to change
the type to lwpid_t (__int32_t) on a future ABI break.

Remove most remaining references to ktr_buffer, retaing a comment in
kdump.c explaining why negative values are treated as 0. While here,
accept that pid_t and lwpid_t are of type int and simplify casts in
printf.

This changed was motivated by CheriBSD where intptr_t is 16-bytes
in the pure-capability ABI.

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.

While here, document EIO as a filesystem-independent error for both
mount(2) and posix_fadvise(2). EIO was previously only documented for
UFS for mount(2).
