Implement checks for get/setxattr at the syscall layer.
Add checks for input arguments, file type, permissions, etc. that match
the Linux implementation. A call to get/setxattr that passes all the
checks will still currently return EOPNOTSUPP. Actual support will be
added in following commits.
Only allow user.* extended attributes for the time being.
