XEN3_DOM0: Move closer to GENERIC (NFC)
This is another step in making XEN3_DOM0 closer to GENERIC. It is
just reordering lines, adding commented out lines, and adding a few
comments. (Test-booted with no dmesg change.)
This pass is showing cases where there are substantive and likely
undesired changes (e.g., UFS_ACL is not defined in XEN3_DOM0). Often
I added them but commented them out to preserve the NFC property of
this commit. My plan is to finish the easy NFC stuff first before
addressing functional changes.
