Further, clean up many things to avoid needless differences to native
code, while also adding a couple of adjustments that only will be
submitted for native code inclusion, that simplify code, or that
remove unused elements.

I also added a one-liner that causes xenbus_dev_(error|fatal) to output
to the kernel log buffer (and thus syslog) which was invaluable to me
while debugging (by default, error messages only appear in xenstore).

It has been superceded by run-time flag
XENFEAT_auto_translated_physmap.
This patch changes behaviour slightly:
1. set_pmd/set_pgd/set_pud always use mmu_ops, even when
XENFEAT_writable_page_tables is available. Unclear whether
we want to add a test to avoid this.
2. xen_l1_entry_update always uses mmu_op. Again, could gate
this on XENFEAT_writable_page_tables.
3. We always pin/unpin pagetables. Could gate this on a
new XENFEAT flag.
