xennet_fill_frags() uses ~0U as return value when the sk_buff is not able

This series is mostly Wei's effort to switch from xenheap to domheap for
Xen page tables. In addition, I have also merged several bug fixes from
my "Remove direct map from Xen" series [1]. As the title suggests, this
series switches from xenheap to domheap for Xen PTEs.

From: Wei Liu
The pl2e and pl1e variables are heavily (ab)used in that function. It
is fine at the moment because all page tables are always mapped so
there is no need to track the life time of each variable.
We will soon have the requirement to map and unmap page tables. We
need to track the li

From: Wei Liu
We are going to switch to using domheap page for page tables.
A new set of APIs is introduced to allocate, map, unmap and free pages
for page tables.
The allocation and deallocation work on mfn_t but not page_info,
because they are required to work even before frame table is set up
From: Wei Liu
After inspection ARM doesn't have alloc_xen_pagetable so this function
is x86 only, which means it is safe for us to change.

They were put into page.h but mm.h is more appropriate.
The real reason is that I will be adding some new functions which
takes mfn_t. It turns out it is a bit difficult to do in page.h.

This then requires moving declaration of root page table mfn into mm.h
and modify setup_cpu_root_pgt to have a single exit path.
We also need to force map_domain_page to use direct map when switching
per-domain mappings. This is contrary to our end goal of removing
direct map, but
