as is with the slight adjustment to coexist with new implementation.

Use the guest's own p2m table instead of xc_get_pfn_list(), which
cannot handle PFNs with no MFN.
Dump a zeroed page for PFNs with no MFN.
Clearly deprecate xc_get_pfn_list().
Do not include a P2M table with HVM domains.
Refuse to dump HVM until we can map its pages with PFNs.

Get rid of USER|RW|ACCESSED L3 PTE flags which may be present
in a PAE guest when running on a 64bit hypervisor at save time.
This prevents the restore operation from getting confused by
these flags.
Reset disallowed L3E flags to match PAE case.

These have been used interchangeably, which is OK for PV domains but
not for HVM. This fixes an over-allocation by 256MB when restoring
HVM guests that have more than 4GB of RAM.

In the short term this allows us to save the same domain more than once.
Longer-term some more careful shared-info management will be needed.

Make some arch-specific #defines for page table handling
available unconditionally, add a suffix to avoid name clashes.
The versions without suffix are defined depending on the
architecture like they used to, so code using them continues
to work.

This patch makes libelf available to the tools, by symlinking the source

This patch adds a library with a small collection of helper functions
to parse and load elf binaries. The library handles endianess and
elfsize at runtime.
The patch also shuffles around the include files a bit. Now there is
*one* include file holding all the elf structures
(xen/include/public/elfstructs.h) which is included by everyone who
needs them.
It's dead code with this patch only, putting the code into use happens
in followup patches.

This kills off a fair amount of unpleasant CONFIG_COMPAT shimming and
avoids needing to keep the compat paths in sync as these interfaces
continue to develop.
