[HVM] Save/restore: save shared-info pfn and re-map it on restore
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.

[XEN] Fix build breakage with gcc 4.1.2.

domain_build.c: In function 'construct_dom' :
domain_build.c:874: warning: pointer targets in passing argument 1 of 'strlcpy' differ in signedness

Unfortunately adding a simple cast to (char *) doesn't work since that
confuses safe_strcpy so revert to using strlcpy directly.

[HVM] Save/restore: clean up marshalling code
- All entries are now defined as structs and saved/restored
  in self-contained operations.
- Save/restore operations are type-safe, to tie each entry's
  typecode to a particular struct and its length.
- Save/restore handlers are registered once per host instead of
  per domain.
- Detect buffer overrun before it happens and abort.

[TOOLS] Fix foreign header build breakage.

Having both the Xen tree and the tools tree recurse into the foreign
headers directory causes headaches in parallel builds and when
building 32-bit tools + 64 bit Xen in the same tree.

Therefore we cause mk-symlinks to symlink in the foreign headers build
bits and generate a local version of the headers and checker tool.

Only libxc needs to do this since the other tools were actually
picking up the libxc version of the headers anyway so the mk-symlinks
calls can be removed from these components.
