xc_map_foreign_batch() can succeed partially. It is awkward to use
when you're only interested in complete success. Provide new
xc_map_foreign_pages() convenience function for that kind of use.
Also convert two obvious calls to use it.

On ia64 trying to map a foreign domain page which isn't allocated
cause annoying warning message. xm dump-core results in too many
warnings. With this hook, ia64 dump-core can suprress warning.

Presently nvram is stored in /usr/lib/xen/boot/nvram_<domain> next to the guest
firmware. This violates the FHS because /usr might be mounted read-only. This
patch moves the nvram storage to /var/lib/xen/nvram/nvram_<domain>
Also clean up:
- references to stat_buf assumed that stat() had succeeded; use access()
instead since it's easier and doesn't require stat_buf at all
- nvram_path[PATH_MAX] instead of nvram_path[100]
- strncpy(..., strlen(src)) is meaningless, re-order length tests to work
correctly

copy_from_GFW_to_nvram() in libxc forgot munmap() if NVRAM data
invalid. Also it forgot free() and close() too.

The new hypervisor will set shared_info->wc_* so do not clobber those
values with the saved versions from the old hypervisor.

This patch fixes the xc_map_grant_refs() function, which would fail
because, instead of passing the malloc()-ed ioctl argument pointer to
the ioctl, the address of this pointer was being passed instead.

Nvram saving is always executed even if a domain is destroyed by a
configuration parameter error. In this case, Nvram saving function
will get a bad address for the NVRAM data and save garbage into the
NVRAM file. Configuring a wrong vif parameter can expose this issue.
This patch fixes the issue by adding an address check function in
NVRAM saving path.
