Don't share privregs with hvm domain and twist IA64 xen dump core format
slightly. Xen shares privregs pages with IA64 HVM domain for xm dump-core
to dump the pages. However sharing the page allows hvm guest domain
peek/destroy the page contents that might cause xen crash. And the xen
dump core file doesn't need privregs page because cpu context should be
obtained from vcpu context in case of IA64 HVM domain.
Although this patch modify xen dump core format, current crash utility
(at least crash 4.0-4.7) doesn't look into .xen_ia64_mmapped_regs section
and I don't know any other tools to understand xen dump core file.
So this format modification doesn't cause incompatibility issue.

I have added CONFIG_PASSTHROUGH in ioemu/Makefile.target and
ioemu/hw/pc.c in attached vtd_tools2.patch. This should turn off
libpci usage by default until user specifically enables it.
This can be safely check-in without breaking builds for people who do
not care about pass-through devices. I will try to think of a better
way to enable this.

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.

Prevent warning message when xm dump-core
Using foreign p2m exposure, we can avoid to map the page which isn't allocated.

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
