Much of the bootloader interaction (including the Solaris and NetBSD
portability bits) are translated pretty much directly from the python
in tools/python/xen/xend/XendBootloader.py

Useful if you need to read a guest filesystem (e.g. pygrub).
I'm not overly thrilled with the implementation WRT tap interfaces,
particularly WRT to detach. I was unable to find a way to get at the
paramters necessary to call tap_ctl_destroy so I assumed for now it
that is OK to assume that the tap device is going to be wanted for the
actual domain at some point in the immediate future and hence there is
no pressing need to destroy it.

This will allow us to map and then unlink the file and therefore
delete the process on process exit or explicit unmap.
Using the mmaped versions of these files required rewriting build_pv
to use the xc_dom builder functionality directly rather than through
the xc_linux_build "compatibility layer". (The status of the
xc_linux_build interface as a compatibility layer seems a bit dubious
since all existing callers use it but if anything is going to replace
it then libxl seems like the likely candidate).
I'm not thrilled with the definition of the maps lifecycle. This could
be solved by adding a helper function to explicitly free the toplevel
structure.

Use this to run xenconsole as the foreground process and move the
connection to the console in the "create -c" case early enough to be
able to view output from the bootloader. This behaviour is consistent
with how both "xm console" and "xm create -c" operate.

There is an unfortunate warning for the empty format string by default
which I workaround by adding -Wno-format-zero-length.

This can just mean we have raced with the bootloader exiting and if we
continue we will likely see the real domain console show up.

libxl would rather like to parse the output of pygrub. Rather than
implement an SXP parser in libxl add a --output-format option to
pygrub which can select an alternative, simpler to parse,
format. Available formats are:
sxp: current SXP output format;
simple: simple key+value output with \n separating item ( for
debugging). key and value are separated by a single
space (and key therefore cannot contain a space);
simple0: as simple but with \0 as a separator;
Also add --output-directory to allow temporary files to be placed
somewhere other than /var/run/xend/boot.

According to Intel 64 and IA32 Architectures SDM 3B Appendix B, Intel
Nehalem/Westmere processors provide h/w MSR to report the core/package
cstate residencies.Extend sysctl_get_pmstat interface to pass the
core/package cstate residencies, and modify xenpm to output those
information.

Implement parsing for timer_mode, hpet and vpt_align parameters.
These are all HVM only parameters and hpet/vpt_align are boolean so
change types and place in hvm union accordingly. Also HPET is x86 only
on principle so make this compile-time conditional on arch as-is
viridian.

The OCaml xenstored supports the XS_RESTRICT operation, which
deprivileges a dom0 xenstore connection so it can only affect one
domain's entries. Add the relevant definitions to the C libraries
so that callers can use it.

I don't think protocol specific data really belongs in this header
but since it is already there and we seem to be stuck with it let's at
least make the users explicit lest people get caught out by future new
fields moving the pad field around.
This is the Xen portion of this change. The kernel portion will be
sent separately. There is no dependency between the two.

This is the patch to fix pyGrub default value when it's being set out of
range. This patch makes the quiet and interactive mode select the same
default image when the default value for boot entry is out of range,
i.e. when the guest is having wrong configuration in it's boot loader
(like 3 entries with default mistakenly set to 10 etc).
When the boot entry number is being set out of range it falls back to 0
(first entry of boot loader).
