Also fixes loss of CR2, DR6 and DR7 contents across HVM save/restore.

Not working yet as we are a bit too keen to kill the qemu-dm process,
before we know that the save has been successful.

It is no longer being maintained and probably shouldn't have existed in the
first place, since it was almost identical to xc_linux_build.c.

Instead of kludging a max_gpfn estimate in shared_info, add a new
XENMEM command to discover the actual maximum gpfn value as known by
the shadow code.
This needs to be more robust when we support HVM ballooning in future
anyway. One interesting point is that max_gpfn may be close to 4GB
even for small-memory HVM guests since for example SVGA LFB is mapped
into the I/O hole. We may need to special case the I/O hole somehow,
or provide some finer-grained way to find out which parts of the GPFN
space are actually used (e.g., get Xen to fill in a bitmap with 1 bit
per 1024 pages, or similar).

Change common Xen code to start all VCPUs (except idle ones)

So far the order isn't specified and may be random in theory.
But sorted array is requested by crash utility for efficient search.
Fortunately it is the case except ia64 full virtualized domain.
Update document such that those array must be sorted and fix the ia64
full virtualized domain case.

Make the differences clearer between the number of frames, the max PFN
and the size of the pfn array, and handle te framebuffer more cleanly.

These should not be set until the guest kernel kernel configures an
entry point otherwise the null_trap_bounce() check gets confused.
This change was made to the old domain builder in 12455:3fa6635d04b9
but was lost in the transition to the new builder.
