kfraser@localhost.localdomain d5cbf3ec58 x86: Add VGCF_onlien flag to vcpu_guest_context. 
Change common Xen code to start all VCPUs (except idle ones)
offline. Change arch code to deal with this.

kfraser@localhost.localdomain 4d42d7146c dump-core: store .xen_p2m or .xen_pfn section in pfn ascending order. 
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.

Ian Campbell 75c73974d7 [BUILDER]: Initialize code segment selectors in virtual IDT to 0. 
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.

Use the guest's own p2m table instead of xc_get_pfn_list(), which
cannot handle PFNs with no MFN.
Dump a zeroed page for PFNs with no MFN.
