For the extensibility part, may I suggest that you turn
coredump_header.xch_nr_vcpus length into 16 bits and use the other 16
bits that left as an offset for a new header (PE style). I don't know
how old software will handle xch_nr_vcpus > 64K, as it always dumps
just the context for the first CPU.

But I understood that you are going to work on an ELF dump format...
good luck with that, it is surely needed!
