Re: [Crash-utility] [PATCH] crash: Support a dumpfile in the flattened format.

I renamed the multi-purpose read_dump_file() function to be read_flattened_format(), and only call it when the dumpfile is a flat vmcore. For clarification/maintainability, I prefer to keep the original lseek/read calls in diskdump.c and netdump.c as they were, mainly because it's not intuitive to have the traditional netdump, kdump, and diskdump dumpfiles require an access function that is located in the new makedumpfile.c.
