Things like UBI volume table, UBI fast-map stuff are not "headers", so I
am not sure if using word "headers" a good idea. Probably we want
options like --ubifs and --ubi to denote ubi and ubifs-level stuff. The
default would be "everything".

But again, if you start smaller, and upstream a good tool for
UBIFS-level stuff, it will be easier to add UBI stuff separately.

Besides, I have some additional vision, which you do not have to
implement, but which should be taken into account. E.g., ubidump which
does not need UBI/UBIFS drivers, ubidump which can deal with an image
generated with nanddump without "mounting" it, etc. So I was thinking
doing small steps at a time would make it easier for me and for you to
make a tool which has limited functionality today, but which can be
later extended to support more functionality.
