[RFC] Allow separate boot block and core.img location?

There are many users using dual boot with Windows and Linux. In this
configuration installing grub in MBR unfortunately breaks at least some
updates of Windows 8 (update fails). And installing grub in partition
has all sort of known problems with blocklists.

What about allowing separate locations for boot block and core.img?
I.e. something like

grub-install --boot-block-location=/dev/sda1
--core-img-location=/dev/sda

This has all advantages of embedding core.img while allowing leaving
MBR alone. Actually we could assume default --core-img-location, meaning
that for

grub-install --boot-block-location=/dev/sda1

we assume that core.img has to be embedded in /dev/sda unless proved
otherwise :)
