Accepting request 212604 from home:arvidjaar:grub2-next

I think it is good time to update to 2.02 so it can get more testing.
Although internal changes are pretty extensive, externally it should be
pretty much the same. The main user visible changes are

 - autogen is not used anymore, so we can finally simplify patches
   and recreate files during RPM build. So generated files need not be
   patched and shipped any more.

 - GRUB_HIDDEN_TIMEOUT is deprecated, we should use GRUB_TIMEOUT_STYLE
   instead. This will need perl-Bootloader and YaST changes. Old config
   is still accpepted so nothing should be broken.

 - native pvgrub2 support for Xen PV guests.

 - ARM support (32 and 64 bit), although it has rough edges.
