d907bbbffd Fix invalid VHDX generation for image larger than 4Gb
- Part of BAT payload location was lost due to invalid
    BAT entry encoding type (32 bits instead of 64 bits)
- The sequence of PB/SB entries in BAT was broken due to
    off-by-one index check. It worked for smaller than
    4Gb because there were no SB entries in BAT.

aefd5f515c Add VHDX support to mkimg(1)
VHDX is the successor of Microsoft's VHD file format. It increases
maximum capacity of the virtual drive to 64TB and introduces features
to better handle power/system failures.

VHDX is the required format for 2nd generation Hyper-V VMs.
