Yu Ning 942d4e830b Support emulator's virtio-blk based SD card 
Currently, vold only supports MMC (for SD cards) and SCSI (for USB
drives) devices. It does not recognize any device whose major number is
not one of those used by MMC and SCSI. Unfortunately, virtio-blk is one
such device. It is used by the new Android emulator (a.k.a. qemu2,
featuring the "ranchu" virtual board) for SD card emulation.

In order to make this virtio-blk based SD card device appear in Android
and appear as an SD card (rather than a USB drive), changes have to be
made to both vold (wherever the device major number is checked) and
ranchu's storage configuration. This CL implements former.

This is a stop-gap solution for emulator in nyc.
A longer term solution in-tune with upstream kernel is in the pipes.

Updated from aosp/master version.
