Reintroduce BOARD_VOLD_EMMC_SHARES_DEV_MAJOR

Code taken from CM7's vold
vold: add ro.vold.umsdirtyratio property

This allows control of what /proc/sys/vm/dirty_ratio is used when USB mounting.
Some platforms like the HTC Desire (bravo) get a _HUGE_ performance boost when
writing to the sdcard when USB mounting if this is set to 20 (which is the default)
on the HTC Desire.

This addresses this issue: http://code.google.com/p/cyanogenmod/issues/detail?id=2949

Basicly it makes it possible to undo or control the effect of this commit:

cryptfs: also unmount /data/data before encrypting

galaxysmtd mounts /data/data on top on /data when unencrypted for
performance reason, so when encrypting, we need to unmount that
first before we can unmount /data.

On other devices, umount on a non-mounted folder will silently
succeed.
