Add lollipop decrypt support

Kang in cryptfs.c and cryptfs.h from vold.
Use TW_INCLUDE_L_CRYPTO := true to enable.
Ramdisk must contain the normal fstab file in the root in the
usual format of:
fstab.{ro.hardware}
For examble for Nexus 5:
fstab.hammerhead
Or on many Qualcomm devices:
fstab.qcom

Tested against Android 5.0 lollipop on Nexus 7 2012 grouper. Not
sure if or how this will work when we are dealing with a device
with a hardware keystore. Long term we need to add a GUI element
to allow entering a pattern. For now you can decrypt a pattern
unlock by converting the dots to numbers in the following format:
123
456
789

So an upper-case L would translate to 14789 as a password entered
on the keyboard.
