This patch is to refactor twrpDigest using polymorphism
and inheritance to use the same call patterns for creating and
reading a digest. Now a library.
Use SHA2 from libcrypto. SHA2 is default if device has libcrypto.
Change string MD5 everywhere to use digest or Digest instead. Updated
string tags to digest. Translation will be required.
Switch out digest code into a driver class from partitionmanager.
SHA2 is better for digest creation due to decreased collision space
compared to MD5 and SHA1.

Chances are there are not many themes in widespread use that are
using jpeg images, but this will be easy to revert back or even
just temporarily modify if we need jpeg support in a pinch.

For devices with an unusual aspect ratio, stretching a bitmap to
the screen resolution is sub-optimal. So let's reuse our XML engine
that allows assembling the splash screen from individual parts.
The splash page is loaded from a separate XML file for quick loading.
