- adds a library to compute the SHA-256 hash
- updates the RSA verifier to take an argument specifying either SHA-1
or SHA-256
- updates DumpPublicKey to with new "key" version numbers for
specifying SHA-256
- adds new argument to adb auth code to maintain existing behavior

This optimized implementation of the SHA1 algorithm is about 28%
faster than the old one (on sapphire hardware) but assumes
little-endianness. Add it, but continue using the old implementation
on big-endian hardware.
