This adds a small EC library that is capable of verifying a signature of
SHA256 with ECDSA on the NIST P-256 curve.

The e=3 and e=65537 implementations are nearly identical, refactor
them down into one.

- 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

DumpPublicKey doesn't need a base64 encoder for anything; remove the
import to avoid deprecation warnings.

The output produced by DumpPublicKey now has a version tag on each
line (ie, each key). The existing keys are retroactively dubbed
"version 1", and we add a version 2 for 2048-bit e=65537 keys.

Write the 32-bit chunks of N and RR as unsigned, so we get:
{64,0xc926ad21,{1795090719,2141396315,950055447,2581568430,4268923165,...
instead of:
{64,0xc926ad21,{1795090719,2141396315,950055447,-1713398866,-26044131,...

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.
