Doug Zongker 8fdbf97652 mincrypt: merge the two RSA verifiers
The e=3 and e=65537 implementations are nearly identical, refactor
them down into one.

Doug Zongker 515e1639ef mincrypt: support SHA-256 hash algorithm
- 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

Doug Zongker ede5cf6533 remove unneeded import
DumpPublicKey doesn't need a base64 encoder for anything; remove the
import to avoid deprecation warnings.

Doug Zongker 35d9ad5ae7 support e=65537 for libmincrypt, DumpPublicKey
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.

Doug Zongker 5e12d739c6 make DumpPublicKeys write 32-bit values as unsigned
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,...

Doug Zongker 90b06ac786 only use faster SHA-1 code on machines with good libc
Macs don't have byteswap.h or endian.h.  Change conditionals to only
use the faster SHA-1 code on little-endian machines with byteswap.h.

Doug Zongker a6de77de17 add optimized SHA1 algorithm
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.
