Add various common utility functions. These will be used by a forthcoming re-written UMS test, and a brand-new DFU test.

+def md5sum_data(data):

• '''Calculate the MD5 hash of some data.
• Args:

•    data: The data to hash.
  

• Returns:

•    The hash of the data, as a binary string.
  

• '''
• h = hashlib.md5()
• h.update(data)
• return h.digest()

Or just:

return hashlib.md5().update(data).digest()

I was going to do that, but it doesn't look like update() returns the hash object, so I can't chain at least the .digest() call together, so I may as well leave it as-is.
