Reworked rfc6979 signing. ( #72 )
...
This adds an is_canonic parameter to all sign functions. This is a
callback that determines if a signature corresponds to some coin
specific rules. It is used, e. g., by ethereum (where the recovery
byte must be 0 or 1, and not 2 or 3) and or steem signatures (which
require both r and s to be between 2^248 and 2^255).
This also separates the initialization and the step function of the
random number generator, making it easy to restart the signature
process with the next random number.

- Fix the bug where we zero too many bytes in sha512_Last
(SHORT_BLOCK_LENGTH != BLOCK_LENGTH -2).
- Get rid of an if branch.
- Don't reverse the last two words in 512_Last that are written later.
- make 256_Final and 512_Last look the same.

Moved get_ethereum_address from ecdsa to bip32
...
The new name of the function is `hdnode_get_ethereum_address`
and it gets a hdnode as input as opposed to a public key. This
also avoids first computing the compressed public key and then
uncompressing it.
Test cases were adapted to work with new function. The test-vectors
are the same as for bip32 and independently checked with an adhoc
python implementation.

Faster PBKDF2 by reusing intermediate results.
...
The old implementation needed 6 sha transformations per iterations:
- 2 for computing sha512 of seed,
- 2 for computing digests of ipads/opads,
- 2 for computing digests of intermediate hashes.
The first 4 transformations are the same in every iteration so we cache
them. A new function hmac_sha512_prepare computes these digests.
We made sha512_Transform visible in pbkdf2 and prevent unneccessary
big/little endian conversions back and forth.
