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.

bip32: serialization returns nu. of written bytes

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.

Remove fingerprint from hdnode structure (if you need it, call
hdnode_fingerprint on the parent hdnode).
Only compute public_key, when hdnode_fill_public_key is called.

BIP-32 without gaps, prepare non-ecdsa curves
...
* Split ecdsa_curve into curve_info and ecdsa_curve to support bip32 on
curves that don't have a ecdsa_curve.
* Don't fail in key derivation but retry with a new hash.
* Adapted test case accordingly
