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.

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.

Compute pubkey only on demand.
...
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

Added curve type to HDNode
...
Every curve gets it's own hierarchy and the curve is remembered in
HD node. Fixed the private/public key derivations to use the right
modulus.
