hasher: Replace hasher_Double with HASHER_*D
...
This allows us to finely control when to use a single hash or a double hash in
various places. For example, Bitcoin signatures use double SHA256, but Decred
signatures use a single BLAKE256. However, both use double hashes for Base58.

Use bn_add instead of bn_addmod ( #80 )
...
The bip32 private key derivation used bn_addmod to handle
wrap around. This was never sufficient as bn_addmod uses only
bn_fast_mod, so an additional bn_mod is necessary. The bn_fast_mod
helped when bn_mod was not side-channel safe. Now that bn_mod uses
constant time code, we can get rid of the unnecessary bn_fast_mod
step and use bn_add instead of bn_addmod.

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.
