Protect signing against side-channel attack ( #81 )
...
Signing uses the bn_inverse function that is prone to side-channel
attacks. We randomize its argument by multiplying it with a random
non-zero number. At the end we multiply again by the same number to
cancel it out.
Changed get_k_random to take the prime range as a second argument and
to return a non-zero number. This function was previously only used
for (non-rfc6979) signing and is now used for side-channel protection.

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.
