Fixed unit test for addmod added test for add.
...
- bn_addmod: now only guarantees result < 2*prime.
- bn_add: new test
- bn_mult_half: fixed normalization of prime -> 0.

Extended comments, new function bn_add, a bug fix.
...
Describe normalized, partly reduced and reduced numbers.
Comment which function expects which kind of input.
Removed unused bn_bitlen.
Add bn_add that does not reduce.
Bug fix in ecdsa_validate_pubkey: bn_mod before bn_is_equal.
Bug fix in hdnode_private_ckd: bn_mod after bn_addmod.

Fixed conditional_negate for larger numbers
...
Without the bn_mod the numbers get larger (but still < 2*prime), so
conditional_negate should handle this.

Cleaned up bignum code
...
1. Fixed bn_multiply_step to handle small primes.
2. Removed many calls to bn_mod to prevent side-channel leakage.

two bugfixes: 1. nist256p1.c was not included in setup.py, causing import errors when using TrezorCrypto.so in Python. 2. if you attempted a hardened derivation in python using the compiled TrezorCrypto module, an IntegerOverflowError would occur because Python ints are always signed. one-line fix by changing int to unsigned int in the pyx file
