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.

Fixes a bug in the test_pbkdf2_hmac_sha256 test.
...
This bug fix sets the length of the derived key in the last test_pbkdf2_hmac_sha256 test to 40 bytes to fix a buffer overflow, which is caused by the call to the pbkdf2_hmac_sha256 function, on the memory reserved by the local variable k.

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.

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