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

533c3beb63 Fixed uncompress_coords for NIST curve 
The bn_sqrti was broken.  It didn't handle primes where all bits are set
in the lowest limb.

c983afd72f 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.

1d7fb4e38f 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.

f93b003cbc 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.

60e36dac3b Fixed conditional_negate for larger numbers 
Without the bn_mod the numbers get larger (but still < 2*prime), so
conditional_negate should handle this.

2. Removed many calls to bn_mod to prevent side-channel leakage.
