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

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.

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.

Some more stack memory wipe before leaving functions.
...
Note that I preferred to change the multiple returns to multiple checks
of a boolean to concentrate the erase into the last part of the
functions.
