ecdsa: adhere strictly to RFC6979
...
The previous impl. was in breach of the following section:
> Please note that when k is generated from T, the result of bits2int is
> compared to q, not reduced modulo q. If the value is not between 1 and
> q-1, the process loops.
> Performing a simple modular reduction would induce biases that would be
> detrimental to signature security.

ec/dsa: extract P_OVER_FOUR as a curve specific constant
...
This actually resolves a possible bug if multiple ecparams were used
(aka different values for P_OVER_FOUR, but only the cached was used).

ecdsa: add serializeSigCompact and tests
...
This also adds tests for all other ECDSA serialize/parsing functions.
The k, r, s and D values were sourced from test vectors on
https://bitcointalk.org/index.php?topic=285142.40 .
The compact signatures (aka, i values) were generated from bitcoinjslib, but they
are straight forward anyway.
