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: parseSigCompact use Buffer API
parseSigCompact also now returns the correct recovert parameter without
the need to subtract the compression bit.
This makes it easier to use.

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.

Fix signing with compressed keys
calcPubkeyRecoveryParam always assumed a non-compressed key, and was comparing
the address generated from a non-compressed public key against the original
address generated from the compressed public key.
This commit fixes it by passing the entire pubkey object, and configuring the
generated address to use the same compressed setting as the original one.
