(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.

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.
