rct: do not serialize public keys in outPk
They can be reconstructed from vout

ringct: "simple" ringct variant
Allows the fake outs to be in different positions for each ring.
For rct inputs only.

ringct: do not serialize what can be reconstructed
The mixRing (output keys and commitments) and II fields (key images)
can be reconstructed from vin data.
This saves some modest amount of space in the tx.

add rct to the protocol
It is not yet constrained to a fork, so don't use on the real network
or you'll be orphaned or rejected.

ringct: add functions to commit to an amount
One to commit to an amount with zero key (for use with fake
commitments for pre-rct outputs), and one with an arbitrary
key (for rct outputs).

make rct tx serialization work
It may be suboptimal, but it's a pain to have to rebuild everything
when some of this changes.
Also, no clue why there seems to be two different code paths for
serializing a tx...

ringct: new {gen,decode}Rct APIs for convenience
A new version of genRct takes the mixRing as parameter, instead
of the inPk. inPk are part of the mixRing, and it is cleaner to
pass the mixRing data than to fetch it from the RingCT code.

A new version of decodeRct also returns the mask.

Also, failure to decode throws, so errors are properly detected.

serialization: declare do_serialize specializations before use
This lets my gcc picks those instead of the generic template
