wallet: factor transfer_rct code with transfer code
The "transfer" simplewallet command is renamed to "transfer_original".
"transfer_new" is renamed "transfer", "transfer_rct" is removed,
and the new "transfer" now selects rct or non rct transactions
based on the current block height.

move the rct commitments to the output_amounts database
Since these are needed at the same time as the output pubkeys,
this is a whole lot faster, and takes less space. Only outputs
of 0 amount store the commitment. When reading other outputs,
a fake commitment is regenerated on the fly. This avoids having
to rewrite the database to add space for fake commitments for
existing outputs.

This code relies on two things:

- LMDB must support fixed size records per key, rather than
per database (ie, all records on key 0 are the same size, all
records for non 0 keys are same size, but records from key 0
and non 0 keys do have different sizes).

- the commitment must be directly after the rest of the data
in outkey and output_data_t.

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.

Use the supplied hard fork version in validate_miner_transaction
rather than using the current one. No functional changes, but may
save some bugs in the future.

wallet: reset output spent status on blockchain reorg
If the blockchain gets reorganized, all outputs spent in the part
of the blockchain that's blown away need to be reset to unspent
(they may end up spent again on the blocks that replace the blocks
that are removed, however).

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.

db_lmdb: update reset for recent db changes
- we need to drop the new m_tx_indices database
- we reset the version to current version

This fixes the core tests failing to initialize.

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.
