ringct: always shutdown the boost io service
Even if no worker threads were started, it needs shutting down
or it will cause an invalid access in the io service thread

e1c7af35d4 cmake: transitive deps and remove deprecated LINK_*
Keep the immediate direct deps at the library that depends on them,
declare deps as PUBLIC so that targets that link against that library
get the library's deps as transitive deps.

Break dep cycle between blockchain_db <-> crytonote_core.
No code refactoring, just hide cycle from cmake so that
it doesn't complain (cycles are allowed only between
static libs, not shared libs).

This is in preparation for supproting BUILD_SHARED_LIBS cmake
built-in option for building internal libs as shared.

New "Halfway RingCT" outputs for coinbase transactions
When RingCT is enabled, outputs from coinbase transactions
are created as a single output, and stored as RingCT output,
with a fake mask. Their amount is not hidden on the blockchain
itself, but they are then able to be used as fake inputs in
a RingCT ring. Since the output amounts are hidden, their
"dustiness" is not an obstacle anymore to mixing, and this
makes the coinbase transactions a lot smaller, as well as
helping the TXO set to grow more slowly.

Also add a new "Null" type of rct signature, which decreases
the size required when no signatures are to be stored, as
in a coinbase tx.

rct amount key modified as per luigi1111's recommendations
This allows the key to be not the same for two outputs sent to
the same address (eg, if you pay yourself, and also get change
back). Also remove the key amounts lists and return parameters
since we don't actually generate random ones, so we don't need
to save them as we can recalculate them when needed if we have
the correct keys.

rct: rework the verification preparation process
The whole rct data apart from the MLSAGs is now included in
the signed message, to avoid malleability issues.

Instead of passing the data that's not serialized as extra
parameters to the verification API, the transaction is modified
to fill all that information. This means the transaction can
not be const anymore, but it cleaner in other ways.

rct: avoid the need for the last II element
This element is used in the generation of the MLSAG, but isn't
needed in verification.
Also misc changes in the cryptonote code to match, by mooo.

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.

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).
