ringct: guard against bad data exceptions in worker threads 
If purported pubkeys aren't actually valid pubkeys, exceptions
will fly. These will terminate if thrown in a worker thread.
Guard against this.

redfish 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.

make rct tx serialization work

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.
