4a8f96f95d Improvements for epee binary to hex functions:
- Performance improvements
  - Added `span` for zero-copy pointer+length arguments
  - Added `std::ostream` overload for direct writing to output buffers
  - Removal of unused `string_tools::buff_to_hex`

6b145763f7 Fix clang build failure, caused by mixing C and C++
Easily fixed by moving a C++ header out of 'extern "C" {...}'.

When building with CC=clang CXX=clang++ make,

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: 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: "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.

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...

serialization: declare do_serialize specializations before use
This lets my gcc picks those instead of the generic template
where appropriate (and then fail since std::vector<something>
does not have a serialize method.
