Code modifications to integrate Ledger HW device into monero-wallet-cli. The basic approach it to delegate all sensitive data (master key, secret ephemeral key, key derivation, ....) and related operations to the device. As device has low memory, it does not keep itself the values (except for view/spend keys) but once computed there are encrypted (with AES are equivalent) and return back to monero-wallet-cli. When they need to be manipulated by the device, they are decrypted on receive. Moreover, using the client for storing the value in encrypted form limits the modification in the client code. Those values are transfered from one C-structure to another one as previously. The code modification has been done with the wishes to be open to any other hardware wallet. To achieve that a C++ class hw::Device has been introduced. Two initial implementations are provided: the "default", which remaps all calls to initial Monero code, and the "Ledger", which delegates all calls to Ledger device.

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.
