blockchain_db: add k-anonymity to txid fetching
Read more about k-anonymity [here](https://en.wikipedia.org/wiki/K-anonymity). We implement this feature in the monero daemon for transactions
by providing a "Txid Template", which is simply a txid with all but `num_matching_bits` bits zeroed out, and the number `num_matching_bits`. We add an operation to `BlockchainLMDB` called
`get_txids_loose` which takes a txid template and returns all txids in the database (chain and mempool) that satisfy that template. Thus, a client can
ask about a specific transaction from a daemon without revealing the exact transaction they are inquiring about. The client can control the statistical
chance that other TXIDs (besides the one in question) match the txid template sent to the daemon up to a power of 2. For example, if a client sets their `num_matching_bits`
to 5, then statistically any txid has a 1/(2^5) chance to match. With `num_matching_bits`=10, there is a 1/(2^10) chance, so on and so forth.

replace most boost serialization with existing monero serialization
This reduces the attack surface for data that can come from
malicious sources (exported output and key images, multisig
transactions...) since the monero serialization is already
exposed to the outside, and the boost lib we were using had
a few known crashers.

For interoperability, a new load-deprecated-formats wallet
setting is added (off by default). This allows loading boost
format data if there is no alternative. It will likely go
at some point, along with the ability to load those.

Notably, the peer lists file still uses the boost serialization
code, as the data it stores is define in epee, while the new
serialization code is in monero, and migrating it was fairly
hairy. Since this file is local and not obtained from anyone
else, the marginal risk is minimal, but it could be migrated
later if needed.

Some tests and tools also do, this will stay as is for now.

Move OpenAlias console input back from libs
Library code should definitely not ask for console input unless
it's clearly an input function. Delegating the user interaction
part to the caller means it can now be used by a GUI, or have a
decision algorithm better adapted to a particular caller.

Add intervening v5 fork for increased min block size
Minimum mixin 4 and enforced ringct is moved from v5 to v6.
v5 is now used for an increased minimum block size (from 60000
to 300000) to cater for larger typical/minimum transaction size.

The fee algorithm is also changed to decrease the base per kB
fee, and add a cheap tier for those transactions which we do
not care if they get delayed (or even included in a block).
