It avoids dividing by 8 when deserializing a tx, which is a slow
operation, and multiplies by 8 when verifying and extracing the
amount, which is much faster as well as less frequent
RefreshOptimizeCoinbase was an optimization to speed up scanning of coinbase transactions before RingCT (tx version 2) where they split miner reward into multiple denominations, all to the same wallet.
When RingCT was introduced, all coinbase transactions became 1 output only, so this optimization does nothing now.
With p2pool, this optimization will skip scanning p2pool payouts because they use more than 1 output in coinbase transaction.
Fix it by applying this optimization only to pre-RingCT transactions (version < 2).
- matches the paper by Miller et al to apply the gamma from chain tip, rather than after unlock time
- if the gamma produces an output more recent than the unlock time, the algo packs that output into one of the first 50 spendable blocks, respecting the block density factor
On Mac, size_t is a distinct type from uint64_t, and some
types (in wallet cache as well as cold/hot wallet transfer
data) use pairs/containers with size_t as fields. Mac would
save those as full size, while other platforms would save
them as varints. Might apply to other platforms where the
types are distinct.
There's a nasty hack for backward compatibility, which can
go after a couple forks.
do not include blocked hosts in peer lists or public node lists by default,
warn about no https on clearnet and about untrusted peers likely being spies

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.
