There are vulnerabilities in multisig protocol if the parties do not
trust each other, and while there is a patch for it, it has not been
throroughly reviewed yet, so it is felt safer to disable multisig by
default for now.
If all parties in a multisig setup trust each other, then it is safe
to enable multisig.
Implements view tags as proposed by @UkoeHB in MRL issue
https://github.com/monero-project/research-lab/issues/73
At tx construction, the sender adds a 1-byte view tag to each
output. The view tag is derived from the sender-receiver
shared secret. When scanning for outputs, the receiver can
check the view tag for a match, in order to reduce scanning
time. When the view tag does not match, the wallet avoids the
more expensive EC operations when deriving the output public
key using the shared secret.

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.

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.
