A reorg can end up causing an output's position in the chain to
move. Since the wallet doesn't update the RingDB on reorg, it
may refer to the output's stale position in the chain.
This seems a reasonable solution rather than introducing complex
logic to update the stale ring member's value on rerog, since
RingDB can be deprecated with FCMP++.
Fix four issues with wallet_keys_unlocker:
1. It won't decrypt if there are unlockers open simulataneously on multiple `wallet2` instances
2. It won't decrypt if the first unlocker was disabled (i.e. `locked=false`), even with a second non-disabled unlocker
3. If a destructor of an earlier unlocker is triggered before the destructor of a later unlocker, it will re-encrypt too early, while the second unlocker is still in scope
4. Calling the 3-parameter constructor with `locked=true` after an unlocker already exists will "double-encrypt" the spend key after its destructor since the local variable is `locked=false` and the field member is `locked=true`
Also, replace `wallet2::decrypt_account_for_multisig` with `wallet_keys_unlocker`.
Rings for outgoing transactions are stored within the scanning code since the last hardfork,
so this code is largely unneccessary now.

The commit kills support for deprecated ephemeral Boost messages: signed/unsigned transaction sets, pending transactions, reserve proofs, MMS messages, etc.
It does NOT kill support for loading very old wallets in Boost format, that should be supported indefinitely. These messages were deprecated 5 years ago. Since
then, we have had a hard fork to enable a new non-compatible transaction type (w/ view tags), and disable the old transaction type. This renders basically all
of the aforementioned messages before that HF useless, with the possible exception of reserve proofs.
This commit also cleans up dead inclusions of boost serialization headers.
This commit is part of upstreaming Carrot/FCMP++. Killing support for Boost messages now means less boilerplate Boost serialization review for Carrot/FCMP++.
a. `critical_section` is functionally identical to a `boost::recursive_mutex`
b. `critical_region_t` is functionally identical to a `boost::unique_lock`
c. remove some vestigial definitons `g_test_dbg_lock_sleep` as a variable
