This allows doing some of the steps before e.g. daemonization and some fater. Coming from btc@0cc8b6bc44bea29e24fa4e13d8a9bbe4f1483680
Before daemonization, just probe the data directory lock and print an
early error message if possible.
After daemonization get the data directory lock again and hold on to it until exit
This creates a slight window for a race condition to happen, however this condition is harmless: it
will at most make us exit without printing a message to console.

When a wallet is created it is registered in the validation interface (in CWallet::CreateWalletFromFile) but it is not immediately added to the wallets list. If a shutdown is requested before AddWallet (case more evident when -rescan is set) then m_internals can be released (in Shutdown -> UnregisterBackgroundSignalScheduler) before the wallet and then ReleaseWallet would call UnregisterValidationInterface with m_internals already released.

Effectively moving every validation interface callback to a background thread without locking `cs_main` for its entire process (each handler can now request `cs_main` lock only when/if they need it). This has a direct performance improvement on the synchronization time (which i haven't measured yet because there is one/two more PRs over the wallet and GUI areas, probably large as well, on top of this one and #2201 that should boost the sync time a lot more). Containing the following changes: * Adaptations coming from bitcoin#10286. * Adaptations coming from bitcoin#11824 (this one is different for us, take the base idea when you review it). Essentially solves a severe memory leak introduced previously in 10286 and improves `cs_main` lock acquisitions as well. * net_processing: decouple and refactor tier two inv data request processing. * bitcoin#12206 ACKs for top commit: random-zebra: Great job! 🍻 ACK 3d11027 Fuzzbawls: ACK 3d11027 Tree-SHA512: 60a25604fb8a3ad0553ccb074aed99c1b3c6f8a765b40c1b43f25412373cbd2a9e4f0f413d45cf694bd62e48512c936099ffb7a0d23a1b97576cb33283ca05ac

Effectively removing every `cs_main` lock from the wallet and GUI processing threads. Completely decoupling the wallet state and the visual interface update procedures from the main message and validation handler thread. Meaning that the messages & validation handler thread will be largely more active, accepting and verifying way more data in less time, not being affected by several other threads accessing to the main critical section. And, at the same time, the wallet and GUI worker threads will be able to perform and process their tasks concurrently, without waiting for the `cs_main` mutex acquisition. Improving the overall software performance, the GUI responsiveness and decreasing the synchronization time. To make this possible, the wallet is maintaining in memory a view of the chain and updating it only via the validation interface signals. Using the view to perform all of the chain related calculations. ACKs for top commit: Fuzzbawls: All good now, ACK ca3edc5 random-zebra: ACK ca3edc5 and merging...

A set of commits decoupled from #1973, solving #1840.
The final goal is #1973 but the scope there got pretty big and is requiring more previous back ports (like 9725 among others that are an entire branch of back ports by themselves) so.. better to start merging this sooner rather than later to not continue having issues on macOS deployment (or well, more specifically issues with newer boost versions).
