This PR is a subset of the work done in the context of #13100. This change consists in extracting from the application class the code that manages the wallet models.
The role of the `WalletController` instance is to coordinate wallet operations and the window.

It includes the following policy changes:
* All GetRand* functions seed the stack pointer and rdrand result
(in addition to the performance counter)
* The periodic entropy added by the idle scheduler now seeds stack pointer,
rdrand and perfmon data (once every 10 minutes) in addition to
just a sleep timing.
* The entropy added when calling GetStrongRandBytes no longer includes
the once-per-10-minutes perfmon data on windows (it is moved to the
idle scheduler instead, where latency matters less).
Other changes:
* OpenSSL is no longer seeded directly anywhere. Instead, any generated
randomness through our own RNG is fed back to OpenSSL (after an
additional hashing step to prevent leaking our RNG state).
* Seeding that was previously done directly in RandAddSeedSleep is now
moved to SeedSleep(), which is indirectly invoked through ProcRand
from RandAddSeedSleep.
* Seeding that was previously done directly in GetStrongRandBytes()
is now moved to SeedSlow(), which is indirectly invoked through
ProcRand from GetStrongRandBytes().
This guarantees that OpenSSL is initialized properly whenever randomness
is used, even when that randomness is invoked from global constructors.
Note that this patch uses Mutex directly, rather than CCriticalSection.
This is because the lock-detection code is not necessarily initialized
during global constructors.

fb3ce75807 Don't label transactions "Open" while catching up (Hennadii Stepanov)
Pull request description:
Fix#13299.
Since the default `nSequence` is `0xFFFFFFFE` and locktime is enabled, the checking `wtx.is_final` is meaningless until the syncing has completed (ref: #1026).
This PR makes the wallet mark a transaction "Unconfirmed" instead of misleading "Open for NNN more blocks" when syncing after a period of being offline.

Currently the `unloadwallet` RPC is asynchronous, it only signals the intent to unload the wallet and then returns the response to the client. The actual unload can happen later and the client has no way to be notified of that.
This PR makes the `unloadwallet` RPC synchronous, meaning that it blocks until the wallet is fully unloaded.

There was only one place in the codebase where we're directly reading >32 bytes from
the RNG. One possibility would be to make the built-in RNG support large reads, but
using FastRandomContext lets us reuse code better.
There is no change in behavior here, because the FastRandomContext constructor
uses GetRandBytes internally.
9d0e52834 implements different disk sizes for different networks on intro (marcoagner)
Pull request description:
Fixes https://github.com/bitcoin/bitcoin/issues/13213.
Mostly, I layed out the concept to open the PR for refinement and getting feedback if the approach is okay. Changes are expected.
Two points:
- The values for both new consts `TESTNET_BLOCK_CHAIN_SIZE` and `TESTNET_CHAIN_STATE_SIZE` is certainly not optimal; I just checked the size of my testnet3 related dirs and set them to little bit higher values. Which values should be used?
- Should we do something like this to regtest? Or these "niceties" do not matter when on regtest?
Thanks!

fa48baf23e wallet: Avoid leaking locktime fingerprint when anti-fee-sniping (MarcoFalke)
453803adc9 [test] wallet_txn_clone: Correctly clone txin sequence (MarcoFalke)
Pull request description:
The wallet sets the locktime to the current height of our active chain. This is fine, as long as our node is connected to other nodes. However, when we fall back and get stuck at a particular height (e.g. taking the wallet offline), the same (potentially unique) locktime is used for all transactions. This makes it easier for passive observers to cluster transactions by wallet.
For reference, I visualized "locktime-reuse" with the data:
* blocks 545k-555k (both inclusive)
* locktimes<=60k
* excluding coinbase txs

ca126d490b Fix out-of-bounds write in case of failing mmap(...) in PosixLockedPageAllocator::AllocateLocked (practicalswift)
Pull request description:
`mmap(...)` returns `MAP_FAILED` (`(void *) -1`) in case of allocation failure.
`PosixLockedPageAllocator::AllocateLocked(...)` did not check for allocation failures prior to this PR.
Instead the invalid memory address `(void *) -1` (`0xffffffffffffffff`) was passed to the caller as if it was a valid address.
After some operations the address is wrapped around from `0xffffffffffffffff` to `0x00000003ffdf` (`0xffffffffffffffff + 262112 == 0x00000003ffdf`);
The resulting address `0x00000003ffdf` is then written to.

fa2510d5c1 Use C++11 default member initializers (MarcoFalke)
Pull request description:
Changes:
* Remove unused constructors that leave some members uninitialized
* Remove manual initialization in each constructor and prefer C++11 default member initializers
This is not a stylistic change, but a change that avoids bugs such as:
* fix uninitialized read when stringifying an addrLocal #14728
* qt: Initialize members in WalletModel #12426
* net: correctly initialize nMinPingUsecTime #6636
* ...
