New function is not currently called but will be called in upcoming commits. It
moves database path checking, and existence checking, and already-loaded
checking, and verification into a single function so this logic does not need
to be repeated all over higher level wallet code, and so higher level code does
not need to change when SQLite support is added in
https://github.com/bitcoin/bitcoin/pull/19077. This also lets higher level
wallet code make fewer assumptions about the contents of wallet directories.
This commit just adds the new function and does not change behavior in any way.
This removes a source of complexity and indirection that makes it harder to
understand path checking code. Path checks will be simplified in upcoming
commits.
There is no change in behavior in this commit other than a slightly more
descriptive error message in `loadwallet` if the default "" wallet can't be
found. (The error message is improved more in upcoming commit "wallet: Remove
path checking code from loadwallet RPC".)

This brings the behaviour of the import* calls closer to importmulti. After this change, the difference between importmulti and the other import* calls is
* that in importmulti you can "opt-out" of scanning early blocks by setting a later timestamp.
* that in importmulti the wallet will successfully import the data, but fail to rescan. Whereas in the other calls, the wallet will abort before importing the data.

65f3672f3b wallet: Refactor to use WalletLocation (João Barbosa)
01a4c095c8 wallet: Add WalletLocation utility class (João Barbosa)
Pull request description:
Advantages of this change:
- avoid resolving wallet absolute path and name repetitively and in multiple places;
- avoid calling `GetWalletDir` in multiple places;
- extract these details from the actual wallet implementation.
The `WalletLocation` class can be a way to represent a wallet not yet loaded that exists in the wallet directory.

The implementation of fs::relative resolves symlinks which is not intended
in ListWalletDir. The replacement does what is required, and listwalletdir
tests are fixed accordingly.
Also, building with boost 1.47 required 2 changes:
- replace fs::relative with an alternative implementation;
- fix fs::recursive_directory_iterator iteration.
Also warn if bitcoind is configured to use a relative -datadir path.
Specifying paths relative to the current working directory in a daemon process
can be dangerous, because files can fail to be located even if the
configuration doesn't change, but the daemon is started up differently.
Specifying a relative -datadir now adds a warning to the debug log. It would
not be backwards-compatible to forbid relative -datadir paths entirely, and it
could also be also inconvenient for command line testing.
Specifying a relative -walletdir now results in a startup error. But since the
-walletdir option is new in 0.16.0, there should be no compatibility issues.
Another reason not to use working directory paths for -walletdir specifically
is that the default -walletdir is a "wallets" subdirectory inside the datadir,
so it could be surprising that setting -walletdir manually would choose a
directory rooted in a completely different location.
