This argument might have been used in the legacy wallets, but I don't
see any implementation using this argument in the SQLite wallets.
Removing it cleans up the code a bit.

Pull request description:
Currently, the migration process creates a brand-new descriptor wallet with no
connection to the user's legacy wallet when the legacy wallet lacks key material
and contains only watch-only scripts. This behavior is not aligned with user
expectations. If the legacy wallet contains only watch-only scripts, the migration
process should only generate a watch-only wallet instead.
TODO List:
* Explain that `migratewallet` renames the watch-only after migration, and
also that the wallet will not have keys enabled.

Instead of failing during initialization when encountering a legacy wallet, skip
loading the wallet and notify the user accordingly.
This allows users to access migration functionalities without needing to manually
remove the wallet from settings.json or resort to using the bitcoin-wallet utility.
This means that GUI users will be able to use the migration button, and bitcoin-cli
users will be able to call the migratewallet RPC directly after init.
Legacy wallets do not have the descriptors flag set. Don't load wallets
without the descriptors flag.
At the same time, we will no longer load BDB databases since they are
only used for legacy wallets.
Historically, the headers have been bumped some time after a file has
been touched. Do it now to avoid having to touch them again in the
future for that reason.

Implement ReadKey and HasKey of BerkeleyROBatch, and Next of BerkeleyROCursor.
Also adds the containers for records to BerkeleyRODatabase so that
BerkeleyROBatch will be able to access the records.
The wallet decryption process (CheckDecryptionKey() and Unlock())
contains an arg 'accept_no_keys,' introduced in #13926, that has
never been used.
Additionally, this also removes the unimplemented SplitWalletPath
function.
In order to get records beginning with a prefix, we will need a cursor
specifically for that prefix. So add a GetPrefixCursor function and
DatabaseCursor classes for dealing with those prefixes.
Tested on each supported db engine.
1) Write two different key->value elements to db.
2) Create a new prefix cursor and walk-through every returned element,
verifying that it gets parsed properly.
3) Try to move the cursor outside the filtered range: expect failure
and flag complete=true.

The fs.* files are already part of the libbitcoin_util library. With the
introduction of the fs_helpers.* it makes sense to move fs.* into the
util/ directory as well.
Next()'s result is a tri-state - failed, more to go, complete. Replace
the way that this is returned with an enum with values FAIL, MORE, and
DONE rather than with two booleans.
Instead of having DatabaseBatch deal with opening and closing database
cursors, have a separate RAII class that deals with those.
For now, DatabaseBatch manages DatabaseCursor, but this will change
later.
No change in behavior. Just remove a little bit of code, reduce macro usage,
remove duplicative functions, and make BDB and SQLite implementations more
consistent with each other.
This commit does not change to any code and behavior. It it is easily reviewed
with the --color-moved=dimmed_zebra git diff option.
Motivation for this change is to:
- Consolidate redundant functions
IsBDBFile /ExistsBerkeleyDatabase / SplitWalletPath, and
IsSQLiteFile / ExistsSQLiteDatabase in the next commits
- Detect SQLite wallets consistently regardless whether bitcoin is built with
SQLite support in the next commits
- Avoid attempting to open SQLite databases with the BDB library when bitcoin
is built without SQLite support in the next commits
We never need to open database in read-only mode as it's controlled
separately for every batch.
Also we can safely create database if it doesn't exist already
because require_existing option is verified in MakeDatabase
before creating a new WalletDatabase instance.
Although loadwallet() in rpcwallet.cpp assumes LoadWallet() always
assign some value to the 'status', but LoadWallet() does not do so
in some situation.
This fixes above and prevends loadwallet() returns ambiguous error code.
Checks are now consolidated in MakeBerkeleyDatabase function instead of
happening in higher level code.
This commit does not change behavior except for error messages which now
include more complete information.
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.
