A check to raise an error on zero-fee txns was mistakenly extended in commit
a0d4957 from the bumpfee and send{toaddress, many} RPCs to also include
fundrawtransaction and walletcreatefundedpsbt.
This commit overrides zero fee rate checking for these two RPCs, not only for
the feeRate (BTC/kvB) arg to return to previous behavior, but also for the new
fee_rate (sat/vB) arg.

It is unnecessary to upgrade to FEATURE_HD_SPLIT if this feature is
already supported by the wallet. Because upgrading to FEATURE_HD_SPLIT
actually requires upgrading to FEATURE_PRE_SPLIT_KEYPOOL, users would
accidentally be upgraded to FEATURE_PRE_SPLIT_KEYPOOL instead of nothing
being done.

Pull request description:
This PR builds on #11413 and #20220 to address #19543.
- replace overloading the conf_target and estimate_mode params with `fee_rate` in sat/vB in the sendtoaddress, sendmany, send, fundrawtransaction, walletcreatefundedpsbt, and bumpfee RPCs
- allow non-actionable conf_target value of `0` and estimate_mode value of `""` to be passed to use `fee_rate` as a positional argument, in addition to as a named argument
- fix a bug in the experimental send RPC described in https://github.com/bitcoin/bitcoin/pull/20220#discussion_r513789526 where args were not being passed correctly into the options values
- update the feerate error message units for these RPCs from BTC/kB to sat/vB
- update the test coverage, help docs, doxygen docs, and some of the RPC examples
- other changes to address the excellent review feedback

b6121edf70a8d50fd16ddbba0c3168e5e49bfc2e swapped "is" for "==" in literal comparison (Tyler Chambers)
Pull request description:
In Python 3.8+ literal comparisons using "is" instead of "==" produce a SyntaxWarning [source](https://docs.python.org/3.8/whatsnew/3.8.html#changes-in-python-behavior).
I checked the entire devtools directory, this seems to be the only occurrence.
This is a small fix, but removes the SyntaxWarning.

Pull request description:
This PR cleans up the wallet upgrade mechanism a bit, fixes some probably bugs, and adds more test cases.
The `nWalletMaxVersion` member variable has been removed as it made `CanSupportFeature` unintuitive and was causing a couple of bugs. The reason this was introduced originally was to allow a wallet upgrade to only occur when the new feature is first used. While this makes sense for the old `-upgradewallet` option, for an RPC, this does not quite make sense. It's more intuitive for an upgrade to occur if possible if the `upgradewallet` RPC is used as that's an explicit request to upgrade a particular wallet to a newer version. `nWalletMaxVersion` was only relevant for upgrades to `FEATURE_WALLETCRYPT` and `FEATURE_COMPRPUBKEY` both of which are incredibly old features. So for such wallets, the behavior of `upgradewallet` will be that the feature is enabled immediately without the wallet needing to be encrypted at that time (note that `FEATURE_WALLETCRYPT` indicates support for encryption, not that the wallet is encrypted) or for a new key to be generated.
`CanSupportFeature` would previously indicate whether we could upgrade to `nWalletMaxVersion` not just whether the current wallet version supported a feature. While this property was being used to determine whether we should upgrade to HD and HD chain split, it was also causing a few bugs. Determining whether we should upgrade to HD or HD chain split is resolved by passing into `ScriptPubKeyMan::Upgrade` the version we are upgrading to and checking against that. By removing `nWalletMaxVersion` we also fix a bug where you could upgrade to HD chain split without the pre-split keypool.
`nWalletMaxVersion` was also the version that was being reported by `getwalletinfo` which meant that the version reported was not always consistent across restarts as it depended on whether `upgradewallet` was used. Additionally to make the wallet versions consistent with actually supported versions, instead of just setting the wallet version to whatever is given to `upgradewallet`, we normalize the version number to the closest supported version number. For example, if given 150000, we would store and report 139900.
Another bug where CHDChain was not being upgraded to the version supporting HD chain split is also fixed by this PR.
Lastly several more tests have been added. Some refactoring to the test was made to make these tests easier. These tests check specific upgrading scenarios, such as from non-HD (version 60000) to HD to pre-split keypool. Although not specifically related to `upgradewallet`, `UpgradeKeyMetadata` is now being tested too.
Part of the new tests is checking that the wallet files are identical before and after failed upgrades. To facilitate this, a utility function `sha256sum_file` has been added. Another part of the tests is to examine the wallet file itself to ensure that the records in the wallet.dat file have been correctly modified. So a new `bdb.py` module has been added to deserialize the BDB db of the wallet.dat file. This format isn't explicitly documented anywhere, but the code and comments in BDB's source code in file `dbinc/db_page.h` describe it. This module just dumps all of the fields into a dict.
