In functional tests it is a quite common scenario to generate fresh
elliptic curve keypairs, which is currently a bit cumbersome as it
involves multiple steps, e.g.:
privkey = ECKey()
privkey.generate()
privkey_wif = bytes_to_wif(privkey.get_bytes())
pubkey = privkey.get_pubkey().get_bytes()
Simplify this by providing a new `generate_keypair` helper function that
returns the private key either as `ECKey` object or as WIF-string
(depending on the boolean `wif` parameter) and the public key as
byte-string; these formats are what we mostly need (currently we don't
use `ECPubKey` objects from generated keypairs anywhere).
With this, most of the affected code blocks following the pattern above
can be replaced by one-liners, e.g.:
privkey, pubkey = generate_keypair(wif=True)
Note that after this commit, the only direct uses of `ECKey` remain in
situations where we want to set the private key explicitly, e.g. in
MiniWallet (test/functional/test_framework/wallet.py) or the test for
the signet miner script (test/functional/tool_signet_miner.py).

Pull request description:
Work decoupled from #25806, which cleanup and improves the Coin Selection flow further.
Adding the capability to propagate specific error messages from the Coin Selection process to the user.
Instead of always returning the general "Insufficient funds" message which is not always accurate to what happened internally.
Letting us instruct the user how to proceed under certain circumstances.
The following error messages were added:
1) If the selection result exceeds the maximum transaction weight,
we now will return:
-> "The inputs size exceeds the maximum weight. Please try sending
a smaller amount or manually consolidating your wallet's UTXOs".
2) If the user pre-selected inputs and disallowed the automatic coin
selection process (no other inputs are allowed), we now will
return:
-> "The preselected coins total amount does not cover the transaction
target. Please allow other inputs to be automatically selected or include
more coins manually".
3) The double-counted preset inputs during Coin Selection error will now
throw an "internal bug detected" message instead of crashing the node.
The essence of this work comes from several comments:

Pull request description:
The tests have several issues:
* Some tests that are wallet-type specific offer the option to run the test with the incompatible type
For example, `wallet_dump.py` offers `--descriptors` and on current master fails with `JSONRPCException: Invalid public key`. After the changes here, it fails with a clear error: `unrecognized arguments: --descriptors`.
* Tests that don't use the wallet at all offer the option to run it with a wallet type. This is confusing and wastes developers time if they are "tricked" into running the test for both wallet types, even though no wallet code is executed at all.
For example, `feature_addrman.py` will happily accept and run with `--descriptors` or `--legacy-wallet`. After the changes here, it no longer silently ignores the flag, but reports a clear error: `unrecognized arguments`.

Review note: The changes are complete, because self.options.descriptors
is set to None in parse_args (test_framework.py).
A value of None implies -disablewallet, see the previous commit.
So if a call to add_wallet_options is missing, it will lead to a test
failure when the wallet is compiled in.
so if there is an error in any of the pre-set coins, we can fail right away
without computing the wallet available coins set (calling `AvailableCoins`)
which is a slow operation as it goes through the entire wallet's txes map.
----------------------
And to make the Coin Selection flow cleared, have decoupled SelectCoins in two functions:
1) AutomaticCoinSelection.
2) SelectCoins.
1) AutomaticCoinSelection:
Receives a set of coins and selects the best subset of them to
cover the target amount.
2) SelectCoins
In charge of select all the user manually selected coins first ("pre-set inputs"), and
if coin_control 'm_allow_other_inputs=true', call 'AutomaticCoinSelection' to select a
subset of coins owned by the wallet to cover for the target - preset_inputs.total_amount
remaining value.
The external input test with specifying input weight would make a
pessimistic estimate of the input weight. However this would result in a
test failure as it is sometimes too pessimistic when an ECDSA signature
ends up being smaller than usual. To correct this, we can calculate the
input weight more accurately.
Added tests to rpc_fundrawtransaction, wallet_send, and rpc_psbt that
test that external inputs can be spent when input weight is provided.
Also tested that the input weight overrides any calculated weight.
Additionally, rpc_psbt's external inputs test is cleaned up a bit to be
more similar to rpc_fundrawtransaction's and avoid potential pitfalls
due to non-deterministic coin selection behavior.
The previous diff touched most files in ./test/, so bump the headers to
avoid having to touch them again for a bump later.

11d6459b6e rpc: include_unsafe option for fundrawtransaction (t-bast)
Pull request description:
Allow RPC users to opt-in to unsafe inputs when funding a raw transaction.
Applications that need to manage a complex RBF flow (such as lightning nodes using anchor outputs) are very limited if they can only use safe inputs.
I also added this option to `send` and `walletcreatefundedpsbt` who internally delegate to `fundrawtransaction`.

Fixes#21299
1) add a new sane "address" field (for outputs that have an
identifiable address, which doesn't include bare multisig)
2) with -deprecatedrpc: leave "reqSigs" and "addresses" intact
(with all weird/wrong behavior they have now)
3) without -deprecatedrpc: drop "reqSigs" and "addresses" entirely,
always.

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.
Create a fee_rate (sat/vB) RPC param and replace overloading the conf_target and
estimate_mode params in the following 6 RPCs with it:
- sendtoaddress
- sendmany
- send
- fundrawtransaction
- walletcreatefundedpsbt
- bumpfee
In RPC bumpfee, the previously existing fee_rate remains but the unit is changed
from BTC/kvB to sat/vB. This is a breaking change, but it should not be an
overly risky one, as the units change by a factor of 1e5 and any fees specified
in BTC/kvB after this commit will either be too low and raise an error or be 1
sat/vB and can be RBFed.
Update the test coverage for each RPC.

Pull request description:
Follow-up to #11413 providing a base to build on for #19543:
- bugfix for `bumpfee` raising a JSON error with explicit feerates, fixes issue #20219
- adds explicit feerate test coverage for `bumpfee`, `fundrawtransaction`, `walletcreatefundedpsbt`, `send`, `sendtoaddress`, and `sendmany`
- improves a few related RPC error messages and `ParseConfirmTarget()` / error message
- fixes/improves the explicit fee rate information in the 6 RPC helps, of which 2 were also missing `conf_target` sat/B units
This provides a spec and regression coverage for the potential next step of a universal `sat/vB` feerate argument (see #19543), as well as immediate coverage and minimum fixes for 0.21.
