I am only making this change as it makes it simpler to do manual testing of CPFP-ing *local* txs.
That is, by changing a few easy-to-find lines of code, I can make the GUI allow CPFP-ing a local tx, but
without this change it errors out with "unknown fee for parent transaction".
If one has an incoming local tx saved in the wallet, adb.get_tx_fee(txid) returns None
(if the tx gets into the mempool, it will use the server-reported value instead).
In contrast, wallet.get_tx_info(tx).fee calls both wallet.get_wallet_delta(tx) and adb.get_tx_fee(txid),
making it more expensive but more complete.
On Android, we disallow screenshots on screens where the seed is visible.
(The seed is extremely sensitive data that should not be stored digitally without
significant precautions but it's also cumbersome to write down or memorise, so
some people instinctively just try to take a screenshot of it when creating a wallet.)
We do this by using the built-in OS mechanism of setting FLAG_SECURE on the window.
However, on some devices with custom ROMs (one report from LineageOS, one from /e/OS),
unsetting FLAG_SECURE crashes the application for some reason.
As a workaround, this commit adds a config setting into the Preferences,
to disable this mechanism and just always allow screenshots.
(note that you can get into the qml Preferences before creating/opening any wallet)

- risk_of_burning_coins_as_fees is turned into a private (helper) method, only called by check_sighash.
UIs should only care about check_sighash.
- check_sighash returns instance of new class "TxSighashDanger" instead of tuple
- made warning levels more fine-grained (FEE_WARNING_SKIPCONFIRM vs FEE_WARNING_NEEDCONFIRM)
- this became more complicated than I had hoped for but I think it is worth it to ~merge
check_sighash and risk_of_burning_coins_as_fees into one.

In the db, the 'seed_type' field could be present both at the top-level and inside keystores.
Note:
- both fields had usages
- the top-level field was added in 2.8 re "initial segwit support" (3a64ec0f2e)
- there was no db upgrade for it, so older files are missing it
- if present, valid values can be electrum types but also
other types supported by the wizard, e.g. "bip39"
- the keystore-level field was added in 4.1 (7b7bba2299)
- there was a db upgrade when it was introduced, so old files also have it
- if present, valid values can only be electrum types
- there is not much value in the top-level one having a non-electrum value,
and those values were never used by other parts of the code
- note that when creating a standard wallet from a bip39 seed, the seed is discarded.
Only the derived xprv and the derivation path are kept. If we changed this and also kept the seed,
e.g. to display it to the user, then it would make sense to save the seed type (e.g. "bip39").
However storing that seed_type would make more sense at the keystore level (not top-level).
We delete the top-level 'seed_type' field.
```
{
"keystore": {
"seed_type": "segwit",
...
},
"seed_type": "segwit",
...
}
```

Not sure why this a problem in the mac build but not in the windows build...
Also not sure why this only came up now -- was working before.
(I changed a few things in prev commits re the build scripts but I can't see the cause)
