Remove sync verification
The default sync verification is removed from wallet module.
By default sync time verification only makes sense for `electrum` and
`esplora` backend as they are usually untrusted 3rd party services.
script verification for transaction is costly, so removing default
script verification optimizes performance.
Merge the 0.16.0 release branch back into the master branch.

This PR aims to fix #472 . We can retrieve the dust value for a given ``bitcoin::blockdata::script::Script``, so I adjusted the ``is_dust`` function within the ``IsDust`` trait to receive such a ``&Script``. Thus, the ``is_dust`` function can make the proper comparison.
Let me know if you think that there could be a better interface than this.
Furthermore, because this new ``is_dust`` function provides a tighter upper bound on Bitcoin Core's ``GetDustThreshold()``, it actually invalidated a test. In the test, the drain output for a transaction was no longer considered dust and no longer included in the fee. Instead, the drain output was kicked back to the sender, invalidating the asserts in line 3436, 3437 and 3441 in ``src/wallet/mod.rs``. I increased the ``FeeRate`` in the test just enough that the drain output would be small enough to considered dust again and included in the total fee.

By default, reqwest uses openssl for TLS. Any consumer wanting to use
rustls will thus pull in unnecessary dependencies.

Disable reqwest's default features
By default, reqwest uses openssl for TLS. Any consumer wanting to use
rustls will thus pull in unnecessary dependencies. To make getting started
with bdk and reqwest easier, we add a `reqwest-default-tls` feature
that can be used to activate reqwest's `default-tls` feature. TLS is
necessary for the esplora integration. Adding this feature makes it possible
for people to use bdk with esplora without adding a reqwest dependency to
their manifest.

Merge bitcoindevkit/bdk#471: moving the function wallet_name_from_descriptor from blockchain/rpc.rs to wallet/mod.rs as it can be useful not only for rpc
2fc81141806ace8f12e5a019c0866f16fa8a02dc moving the function wallet_name_from_descriptor from blockchain/rpc.rs to wallet/mod.rs as it can be useful not only for rpc (Richard Ulrich)
Pull request description:
### Description
Moving the function wallet_name_from_descriptor from rpc.rs to mod.rs
Since the local cache for compact filters should be separate per wallet, this function can be useful not only for rpc.
### Notes to the reviewers
I thought about renaming it, but waited for opinions on that.

This PR does dependency inversion on the previous sync logic for electrum and esplora captured in the trait `ElectrumLikeSync`. This means that the sync logic does not reference the blockchain at all. Instead the blockchain asks the sync logic (in `script_sync.rs`) what it needs to continue the sync and tries to retrieve it.
The initial purpose of doing this is to remove invocations of `maybe_await` in the abstract sync logic in preparation for completely removing `maybe_await` in the future. The other major benefit is it gives a lot more freedom for the esplora logic to use the rich data from the responses to complete the sync with less HTTP requests than it did previously.
## List of changes
- sync logic moved to `script_sync.rs` and `ElectrumLikeSync` is gone.
- esplora makes one http request per sync address. This means it makes half the number of http requests for a fully synced wallet and N*M less requests for a wallet which has N new transactions with M unique input transactions.
- electrum and esplora save less raw transactions in the database. Electrum still requests input transactions for each of its transactions to calculate the fee but it does not save them to the database anymore.
- The ureq and reqwest blockchain configuration is now unified into the same struct. This is the only API change. `read_timeout` and `write_timeout` have been removed in favor of a single `timeout` option which is set in both ureq and reqwest.
- ureq now does concurrent (parallel) requests using threads.
- An previously unnoticed bug has been fixed where by sending a lot of double spending transactions to the same address you could trick a bdk Esplora wallet into thinking it had a lot of unconfirmed coins. This is because esplora doesn't delete double spent transactions from its indexes immediately (not sure if this is a bug or a feature). A blockchain test is added for this.
- BONUS: The second commit in this PR fixes the feerate calculation for esplora and adds a test (the previous algorithm didn't work at all). I could have made a separate PR but since I was touching this file a lot I decided to fix it here.
## Notes to the reviewers
- The most important thing to review is the the logic in `script_sync.rs` is sound.
- Look at the two commits separately.
- I think CI is failing because of MSRV problems again!
- It would be cool to measure how much sync time is improved for your existing wallets/projects. For `gun` the speed improvements for modest but it is at least hammering the esplora server much less.
- I noticed the performance of reqwest in blocking is much worse in this patch than previously. This is because somehow reqwest is not re-using the connection for each request in this new code. I have no idea why. The plan is to get rid of the blocking reqwest implementation in a follow up PR.

Fix blockchain_tests::test_send_to_bech32m_addr
Now works with latest released versions of rust-bitcoincore-rpc and
bitcoind. Once these crates are updated to support creating descriptor
wallets and add importdescriptors and bech32m support this test will
need to be updated.
