This removes the dependency on OpenSSL for the interaction tests, by providing a pure-Python
toy implementation of secp256k1.

I also moved some RPC methods that were not at the end of the file with
the other ELEMENTS RPC methods. This makes the diff on my machine look
crazy. Let's hope GitHub has more intelligent diffs..

Pull request description:
When starting a test, we are always in IBD because the timestamps on cached blocks are in the past. Usually, we solve that by generating a block at the beginning of the test.
That is clumsy and might even lead to other problems such as #15360 and https://github.com/bitcoin/bitcoin/issues/14446#issuecomment-461926598
So fix that by getting rid of mocktime and always refreshing the last block of the cache when starting the test framework.
Should fix#14446

Previously we'd report "0", which could be mistaken for a valid number. E.g. the number of transactions is 0 or the block weight is 0, whatever that means.

13782b8ba8 docs: add perf section to developer docs (James O'Beirne)
58180b5fd4 tests: add utility to easily profile node performance with perf (James O'Beirne)
Pull request description:
Adds a context manager to easily (and selectively) profile node performance during functional test execution using `perf`.
While writing some tests, I encountered some odd bitcoind slowness. I wrote up a utility (`TestNode.profile_with_perf`) that generates performance diagnostics for a node by running `perf` during the execution of a particular region of test code.
`perf` usage is detailed in the excellent (and sadly unmerged) https://github.com/bitcoin/bitcoin/pull/12649; all due props to @eklitzke.
### Example
```python
with node.profile_with_perf("large-msgs"):
for i in range(200):
node.p2p.send_message(some_large_msg)
node.p2p.sync_with_ping()
```
This generates a perf data file in the test node's datadir (`/tmp/testtxmpod0y/node0/node-0-TestName-large-msgs.perf.data`).
Running `perf report` generates nice output about where the node spent most of its time while running that part of the test:
```bash
$ perf report -i /tmp/testtxmpod0y/node0/node-0-TestName-large-msgs.perf.data --stdio \
| c++filt \
| less
# To display the perf.data header info, please use --header/--header-only options.

When running tests with --usecli, unify the conversion from argument objects to
strings using a new function arg_to_cli(). This fixes boolean arguments when
using named arguments.
Also use json.dumps() to get the string values for arguments that are dicts and
lists so that bitcoind's JSON parser does not become confused.
3c3e31c3a4 [tests] Add wallet-tool test (João Barbosa)
49d2374acf [tools] Add wallet inspection and modification tool (Jonas Schnelli)
Pull request description:
Adds an offline tool `bitcoin-wallet-tool` for wallet creation and maintenance.
Currently this tool can create a new wallet file, display information on an existing wallet, and run the salvage and zapwallettxes maintenance tasks on an existing wallet. It can later be extended to support other common wallet maintenance tasks.
Doing wallet maintenance tasks in an offline tool makes much more sense (and is potentially safer) than having to spin up a full node.
