Especially when we grind fees we may end up setting the fees several times, so
instead of always adding a new fee output look for an existing one and set its
value.

Elements requires us to have an explicit fee output instead of bitcoin's
implied fee. We add the fee output mostly after sorting the other outputs
since that matches the behavior in elements itself.

We are checking against chain-dependent constants, so let's make sure we are
using the ones for the correct chain.

We use to use the non-elements ones and then patch them manually. By using the
correct ones right from the start we have less work on our side.

Depending on the network we end up with different signature hash algorithms,
so we just collect that decision in one place.

If we are handling an elements transaction the value is not stored in the
satoshi field, rather it is stored in the `value` field which is prefixed with
a version (0x01) and is counted in `asset` units.

The header is not a contiguous section of memory in elements, and it is of
variable length, so the simple trick of hashing in-memory data won't work
anymore. Some of the datafields would have been wrong on big-endian machines
anyway, so this is better anyway.

This was a bit of trial and error due to libwally not liking hints when it
comes to length measurements, also the parsing bumps against a masking issue
in libwally that I'd following up on their issue tracker.

Since the difference between non-elements and elements block headers is just
the middle 2 fields, I split the old parsing code so I could add the middle
part.

Using a global variable is a bit lazy, but weaving the network type through
the entire stack is a daunting task. Maybe we can make that happen at a later
stage.
Most of the changes in `chainparams.c` are just formatting the
`genesis_blockhash` a bit nicer (`clang-format` to the rescue).

Since we will soon be writing the `liquid-regtest` section instead of the
`regtest` section we should make that configurable.

There were a few places we were rebuilding the config path by appending
`bitcoin.conf` to the bitcoin directory. So now we just remember it and
reference it instead.

This is the first step to transition to a better organized python module
structure. Sadly we can't reuse the `pylightning` module as a namespace module
since having importable things in the top level of the namespace is not
allowed in any of the namespace variants [1], hence we just switch over to the
`pyln` namespace. The code the was under `lightning` will now be reachable
under `pyln.client` and we add the `pyln.proto` module for all the things that
are independent of talking to lightningd and can be used for protocol testing.

This adapts the test to the new 'plugin' command: no more sleeping,
since we are synchronous !
This tests the timeout by increasing the 'slowinit' plugin sleep
duration at init reception.
This adds a broken plugin to make sure we won't crash because of a
misbehaving plugin (unmet dependency is the most common case).
And make a function for the 'rescan' subcommand so that we are
consistent and have only subcommand logic in the main function,
which return command_still_pending() in any case (but 'stop').
