We force use of tal_wally_start/tal_wally_end around every wally
allocation, and with "end" make the caller choose where to reparent
everything.
This is particularly powerful where we allocate a tx or a psbt: we
want that tx or psbt to be the parent of the other allocations, so
this way we can reparent the tx or psbt, then reparent everything
else onto it.
Implementing psbt_finalize (which uses a behavior flag antipattern)
was tricky, so I ended up splitting that into 'psbt_finalize' and
'psbt_final_tx', which I think also makes the callers clearer.

At least on my Ubuntu box, they're compatible. If they're not, we need
to disable regeneration altogether.

These are simple space-separated key-value pair sets of options instead of the
URI style DSNs, but they are also much more flexible allowing the user to
specify client SSL certificates, server certificates, compression and
encryption levels, and much more (see [1] for more information)

Changelog-Added: db: Added support for key-value DSNs for postgresql, allowing for a wider variety of configurations and environments.
wallet_commit_channel would fill in the old_remote_per_commit and
fee_states, which is weird since the caller doesn't care.
Make the caller set all the channel_info fields, so wallet_commit_channel
is a simple consumer.

If we've already got a scriptSig field filled out for a PSBT input, we
use that instead of 'deriving' the scriptSig from the redeemscript
(finalizing a PSBT removes the redeemscript field)
Several times we had issues with plugins not being able to re-encode an RPC
result because they forgot to use the custom encoder class. This allows us to
patch the JSONEncoder when we start the RPC or the plugin and automagically
support classes that provide a `to_json` method.
I mistakenly assumed the block would be freed after processing completed. That
is not true since chaintopology keeps headers and stubs around for reorgs. So
we need to remove the precomputed txids along with the full_txs.
1. Rename memleak_enter_allocations to memleak_find_allocations.
2. Unify scanning for pointers into memleak_remove_region / memleak_remove_pointer.
3. Document the functions.

This is because there is uninitialized padding at the end of struct
peer_state.

They previously prevented any child from being detected as leaks, now
they just mark the tal allocation itself as not being a leak.
