The largest change is inside hsmd: it hands a null per-commitment key
to the wallet to tell it to spend the to_remote output.
It can also now resolve unknown commitments, even if it doesn't have a
possible_remote_per_commitment_point from the peer.

Somehow this change got lost, but it's needed for option_static_remotekey,
to quote gen_peer_wire_csv:
msgtype,channel_reestablish,136
msgdata,channel_reestablish,channel_id,channel_id,
msgdata,channel_reestablish,next_commitment_number,u64,
msgdata,channel_reestablish,next_revocation_number,u64,

As per BOLT02 #message-retransmission :
if `next_commitment_number` is 1 in both the `channel_reestablish` it sent and received:
- MUST retransmit `funding_locked`
This moves field initialization into plugins_new(), and
adds a memleak helper to search the request map:

It seems we spend a lot of time waiting for `bitcoind` and `lightningd` to
talk to disks. This adds the `TEST_DIR` environment variable, allowing for
example to use `/dev/shm`, or a faster disk than the disk `/tmp` is on, as the
root directory for all test-related files.
Testing this on one of our builder machines cut the time to run the entire
suite under valgrind roughly in half (180-200 seconds vs 440-490 seconds).
My machine would accumulate a number of zombie lightningd and bitcoind
processes over time while testing. Investigating this showed that if a fixture
raised an exception during fixture teardown then other fixtures that have not
been torn down would linger around. The issue is that pytest treats exceptions
in fixtures as non-recoverable and therefore will not catch them and call the
remaining ones.
This commit adds a new fixture, that is there just to collect eventual errors
from other fixtures and ensure that anything that needs to clean up something,
e.g., processes started by the fixture, are cleaned up before we raise an
eventual exception. This is achieved by making any fixture that needs cleaning
up dependent on the teardown_checks fixture, which also serves as central
point to collect errors and printer of eventual errors.

If they don't send us a gossip timestamp filter, we won't be sending
them any gossip, thus won't be aging the gossip_rcvd_filter. So
restrict it to 10,000 elements just to be sure.

Use the same "child of tal object" trick to mark things "notleak".
That simplifies things and means we don't have to track them being
reallocated.

Rather than reaching into data structures, let them register their own
callbacks. This avoids us having to expose "memleak_remove_xxx"
functions, and call them manually.
Under the hood, this is done by having a specially-named tal child of
the thing we want to assist, containing the callback.

`make update-mocks` is usually run in DEVELOPER mode, but then it includes
definitions for functions which aren't declared in non-DEVELOPER mode.
We hacked this in a few places, but it's fragile, and worst, now we
have EXPERIMENTAL_FEATURES as well, it's complex.
Instead, declare developer-only functions (but don't define them).
This is a bit more awkward if you accidentally use one in
non-DEVELOPER code (link error rather than compile error), but makes
autogenerating test mocks much easier.

We're about to remove them.
Includes fix to sqlite3_bind_short_channel_id to not assume `id` is a
tal object.
