permute_outputs is sometimes called with empty arguments from initial_commit_tx.
Make sure we guard against that case. We also do the same in permute_inputs for
good measure.

Our handling of SIGPIPE was incoherent and inconsistent, and we had much
cut & paste between the daemons. They should *ALL* ignore SIGPIPE, and
much of the rest of the boilerplate can be shared, so should be.

Removes the need to keep a second transaction around and marking it as
`noleak`, just to make sure that dependencies are not free'd along
with the original tx.

The close_info is needed to re-derive the secret key that is supposed
to be used to sign the input spending the output.

This is necessary to grad the their_unilateral/to-us outputs since
they aren't being harvested by `onchaind`

The use of status_failed() requires a stubs update, which fails
with unnamed parameters, so tweak the status.h header as well.

It's just a sha256_double, but importantly when we convert it to a
string (in type_to_string, which is used in logging) we use
bitcoin_blkid_to_hex() so it's reversed as people expect.

Correctly format ipv6 address with ports. This will also make it more compatible
with the new parse_wireaddr, which has been updated to parse ports. They are
inverses now.
Also add some tests that check this.

* Add port parsing support to parse_wireaddr. This is in preparation for storing
addresses in the peers table. This also makes parse_wireaddr a proper inverse of
fmt_wireaddr.
* Move parse_wireaddr to common/wireaddr.c this seems like a better place for
it. I bring along parse_ip_port with it for convenience. This also fixes some
issues with the upcoming ip/port parsing tests.

We were using changekey as the flag to produce change, not changesat,
but the caller was using changesat as the flag.
Also, don't allocate changekey at all if we don't need it; this means
valgrind will complain if we use it at all, too.

Two changes:
- Fixed the function signature of noleak_ to match in both
configurations
- Added memleak.o to linker for tests
Generating the stubs for the unit tests doesn't really work since the
stubs are checked in an differ between the two configurations, so
adding memleak to the linker fixes that, by not requiring stubs to be
generated in the first place.

We create a temporary tx which is a child of the real tx, for simplicity of
marshalling. That's OK.

In particular, the pay command attaches all kinds of stuff to the
struct command; they're not really a leak, since commands expire.

This is not a child of cmd, since they have independent lifetimes, but
we don't want to noleak them all, since it's only the one currently in
progress (and its children) that we want to exclude.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
It's a single, full-lifetime allocation; make sure we only exclude that
one, though this is fragile: tests will break if it moves.

We use the tal notifiers to attach a `backtrace` object on every
allocation.
This also means moving backtrace_state from log.c into lightningd.c, so
we can hand it to memleak_init().
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This is a primitive mark-and-sweep-style garbage detector. The core is
in common/ for later use by subdaemons, but for now it's just lightningd.
We initialize it before most other allocations.
We walk the tal tree to get all the pointers, then search the `ld`
object for those pointers, recursing down. Some specific helpers are
required for hashtables (which stash bits in the unused pointer bits,
so won't be found).
There's `notleak()` for annotating things that aren't leaks: things
like globals and timers, and other semi-transients.

On unmarshal, we stop unmarshaling on a 0 (ADDR_TYPE_PADDING) type. So
we should also stop marshaling in that case.
