So far we have been generating the tx both in the HSM and in the
caller, and had to rely on them generating exactly the same
transaction. This makes it a lot simpler by fully signing and
serializing the TX on the HSM side and the caller just needs to unpack
and broadcast it.

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

This gives us a lower bound on where funding tx could be.
In theory, it could be lower than this if we get a reorganization, but
in practice this is already a 1-block buffer (since we can't get into
current block, only the next one).

It's only used for tests, but it's better to use the wallet_channels_load_active like
the real code.

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_txid_to_hex() so it's reversed as people expect.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
I prefer the typesafety of specific functions, rather than having the
caller know that txids are traditionally reversed in bitcoin.
And we already have a bitcoin_txid_to_hex() function for this.

It looks like we were missing the address on insert into the peers table. This
will insert the address formatted by fmt_wireaddr. This happens to include the
ip and port.
This is fine, since parse_wireaddr has been updated to parse ports in ip address
strings.

* 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.

Accuracy improvements:
1. We assumed the output was a p2wpkh, but it can be user-supplied now.
2. We assumed we always had change; remove this for wallet_select_all.
Calculation out-by-one fixes:
1. We need to add 1 byte (4 sipa) for the input count.
2. We need to add 1 byte (4 sipa) for the output count.
3. We need to add 1 byte (4 sipa) for the output script length for each output.
4. We need to add 1 byte (4 sipa) for the input script length for each input.
5. We need to add 1 byte (4 sipa) for the PUSH optcode for each P2SH input.
The results are now a slight overestimate (due to guessing 73 bytes
for signature, whereas they're 71 or 72 in practice).

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.

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.

jsonrpc handlers usually directly call command_success or
command_fail; not doing that implies they're waiting for something
async.
Put an explicit call (currently a noop) there, and add debugging
checks to make sure it's used.

bitcoin_from_base58 returns a testnet flag, but json_withdraw
did not actually check it. Add a basic check that the given
withdraw address belongs to the same net lightningd is using.
Change all calls to use the correct serialization and deserialization
functions, include the correct headers and remove the control
messages.

The filter is being populated while initializing the daemon and by
adding new keys as they are being generated. The filter is then used
in connect_block to identify transactions of interest.
