We were sending the announcement_signatures as soon as we locally
locked and got the announcement_depth, this doesn't make the channel
usable any sooner and forces the other side to stash the
signature. This defers the announcement_signature until the channel
really is usable.
This is done by adding an additional check for the remote locked
message and adding a trigger on remote lock.

Thought we don't handle it at the moment, nodes can certainly have multiple

We don't track them accurately when in onchaind, but we don't want to:
onchaind can be restarted at any time.
Once it's all settled, we're clear to clean them up.

We are announcing that we are willing to accept incoming payments with
current_height + min_final_cltv_expiry + slack, assuming that the
sender adds some slack. In particular we'd reject the payment if
slack=0 which is allowed by the spec.

Raising the exception about non-zero exit values into the
teardown. This was previously masking the valgrind errors. Now
valgrind errors > crash errors > non-zero return value.
Still hoping to catch that elusive [7, 0] return value on travis.

With the previous commit this enables py.test on travis, which should
give us some better way of hunting down bugs on travis.

The py.test unit test runner offers a number of more advanced features
than simply running using unittest.main. In particular it allows us to
capture a tests output and print it if it fails. This change checks
whether we have pytest available and if yes, enables verbose tests and
runs using pytest. This'll give the usual experience (with colors!)
and show us the stdout if a test fails making travis a lot easier to
handle.

If a structure foo has a optional fields opt1 and opt2, this creates
towire_foo, towire_foo_opt1 and towire_foo_opt2 (since opt2 implies opt1),
similarly for fromwire_*.
This requires the callers to be updated to call the correct routines (eg.
try fromwire_foo_opt2, then fromwire_foo_opt1, then finally fromwire_foo),
but this is a minimal change to the generation code.

We save location where transaction was started, in case we try to nest.
There's now no error case; db_exec_mayfail() is the only one.
This means the tests need to override fatal() if they want to intercept
these errors.

We're going to be always in a transaction soon.
Note the rollback we used to do was an optimization: the utxo destructors
would already clean up the new UTXOs in the database.

we should never be doing two startups at once, but why take chances? Plus,
we can then assert that all db calls are in transactions.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This is the only case where we actually rely on the db to ensure we don't
do something twice: don't error out if it fails.

Otherwise we find ourselves outside a commitment. This is a bandaid
until we remove nested commitments again at the end of this series.

Nesting is provided by only actually performing the outermost
transaction and simulating the nested ones. This still allows us to
ensure on lower levels that we are in the context of a transaction
without having to resort to keeping explicitly track of it in the
calling code.

This is a subset of a "bitcoind: wrap callbacks in transaction." from
the everything-in-transaction branch, but we need the ld pointer now.

ie. non-printable, quotes or escapes. We allow these outside tokens
(we expect tabs and \n for example).
This is a big hammer, but if someone really wants we can add support
later.

Don't try to escape them. It's whack-a-mole and they shouldn't do it anyway.

And nail "make check-source" to that specific version (which is a commit id,
not a branch name, so needs a different syntax for git).
