a0ac5c276e status: API for status reporting. 
The API formalizes how daemons should report their statuses back to
the main lightningd.  It's a simple write API, which includes tracing
support (currently it always sends traces, later it could send iff
there's a failure, for example).

07fbeee29d coverage: Added coverage makefile target

bd6b9c377e coverage: Enable compilation with --coverage 
Setting the environment variable `COVERAGE=1` allows us to turn
coverage measurements on. This produces a number of auxiliary gcno and
gcda files which can then be converted into coverage reports.

I know line coverage and branch coverage is not a perfect metric, but
it might get us some more visibility into where more tests might be
needed.

9df0aa7538 libbase58: add autosubmodule rule, move depends to bitcoin/Makefile 
The object file should not be built inside the submodule, as that can
confuse git.

Not everything depends on the libbase58 header (CCAN doesn't), so
move that to the everything-else depends line.

The BITCOIN_SRC etc should also move to bitcoin/Makefile, but that's
a bigger change.

We add a "dev-restart" command which causes the daemon to close fds

that we always send a commit before newhtlc, because if not committed,
that is forgotten.  Fulfillhtlc and failhtlc get resent, since they're

The latest version of the BIP doesn't use inversion, but does use

It also uncovered a bug in the test scripts: the block timestamps
creep forward when we generate large numbers of blocks (UpdateTime
insists it be > GetMedianTimePast() so it's valid).  We need to take
this into account when waiting for the median to move (reduced it from
60 to 30 seconds, since that adds about 14 seconds).

ed3f0115d6 protocol: fix horribly thinko, keep own secrets. 
I had each side using the other side's hash secret.  That's a very
dumb idea, since it means you can steal from a unilateral close!

A's secret applies to A's commit transaction: it needs the
secret and B's final signature to steal funds, and that should
never happen (since A doesn't have the B's final signature, and
once A has given B the secret, they never broadcast the commit tx).

This makes the update a 4 step dance, since you need the new
revocation hash to make the other side's TX to sign.
