f45d962a14 channeld: implement and refine fee-related functions.
We had some in the header, now implement them, and add a channel_feerate()
accessor.

f1e4cad9d4 feerate: use u32 everywhere.
The wire protocol uses this, in the assumption that we'll never see feerates
in excess of 4294967 satoshi per kiloweight.

So let's use that consistently internally as well.

7151c65535 chaintopology: track three different feerates.
Depending on what we're doing, we can want different ones.  So use
IMMEDIATE (estimatesmartfee 2 CONSERVATIVE), NORMAL (estimatesmartfee
4 ECONOMICAL) and SLOW (estimatesmartfee 100 ECONOMICAL).

If one isn't available, we try making each one half the previous.

40315bfb91 test: fix dependencies.
Test objects must be added to $(ALL_OBJS) so they correctly depend on
CCAN headers etc.

Also, each test in a subdir must depend on headers and src in the parent
directory, as it will often #include them directly.

9b42f49d2c onchaind: fix feerate determination.
There were two bugs here.  First, grind_feerate() needs to check the
actual range of feerates, not the same rate over and over!  Secondly,
we need to grind the feerate for the HTLC-success tx, too.

These were masked by the fact that our tests always use the same feerate!

71c090745b channel: Defer sending the announcement_signature until both lock
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.
