Rusty Russell 795e42d757 chaintopology: fix use-after-free which sometimes causes fatal() in clear_otx_peer
I've only seen this under travis, so I can't verify that this fixes it,
but it's certainly a bug which could cause that issue.

Rusty Russell 0f97b8cf36 subdaemon.c: subdaemon_setup() routine for all daemons.
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.

Christian Decker ce845853b0 hsm: Generate fully signed transactions and return them to caller
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.

Christian Decker 248879e203 wire: Move bitcoin_tx serialization from htlc_wire to wire
Removes the need to keep a second transaction around and marking it as

Christian Decker 524849bc11 bitcoin: Split pull_bitcoin_tx
The deserialization of bitcoin transactions in wire/ is rather
annoying in that we first allocate a new bitcoin_tx, then copy it's
contents onto the destination and then still carry the newly allocated
one around due to the tal-tree. This splits `pull_bitcoin_tx` into
two: one part that does the allocation and another one that proceeds
to parse.

Rusty Russell 824f8517ac onchaind: fix all_irrevocably_resolved test.
I was examining a test_onchain_timeout failure, and realized that we
were forgetting a peer even though we'd just spent the HTLC_TIMEOUT_TX!

This reveals that we weren't resolving an output when we stole the preimage
from it, like we should.

Rusty Russell fb81e6c14b chaintopology: always start 100 blocks back.
Since we panic when we see our root reorg out, even if we're not doing
anything yet, restoring the 100 block margin is the simplest fix.

Unfortunately this means adding a 100-block spacer in the tests, so things
don't get confused.

Rusty Russell 93c589efe8 wallet: save block height when we first create channel.
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).
