The cause was that converting a block number to an scid truncates it
at 24 bits.  When we look through the index from (truncated number) to
(real end number) we get every channel, which is too large to encode,
so we iterate again.

This fixes both that problem, and also the issue that we'd end up
dividing into many empty sections until we get to the highest block
number.  Instead, we just tack the empty blocks on to then end of the
final query.

(My initial version requested 0xFFFFFFFE blocks, but the dev code
which records what blocks were returned can't make a bitmap that big
on 32 bit).

We have an incompatibility with lnd it seems: I've lost channels on

disable it for next release since I suspect it's our fault :(

And reenable the check which didn't work, for others to untangle.

I couldn't get option_data_loss_protect to be reliable, and I disabled
the check.  This was a mistake, I should have either spent even more
time trying to get to the bottom of this (especially, writing test
vectors for the spec and testing against other implementations).

Mark Beckwith 70707bf767 rpc: add check command
The check command allows us to check the parameters of a command
without running it. Example:

	lightning-cli check invoice 234 foo desc

We do this by removing the "command_to_check" parameter and then using the
remaining parameters as-is.

I chose the parameter name "command_to_check" instead of just "command" because
it must be unique to all other parameter names for all other commands. Why?
Because it may be ambiguous in the case of a json object, where the parameters are
not necessary ordered.  We don't know which one is the command to check and
which one is a parameter.

Rusty Russell e0d14bddb9 jsonrpc: allow multiple commands at once.
We now keep multiple commands for a json_connection, and an array of
json_streams.

When a command wants to write something, we allocate a new json_stream
at the end of the array.

We always output from the first available json_stream; once that
command has finished, we free that and move to the next.  Once all are
done, we wake the reader.

This means we won't read a new command if output is still pending, but
as most commands don't start writing until they're ready to write
everything, we still get command parallelism.

In particular, you can now 'waitinvoice' and 'delinvoice' and it will
work even though the 'waitinvoice' blocks.

Rusty Russell c5cd4791be onchaind: allow multiple candidate HTLCs for output match
When we have multiple HTLCs with the same preimage and the same CLTV,
it doesn't matter what order we treat them (they're literally
identical).  But when we offer HTLCs with the same preimage but
different CLTVs, the commitment tx outputs look identical, but the
HTLC txs are different: if we simply take the first HTLC which matches
(and that's not the right one), the HTLC signature we got from them
won't match.  As we rely on the signature matching to detect the fee
paid, we get:

	onchaind: STATUS_FAIL_INTERNAL_ERROR: grind_fee failed

So we alter match_htlc_output() to return an array of all matching
HTLC indices, which can have more than one entry for offered HTLCs.
If it's our commitment, we loop through until one of the HTLC
signatures matches.  If it's their commitment, we choose the HTLC with
the largest CLTV: we're going to ignore it once that hits anyway, so
this is the most conservative approach.  If it's a penalty, it doesn't
matter since we steal all HTLC outputs the same independent of CLTV.

For accepted HTLCs, the CLTV value is encoded in the witness script,
so this confusion isn't possible.  We nonetheless assert that the
CLTVs all match in that case.

Right now, the `config` file is read *after* the configuration working directory is moved to in the software. However one configuration option `lightning-dir` settable in the `config` file sets this working directory. As the directory is already opened (which defaults to `$HOME/.lightning`) before the configuration is read, the configured directory will not be used.

This patch parses the configuration file before opening the working directory, fixing this bug.
