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).

To fix this, we actually make 'ld->timers' a pointer, so we can clean
it up last of all. We can't free it before ld, because that causes
timers to be destroyed.

We didn't wait until l2 processed the final state of HTLC #2, so it might not include it when it drops onchain, leading to us only getting 3 (not 4) sendrawtx calls. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

The variable `block` (instace of `struct block`) is
allocated on the stack without being initialized, i.e. its
member `prev` points to nowhere. This causes a segmentation
fault on my machine on the binding of "prev_hash" on running
`wallet_block_add`, as the following core-dump analysis
shows:
$ egdb ./wallet/test/run-wallet ./run-wallet.core
[...]
Core was generated by `run-wallet'.
Program terminated with signal SIGSEGV, Segmentation fault.

leaving secp256k1_ctx as NULL.

location was leaking memory.
