We use feerate in several places, and each one really should react differently when it's not available (such as when bitcoind is still catching up): 1. For general fee-enforcement, we use the broadest possible limits. 2. For closingd, we use it as our opening negotiation point: just use half the last tx feerate. 3. For onchaind, we can use the last tx feerate as a guide for our own txs; it might be too high, but at least we know it was sufficient to be mined. 4. For withdraw and fund_channel, we can simply refuse. Fixes: #1836 Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
