ZmnSCPxj 54cc735201 lightningd/peer_control.c: Implement waitblockheight. 
This is needed to fully implement handling of blockheight disagreements
between us and payee.
If payee believes the blockheight is higher than ours, then `pay`
should wait for our node to achieve that blockheight.

Changelog-Add: Implement `waitblockheight` to wait for a specific blockheight.

lightning-waitblockheight -- Command for waiting for blocks on the blockchain

SYNOPSIS

waitblockheight blockheight [timeout]

DESCRIPTION

The waitblockheight RPC command waits until the blockchain has reached the specified blockheight. It will only wait up to timeout seconds (default 60).

If the blockheight is a present or past block height, then this command returns immediately.

RETURN VALUE

Once the specified block height has been achieved by the blockchain, an object with the single field blockheight is returned, which is the block height at the time the command returns.

If timeout seconds is reached without the specified blockheight being reached, this command will fail.
