This will help with the next patch, where we wean off using a global for features: connectd.c has access to the feature bits. Since connectd might now want to send a message, it needs the crypto_state non-const, which makes this less trivial than it would otherwise be. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
