This fixes block parsing on testnet; specifically, non-standard tx versions. We hit a type bug in libwally (wallt_get_secp_context()) which I had to work around for the moment, and the updated libsecp adds an optional hash function arg to the ECDH function. Fixes: #2563 Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
