We have various functions to convert to a string, rename them all so we can count on fmt_X being the formatter for struct X, and make them all return `char *`. Sometimes they existed but were private, sometimes they had a different name. Most take a pointer, but simple types pass by copy: short_channel_id, amount_msat and amount_sat. The following public functions changed: 1. psbt_to_b64 -> fmt_wally_psbt. 2. pubkey_to_hexstr -> fmt_pubkey. 3. short_channel_id_to_str -> fmt_short_channel_id (scid by copy now!) 4. fmt_signature -> fmt_secp256k1_ecdsa_signature 5. fmt_amount_sat/fmt_amount_msat pass copy not pointer, return non-const char *. 6. node_id_to_hexstr -> fmt_node_id Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
