Rusty Russell d8c06dccac global: expose all fmt_X functions for direct use, make uniform.
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
