Subject: Add some no-exporting of more offers code
X-Git-Url: http://git.bitcoin.ninja/index.cgi?a=commitdiff_plain;h=b7a63e3d97f829849c3f1c523b9e5c6e812d04b6;p=rust-lightning

Add some no-exporting of more offers code

These really could be handled in the bindings, but for lack of
immediate users there's not a strong reason to, so instead we just
disable them for now.
