722c19ae93 lsp_plugin: add reversed feature-bit check
Core-Lightning returns the feature-bits in reversed order but we don't
want to rely on the caller to reverse the u8 slice themselfs. This
commit adds a convenience function that reverses the bitmap to avoid
hard to debug mistakes.

ce0be9dc87 lsp_plugin: remove redundant config option
We don't need to separately enable lsp and lsps2 services. If lsps2 is
not enabled what can we do with just the messaging layer?

7f3789b624 lsp_plugin: add htlc_accepted handler for no-mpp
Adds the service side (LSP) for a simple no-mpp trusted jit channel
opening. This is only an intermediate step, we are going to add support
for multiple htlcs.
This is experimental and can drain on-chain fees from the LSP if used in
public.

581eb3076f lsp_plugin: add lsps2_getinfo handler and call
This commit adds the lsps2_get_info call defined by BLIP052. It also
adds a test policy plugin that the LSP service plugin uses to fetch the
actual fee menu from to separate the concerns of providing a spec
compliant implementation of an LSP and making business decisions about
fee prices.

c52da76a57 lsp_plugin: add fn to wrap payload with peer id
We need to somehow access the peer id in the jrpc server to know where
the response should go. This seems to be the most convenient way for
now. We may unclutter this in the future if this results in performance
issues.
