We make it a first-class citizen internally, even though we won't use
it over the wire (at least, non-experimental builds). This scheme
follows the latest draft, in which features are flagged compulsory.
We also add several helper functions.
Since uses the *even* bits (as per latest spec), not the *odd* bits,
we have some other fixups.

We want to use this to handle the simple description for channel_type.
It also needs to handle variable-size types (just like subtypes).

This touches a lot of text, mainly to change "if `option_anchor_outputs`"
to "if `option_anchors`"

I wante to hide it inside the library, but it is good to have a single
place to verify that the client was permitted to send a message we are
handling, so make it officially part of the interface by prefixing it.
These are currently just shims that replicate the old behavior, but
when compiling as a library we can relink the status_* functions to
something that makes sense in the context of the user, and not assume
we're running as a subdaemon.
Just a security measure to avoid alternative use-cases of the hsmd
running into the issue that they need to send a `WIRE_HSMD_INIT`
message as first message. If that is not done, the `secretstuff` won't
get initialized and we'd be producing signatures from uninitialized
memory, which are completely useless.
Changelog-None: Internal change only
The fetchinvoice and offers plugins disable themselves if the option
isn't enabled (it's enabled by default on EXPERIMENTAL_FEATURES).

Changelog-Added: `experimental-offers` enables fetch, payment and creation of (early draft) offers.
This makes use of the constant defined in the previous commits to more
accurately detect plaintext, encrypted, and invalid seeds. We now error
on invalid seeds.
Changelog-changed: hsmd: we now error at startup on invalid hsm_secret
Changelog-changed: hsmtool: all commands now error on invalid hsm_secret
