This lets us marshal and unmarshal undefined complex types; the fromwire
function will allocate it for us, so we don't even need to know the size.
This turns out to be really nice for marshalling 'struct crypto_state'.

For our internal CSV files, we can specify the type explicitly rather
than trying to guess (eg. bool).

Pretty! Takes an int instead of the enum directly, because in the
main daemon we call it via a function pointer, so want them all the
same type.

It implies tal_count() gives the length. Great for almost all callers which
don't care if there are extra bytes.

This removes some redundancy in creating messages, but also allows
a lazy form or parsing without explicitly checking the type.
A helper fromwire_peektype() is added to look up the type and handle
the too-short-for-type problem.

We emit them into the generated code at appropriate points, but it
would be better if we simply preserved the order they were given in.

This is a bit more awkward for large structures, but avoids
indirection for the simpler ones (I copied the structures for the test
code, however). We also remove explicit padding.
