42f474af18 wire: make lengths of variable fields implied by tal_count()
This is a much nicer interface, and works better in practice too.

b6a55a68ea tools/generate-wire.py: handle non-integer enum values.
BOLT 4 uses values like "PERM|1", so allow that.

2057de6d4f tools/generate-wire.py: Apparently OptionParser is deprecated, use argparse.
It is a bit nicer though.

8b72604d4d wire: allow #include directives in csv comments, and unknown structure types.
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'.

937a62100f generate-wire.py: allow optional typename in csv file.
For our internal CSV files, we can specify the type explicitly rather
than trying to guess (eg. bool).

8ad1298f88 generate-wire.py: add enum->name function.
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.

bdaa22e247 generate-wire.py: allow NULL len parameter from fromwire_*
It implies tal_count() gives the length. Great for almost all callers which
don't care if there are extra bytes.

e076d56709 generate-wire.py: include type bytes in towire/fromwire routines.
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.

3e044fdd62 generate-wire.py: allow comments.
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.

Sanity check that we're not streaming uninitialized bytes.

c864b28068 generate-wire.py: don't generate structures, hand in all values.
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.

We're going to want to use this for inter-daemon comms, so generalize it.
