the original version of the subtype generator emitted '$'
to designate that a field was a subtype; now it's got a different
format:
funding_type,8,num_inputs,2
funding_type,10,input_info,num_inputs*input_info
this patch updates our generator to understand this new format
This is needed so that some csv's can expose their subtype parsing
functions in their header. This gets used in a later PR where
we start replacing manually created 'subtype' definitions with
generated ones.
This doesn't result in a speedup for our benchmark, since we use the
cli tool which does the formatting.

Outputs CSV. We add some stats for load times in developer mode, so we can
easily read them out.
peer_read_all_sec doesn't work, since we seem to reject about half the
updates for having bad signatures. It's also very slow...
routing fails, for unknown reasons, so that failure is ignored in routing_sec.

fixup printing methods in devtools/decodemsg such that TLV's can
now be printed as well. here's how you'd use it:
$ ./devtools/decodemsg --tlv opening_tlv 0120001E020202020202020202020202020202020202020202020202020202020202

TLV's use var_int's for messages sizes, both internally and
in the top level (you should really stack a var_int inside a var_int!!)
this updates our automagick generator code to understand 'var_ints'
passing back a null TLV was crashing here, because we tried to
dereference a null pointer. instead, we put it into a temporary
struct that we can check for NULL-ness, before assigning to the
passed in pointer.
let's let the fromwire__tlv methods allocate the tlv-objects and
return them. we also want to initialize all of their underlying
messages to NULL, and fail if we discover a duplicate mesage type.
if parsing fails, instead of returning a struct we return NULL.
Suggested-By: @rustyrussell
Since messages in TLV's are optional, the ideal way to deal with
them is to have a 'master struct' object for every defined tlv, where
the presence or lack of a field can be determined via the presence
(or lack thereof) of a struct for each of the optional message
types.
In order to do this, appropriately, we need a struct for every
TLV message. The next commit will make use of these.
Note that right now TLV message structs aren't namespaced to the
TLV they belong to, so there's the potential for collision. This
should be fixed when/where it occurs (should fail to compile).
Add tlv-messages to the general messages set so that their parsing
messages get printed out.
FIXME: figure out how to account for partial message length processing?
Version 1.1 of the lightning-rfc spec introduces TLVs for optional
data fields. This starts the process of updating our auto-gen'd
wireformat parsers to be able to understand TLV fields.
The general way to declare a new TLV field is to add a '+' to the
end of the fieldname. All field type declarations for that TLV set
should be added to a file in the same directory by the name
`gen_<field_name>_csv`.
Note that the FIXME included in this commit is difficult to fix, as
we currently pass in the csv files via stdin (so there's no easy
way to ascertain the originating directory of file)
Otherwise we can't really return a variable sized message with more than 65k
results. This was causing an integer overflow in `listchannels` (see #2504 for
details).

@cdecker reports that this gives warnings on exit; and we can't suppress

1. Different times inside the zipfile, since zip seems to save *local* times.
2. A different zipfile order, since zip seems to use filesystem order.
Fix both of these. I don't know if LANG=C is necessary for git

Basically we tell it that every field ending in '_msat' is a struct
amount_msat, and 'satoshis' is an amount_sat. The exceptions are
channel_update's fee_base_msat which is a u32, and
final_incorrect_htlc_amount's incoming_htlc_amt which is also a
'struct amount_msat'.

They're generally used pass-by-copy (unusual for C structs, but
convenient they're basically u64) and all possibly problematic
operations return WARN_UNUSED_RESULT bool to make you handle the
over/underflow cases.
The new #include in json.h means we bolt11.c sees the amount.h definition
of MSAT_PER_BTC, so delete its local version.
