Naturally, it's a struct pubkey. However, those are large, and take
time to marshal, so gossipd treats them as node_id which is a simple
array. It adds explicit checks at the right points to make sure
they're valid pubkeys.
However, the next commit adds TLV test vectors, which assumes we treat
node_id as a point (thus catch invalid values when parsing). The best
solution is to restrain our types here to exactly those we've
optimized for.

This makes it build for me on FreeBSD 11:
1. $(MAKE) has to passed through into update-mocks.
2. FreeBSD sed doesn't turn \n into a newline on RHS.
3. Bash and mako dependencies were missing from INSTALL.md
Fixes: #2850

TLVs have an implicit `len` field, so allow expressions containing
that (eg. `len-1`), but assume it means "the remainder of the
message".
This means in most places, f.size() needs an fallback for the
implicit-length case.

They're currently called varint, but there's a proposal to call them all
bigsize. Allow both for now.

originally done so that any field within a subtype needed context,
that would be reflected at the top-most layer. in reality, we
allocate subtype fields off of the instance of the subtype, so
there's no need to check beneath the 'top' layer of field/types
in a message to determine whether or not to pass in a context.
Add parsing know-how for enum fields. This is necessary for
internally defined wire generators. Enums are denoted by prefixing
the field with an `e:`.
Ex:
msgdata,msg_name,field_name,e:enum_type,
we rely, perhaps a bit hackily, on there only being one copy of
each type object floating about. using `deepcopy` on a Message
for message extensions destroys this paradigm, which breaks
things in the case where it's a later defined subtype that contains
variable-length members.
to fix this, we modify `__deepcopy__` on the Field class, such
that it preserves the reference to the original type_obj instance.
remove extra space from the lead-in for inline comments
so that a provided comment like this
# This is a comment
will appear like this
/* This is a comment */
Add a test for checking that the bolt-gens do the right thing
for a fairly exhaustive test case set (and that it compiles).
Note that this doesn't check that we've got the memory assignment
pieces worked out.
It's got a kind of exotic reliance on the update-mocks in that in
order to depend on as little of the wire/ code as possible (we
only import wire/wire.h), we include an AUTOGENERATE comment
in the test_cases CSV file, and then run update-mocks as part of
the build for that file.
we'll need this for internal wire message formats. also disambiguates
from 'bolt message optional fields', which we rename to extensions here.
example of an optional field declaration (note the ? prefixing the
type):
msgdata,msg_name,field_name,?type,count
these are handled with either a boolean if they're not present,
or a true value and then the object if they are.
if there are any comments that aren't "attached" to a message,
print them at the top of the generated file. we need this for
the fancy auto-gen'd dependencies in the tool-wiregen tests.
The new TLV spec uses BigSize, like Bitcoin's CompactInt but
*little-endian*. So change our name for clarity, and insist that
decoding be minimal as the spec requires.

the RFC's extract-format.py is switching to a new format.
this script can correctly parse them.
mostly moves logic over from generate-wire.py, uses a
Python formatting libarary called mako, which needs to be
installed prior to running this script.
you can add it to your system with
sudo apt-get install python3-mako

Save some overhead, plus gets us ready for giving subdaemons direct
store access. This is the first time we *upgrade* the gossip_store,
rather than just discarding.
The downside is that we need to add an extra message after each
channel_announcement, containing the channel capacity.
