This broke with COPTFLAGS="-flto -O3", and so I took a look (it
complains more than normal because main isn't there). We should never
be running update-mocks except on programs expected to compile: in
this case, that's tools/test/run-test-wire.c.
Remove the code which tries to run this, which also means
non-developers won't be running update-mocks!

Requiring the caller to allocate them is ugly, and differs from
other types.
This means we need a context arg if we don't have one already.

This works better in general: let printwire_x do the work of figuring
out how to demarshal x. This is particularly important for TLVs, which
require a call to tlv_x_new() first.

We make them return bool, and always use names `cursor` and `plen` in
callers, for simplicity.
Also, `...` means "loop until finished" not "loop this many bytes".

And turn "" includes into full-path (which makes it easier to put
config.h first, and finds some cases check-includes.sh missed
previously).
config.h sets _GNU_SOURCE which really needs to be done before any
'#includes': we mainly got away with it with glibc, but other platforms
like Alpine may have stricter requirements.

Note that check-whitespace and check-bolt already do this, so we
can eliminate redundant lines in common/Makefile and bitcoin/Makefile.
We also include the plugin headers in ALL_C_HEADERS so they get
checked.

This avoids overwriting the ones in git, and generally makes things neater.
We have convenience headers wire/peer_wire.h and wire/onion_wire.h to
avoid most #ifdefs: simply include those.

Because it required update-mocks, which is a hack which relies on the
format of linker errors (!) I'd prefer to make this --enable-developer

We need to tell it that the tmp file is an intermediate, so doesn't need

This simplifies the dependencies:
1. Objs depend on headers, not other objs.
2. Programs depend on objs.
3. A .o file will generally implicitly depend on the .c file it's built from.
4. If a file has a build line, it's often better to list all deps there.
5. I spotted some missing 'make clean' files.
The particular problem in this case seems to be that make would use
tools/test/gen_test.c before it was ready. It's probably confused by
the use of recursive make via update-mocks, so explicitly split that
into two stages.

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

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.
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.
