WebSocket is a bit weird:
1. It starts like an HTTP connection, but they send special headers.
2. We reply with special headers, one of which involves SHA1 of one of theirs.
3. We are then in WebSocket mode, where each frame starts with a 2-20 byte
header.
We relay data in a simplistic way: if either side sends something, we
read it and relay it synchronously. That avoids any gratuitous
buffering.

This adds a new configuration, --enable-fuzzing (which is more than
welcome to be coupled with --enable-address-sanitizer), to pass the
fuzzer sanitizer argument when compiling objects. This allows libfuzzer
to actually be able "to fuzz" by detecting coverage and be smart when
mutating inputs.
As libfuzzer brings its own ~~fees~~ main(), we compile objects with
fsanitize=fuzzer-no-link, and special-case the linkage of the fuzz
targets.
A "lib" is added to abstract out the interface to the fuzzing tool used.
This allow us to use the same targets to fuzz using AFL, hongfuzz or w/e
by adding their entrypoints into libfuzz. (h/t to practicalswift who

Changelog-Changed: build: default compile output is prettier and much less verbose
We had them split according the separate use-cases:
- testing
- doc-gen
- wire-gen
But that was causing new contributors to miss some dependencies when they
first got hacking. So this consolidates all of our own dependencies in a root
requirements.txt, with the notable exception of `pyln-client`, `pyln-testing`
and `pyln-proto` which are distributed as PyPI modules and therefore have
their own dependencies that need to be tracked in the module root.

Most is taken from lightningd/bitcoind and adapted. This currently
exposes 5 commands:
- `getchaininfo`, currently called at startup to check the network and
whether we are on IBD.
- `getrawblockbyheight`, which basically does the `getblockhash` +
`getblock` trick.
- `getfeerate`
- `sendrawtransaction`
- `getutxout`, used to gather infos about an output and currently used by
`getfilteredblock` in `lightningd/bitcoind`.
On CI it is nice to cache the external dependencies. However if we
always compile them in the same folder we cannot cache for multiple
different architectures. After this commit native compile targets will
still live in `external` but cross compiled versions will live in
`external/<arch>`.
Put `LC_ALL=C sort` in a variable and use it everywhere. It was
forgotten in one place.
Without `LC_ALL=C` it would order `a.b` before `a-c` even though
`. (0x2E)` > `- (0x2D)`.
Changelog-None
Before this change `make` would build everything but the docs.
They would be built during `make install` which is unexpected.
Add a dependency to `doc-all` to the `default` target so that docs are
build together with the rest of the programs. Leave the `install-data`
as is, to still build the docs if they are not built yet during install.
Changelog-None
This should not affect any consumer of the API since we just shift the actual
implementation from one side to the other, and keep aliases in place so
scripts don't break.
We also bump the version number from 0.0.7.3 to 0.7.4 which allows us to be in
sync with c-lightning itself, and remove the superfluous `0` in front.

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.

Dumb programs which have a --daemon option call fork() early. This is
terrible UX since startup errors get lost: the program exits with
"success" immediately then you discover via the logs that it didn't
start at all.
However, forking late introduced a heap of problems with changing
pids. Instead, fork early but keep stderr and the parent around: if
we fail early on, the parent fails with us. We release our parent
with an explicit action just before the main loop.

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.
updates the bolt version to 6639cef095a2ecc7b8f0c48c6e7f2f906fbfbc58.
this requires us to use the new bolt parser at generate-bolt.py
and updates to all of the type specifications (ie. from u8 -> byte)
These are generalized from our internal implementations.
The main difference is that 'struct json_escaped' is now 'struct
json_escape', so we replace that immediately.
The difference between lightningd's json-writing ringbuffer and the
more generic ccan/json_out is that the latter has a better API and
handles escaping transparently if something slips through (though
it does offer direct accessors so you can mess things up yourself!).

In particular, `make unittest/bitcoin/test/run-secret_eq_consttime`
didn't set VALGRIND if it was set via config.vars, so runs for a *long*
time.

These weren't checked by CI yet, and they are really short so I just added
them to the check-python target.

We need to do it in various places, but we shouldn't do it lightly:
the primitives are there to help us get overflow handling correct.

This is based on Christian's change, but removes all trace of the old codes.
I've proposed another spec change which removes this code altogether:

git is needed to generate version information
Add a sanity check so that the build don't continue with an empty VERSION. This
is useful for sandboxed build where we might have forgot to include git.

There were a few reports that upgrading Ubuntu recently caused issues
because we assert that the sqlite3 library version matches the one we
were built with. 'make' doesn't fix this, because it doesn't know the
external libraries have changed.
Fix this harder, with a helper which updates a file every binary depends
on, which gets relinked every time so we detect link changes.

Note that this changes the order of arguments to pipecmd to match the
documentation, so we fix all the callers!
Also make configure re-run when configurator changes.

This will kill a test that was running for 550 seconds, so that we
get a traceback before the travis inactivity timeout of 600 seconds
kicks in. The traceback should show us which test got stuck and where
it got stuck.

The only change is that the final_incorrect_htlc_amount field is now 64
bit. Since no implementation yet parses that field, we just updated it
quietly in the spec.

After Ubuntu 18.10 upgrade, lots of new flake8 warnings.
$ flake8 --version:
3.5.0 (mccabe: 0.6.1, pycodestyle: 2.4.0, pyflakes: 1.6.0) CPython 3.6.7rc1 on Linux
Note it seems that W503 warned about line breaks before binary
operators, and W504 complains about them after. I prefer W504, so
disable W503.

This was from a different series, so I just cherry-picked it.
It adds ccan/membuf as a depenency of ccan/rbuf, though we don't use
it directly yet.

If another channel has set the optional `htlc_maximum_msat` field,
we should correctly parse that field and respect it when drawing up
routes for payments.
The code to regenerate the local BOLT copy was causing eternal rebuild.
So only build if it's wrong.

BOLT 7's been updated to split the flags field in `channel_update`
into two: `channel_flags` and `message_flags`. This changeset does the
minimal necessary to get to building with the new flags.
