Use `LC_ALL=C sort` instead of `sort` so that mocks get sorted in
the same way on all developers' environments.
Re-record the result of `make update-mocks`.

We currently abuse the added_htlc and failed_htlc messages to tell channeld
about existing htlcs when it restarts. It's clearer to have an explicit
'existing_htlc' type which contains all the information for this case.

Before this patch we used to send `double`s over the wire by just
copying them. This is not portable because the internal represenation
of a `double` is implementation specific.
Instead of this, multiply any floating-point numbers that come from
the outside (e.g. JSONs) by 1 million and round them to integers when
handling them.
* Introduce a new param_millionths() that expects a floating-point
number and returns it multipled by 1000000 as an integer.
* Replace param_double() and param_percent() with param_millionths()
* Previously the riskfactor would be allowed to be negative, which must
have been unintentional. This patch changes that to require a
non-negative number.
Changelog-None
Before this patch we used `int` for error codes. The problem with
`int` is that we try to pass it to/from wire and the size of `int` is
not defined by the standard. So a sender with 4-byte `int` would write
4 bytes to the wire and a receiver with 2-byte `int` (for example) would
read just 2 bytes from the wire.
To resolve this:
* Introduce an error code type with a known size:
`typedef s32 errcode_t`.
* Change all error code macros to constants of type `errcode_t`.
Constants also play better with gdb - it would visualize the name of
the constant instead of the numeric value.
* Change all functions that take error codes to take the new type
`errcode_t` instead of `int`.
* Introduce towire / fromwire functions to send / receive the newly added
type `errcode_t` and use it instead of `towire_int()`.
In addition:
* Remove the now unneeded `towire_int()`.
* Replace a hardcoded error code `-2` with a new constant
`INVOICE_EXPIRED_DURING_WAIT` (903).
Changelog-Changed: The waitinvoice command would now return error code 903 to designate that the invoice expired during wait, instead of the previous -2
We cannot let users use `sendcustommsg` to inject messages that are handled
internally since it could result in our internal state tracking being borked.
I really want a type which means "I am a wrapped onion reply" as separate
from "I am a normal wire msg". Currently both user u8 *, and I got very
confused trying to figure out where each one was an unwrapped error msg,
or where it still needed (un)wrapping.

Add towire_int() and fromwire_int() functions to "(de)serialize"
"int". This will only work as long as both the caller of towire_int()
and the caller of fromwire_int() use the same in-memory representation
of signed integers and have the same sizeof(int).

TIL: `rename` doesn't like its source and target to be on different
partitions. This was causing the `hsmtool` tests to fail whenever we ran them
on a different partition than the lightning-dir (e.g., `/dev/shm` for faster
testing), because we made the backup copy in the current working directory.
This changes this and creates the backup next to the original file, which has
a reasonable chance to be on the same partition.
Changelog-Changed: hsmtool: The `hsmtool` now creates its backup copy in the same directory as the original `hsm_secret` file.
Recent FreeBSD versions use LLVM's lld as a linker, not the GNU ld.
Their behavior slightly differs, so adapt the build system to handle
either one.
* The LLVM's linker prints "undefined symbol:" instead of
"undefined reference to". Tweak tools/mockup.sh to also look for that
message.
* The LLVM's linker may only print the first dozen errors (omitting
the rest to avoid flooding the screen). tools/update-mocks.sh relies
on getting all errors as it extracts the missing symbols' names from
the error output and creates mocks for them. Detect if errors were
omitted and re-run, telling the linker to not omit any. The GNU linker
does not support -error-limit=0, so unfortunately we can't just run
with that option unconditionally from the first attempt.
* Nit: FreeBSD's sed(1) prints "t" for "\t" instead of a horizontal tab.
Use a verbatim tab in the command, instead of "\t" which works on
both.
Changelog-Fixed: Developer mode compilation on FreeBSD.

This, in the case of data loss on a channel with `option_static_remotekey`
negotiated, allows to likely (if the dbid is not unreasonable) recover
the funds from a remote unilateral close just with the hsm_secret.
Changelog-added: A new command, 'guesstoremote', is added to the hsmtool. It is meant to be used to recover funds after an unilateral close of a channel with `option_static_remotekey` enabled.
Since the parser itself just parses and doesn't include validation anymore we
need to put that functionality somewhere. The validation consists of enforcing
that the types are in monotonically increasing order without duplicates and
that for the even types we know how to handle it.
We were weaving in and out of generic code through `fromwire_tlvs` with custom
parameters defining the types in that namespace. This hard-wires the parser
with the namespace's types. Slowly trying to deprecate `fromwire_tlvs` in
favor of this typesafe variant.
This takes a dbid, a "depth" (how many points to dump), the hsm_secret
path, and a potential password to dump informations about all
commitments until the depth.

Our TLV serializer relies on TLV outputs to be ordered by type
number. Prior to this commit we relied on 1) the ordering in the
RFC to be correct and 2) users to be using a version of Python that
respects stable ordering of dicts (i.e. Python 3.7+)
Instead of relying on these implicitly, we now explicitly sort messages
by type number when the TLV sets.
Resolves#2956.

1. These days we delete the [Unreleased] tag during rcs.
2. Make sure we test the release build process during rc1, since I
screwed that up last release.
3. Add a section on rc2, etc.
4. Do final release via a github PR, since I screwed that up on the
prior release.
5. Update `tools/build-release.sh` and instructions to show that we now
make a reproducible build for Ubuntu 18.04 x86-64.
