And nail "make check-source" to that specific version (which is a commit id,
not a branch name, so needs a different syntax for git).

To avoid everything pulling in HTLCs stuff to the opening daemon, we
split the channel and commit_tx routines into initial_channel and
initial_commit_tx (no HTLC support) and move full HTLC supporting versions
into channeld.

In particular, it reassured me that the ammag obfuscation step occurs
even for the initial failmsg creator.

We alternated between using a sha256 and using a privkey, but there are
numerous places where we have a random 32 bytes which are neither.
This fixes many of them (plus, struct privkey is now defined in terms of
struct secret).

This just means we put the outgoing_cltv_value where we used to put zeroes.
The old daemon simply ignores this, but the new one should check it as per
BOLT 4.

So far this was simply set to a zero-length end-to-end payload. We
don't have any plans of re-adding it for the moment, so let's get rid
of the unused code.
The spec says that we use the libsecp256k1 style ECDH, which uses the
full compressed pubkey from the scalar multiplication which is then
hashed. This is in contrast to the btcsuite implementation which was
only using the hashed X-coordinate.
Our HMACs are truncated to 20 byte, but sodium still generates 32 byte
HMACs and we were handing in a buffer that was too small, so we
overflowing the buffer by 12 bytes. This manifested itself only in the
32 bit variant because of different alignment in the 64bit version.
Fixes#94.

Generally, the pattern is: everything returned is allocated off the return
value, which is the only thing allocated off the context. And it's always
freed.
Also, tal_free() returns NULL, so it's useful for one-line error
cleanups.
