Rusty Russell 3374ddd2a6 bitcoin: use a length arg to bitcoin_tx_from_hex
Our json parser doesn't use nul-terminated strings.

Rusty Russell 7cf786f1f4 pull_bitcoin_tx: allocate outputs off tx itself.
All the members of the transaction should be allocated off the
transaction, as they have the same lifetime.

Rusty Russell 4b02c6f558 locktime: nice abstractions for absolute and relative locktimes.
I got confused navigating these, especially since Alpha and Bitcoin
have diverged (BIP68 was proposed after Elements Alpha).

Rusty Russell 4c42930940 bitcoin/tx, protobuf_convert: support BIP68 as implemented.
The format for both the nSequence field and the stack arg for
OP_CHECKSEQUENCEVERIFY is either:

  Time-relative:	[Bit 22 = 1] 00000 <time-shifted-by-9>
  Block-relative:	[Bit 22 = 0] 00000 <number of blocks>

Rusty Russell 454a3867e5 BIP68 support (nSequence enforcement)
The latest version of the BIP doesn't use inversion, but does use
bitshifts.

It also uncovered a bug in the test scripts: the block timestamps
creep forward when we generate large numbers of blocks (UpdateTime
insists it be > GetMedianTimePast() so it's valid).  We need to take
this into account when waiting for the median to move (reduced it from
60 to 30 seconds, since that adds about 14 seconds).

It's trivial to add later as an optional field.

Rusty Russell 66b1df4036 tx: locktime should be 0.
It doesn't matter until we start setting sequence numbers properly,
so hasn't been noticed until now.

Rusty Russell 602117e8bb Add valgrind memcheck helpers.
Otherwise valgrind tells you when you test a hash; you want to
know if you hash uninitialized memory long before that.

Put ccan first, openssl next, then standard headers, then locals.

It's not very interesting if you're looking for LN code.
