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 4e23f9916d script: encode numbers minimally. 
This happens for CSV, for example (3-byte encoding), and bitcoind treats
too-long encodings as non-standard.

Rusty Russell 2ab9e3bd7f doc/deployable-lightning: corrections and fixes. 
1) Note incorrect label in txs in Fig1 of LN paper.
2) "an atomic-swap an on-chain.." -> "an atomic-swap *to* an on-chain"
3) "By using a dual anchor and escape transactions" -> "By using a rebalanced single anchor"
4) References to appendices fixed.
5) Move escape transaction scripts out to escape appendix.
6) Fix URL in bibliography (missing comma).

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).
