A halfway house between the horror of dynamic generation and the fail of
making everything depend on every header.

I haven't implemented getting transactions from alphad (it needs the values
for the inputs, too), so switch to bitcoind.

I got confused navigating these, especially since Alpha and Bitcoin
have diverged (BIP68 was proposed after Elements Alpha).

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>

This happens for CSV, for example (3-byte encoding), and bitcoind treats
too-long encodings as non-standard.

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).

The libsecp change broke signature checking. Disable it for now,
with a big FIXME. The next version should have a method for S value
checking, and also compact serialization.

switched from pyelliptic to hmac/binascii/cryptography for standard
functions
use our own ECDH implementation to better match the one from secp256k1
finally, add function to create an encrypted onion
Rather than keeping each hop, we can generate it in place since we only
need the first hop result.

This means we can save the partial HMAC of the padding for each step,
rather than the padding itself, when generating it.
Each step now takes the *last*, not *first* part of the onion array.

Doesn't support getblockheader, also some occasional weirdness
with sequence enforcement for mempool? Occasionally I could get
my spend tx into the mempool (doesn't happen with bitcoin).
