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).

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).

Reveals a number of places where we don't handle errors correctly.
Note: this takes about 14.5 GB to test on my x86-64 box.

Not much help yet, but vital when we increase the number of fail points.
Before:
Maximum resident set size (kbytes): 1080148

Major (requiring I/O) page faults: 0
Minor (reclaiming a frame) page faults: 271614
Voluntary context switches: 1
Involuntary context switches: 1083
After:

Rather than generating it after as we return failure. This makes
it easier to save it for the next patch where we want to report failure.
Also put num_peer_outputs in there, so we don't have to access
after->peer on reporting.
