7f53a3e46e BOLT 8: make it clear that there are *two* chaining keys. 
lnmessage got this wrong!  It would pass our test vectors, but actually fail
in real usage, since it used the same `ck`.

Also, nonce rotation happens after 1000 encryptions, which is when the nonce
reaches 1000 (since it's zero based!), not when it *exceeds* 1000.

Remove reference to DER encoding for public keys in compressed format (#742) 
ECDSA signatures in Bitcoin are DER-encoded but public keys are not.

The compressed format for public keys is for example standardized in

7cb708da20 BOLT08: define e and s within the context of the noise handshake 
When the notation of the noise protocol framework is being introduced the terms `ck` and `k` are being explained but `e` and `s` are only referred to was public keys. I fixed that by stating what they stand for and noting that `s` is usually the the `nodeid` in the context of the Lightning Network protocol.

BOLT 8: specify that chacha nonces are 96-bit little-endian 
This commit fixes an oversight within the spec that details the
encryption nonces as being encoded in a big-endian form rather an a
little-endian for as is intended.

Since our internal nonces are 64-bit in order to match with the Noise
spec, we encoded the 96-bit nonce as 32-bits of leading zeroes followed
by the 64-bit little-endian value.
