b02176c86b Fix various spec bugs, can now open channels with real nodes! 
* commitment transaction number, as used in locktime/sequence
   fields is actually different from commitment transaction number,
   as used for revocation state. This is confusing and never stated
   in the spec, so we have to do the conversion.
 * max_htlc_value_in_flight is never constrained in the spec, but
   we were requiring it be <= channel size. Instead just clamp the
   values the peer sends us when storing.
 * channel_id calculation was incorrect, we now do some crazy
   conversion hops, which we shouldn't, but will need to change our
   types to fix.
 * Our channel_reserve_satoshis value was too low, just change the
   constant and leave the TODO to figure out what it really should
   be for now.

c47525cb84 Move open_channel message handling into an event 
This simplifies client usage cause peer_handler doesn't have an
interface to shove arbitrary messages in.

6707db6eae Add MAX_FUNDING_SATOSHIS constant. 
This constants defines the maximum value of `open_channel.funding_satoshis`,
currently it's defined to be 2^24 according to the BOLT #2 specification.
Also a test was added to check that the constant is never over 2,1x10^15
(maximum satoshis in bitcoin) if modified.

844097ec01 Greatly simplify channelmonitor pruning tests, and use real funcs 
Instead of hooking into internal data structures and modifying
those, call the actual functions Channel will call and then check
that the preimages map is correct.

d0e9137bc5 Add the OutPoint type for the ChannelMonitor's funding_txo field. 
This structure replaces the (Sha256dHash, u16) tuple that was being used
for the funding output.

374ea1f05e Completely rewrite channel HTLC tracking and processing 
It obviously was nonsensical prior, though its now way more
complicated...there's refactoring work to be done here, but it
should at least kinda sorta work now.
