e54c0adced gossip: Do not consider half-open connections for routes 
Connections are in a half-open state after receiving the
`channel_announcement` and before the `channel_update` makes them
usable, so we need to ignore channels that are not yet fully open.

fca9bf1a16 gossip: Partially sign channel_announcements 
We can already add our own signatures, will have to defer remote
signatures until we implement the channel setup messages from the spec.

57d5ae96a4 routing: Added channel_id and directions to connections 
The gossip protocol spec refers to channels by their `channel_id` and
a direction. Furthermore, inbetween the `channel_announcement` and the
`channel_update` for either direction, the channel direction is in an
undefined state and cannot be used, so added the `half_add_connection`
function and an `active` flag to differentiate usable connections from
unusable ones.

1c4d4f8c91 proto: Added nested_pkt 
This is mainly used to transport the new, standardized protocol, over
the old legacy transport. Allows us to replace the serialization and
transport gradually instead of all at once.

ca9fb0376a wire: Removing global secpctx 
Changed the generation of messages so that we pass in a reference to the
secp256k1_context if it is required by the underlying primitive
function. This gets rid of the global `secp256k1_ctx` variable and
adheres closer to how we've been handing in the context so far.

sphinx: Fixed a buffer overflow in hmac generation 
Our HMACs are truncated to 20 byte, but sodium still generates 32 byte
HMACs and we were handing in a buffer that was too small, so we
overflowing the buffer by 12 bytes. This manifested itself only in the
32 bit variant because of different alignment in the 64bit version.

Fixes #94.
