Eclair wasn't stopping anymore when two instances were started with the
same ports.
Note: we should probably go one step further and put a lock in the datadir
directory. For now we just check if the main TCP port is in use and fail fast.
Most notably, we do not anymore discard previously signed updates.
Instead, we re-send them and re-send the exact same signature. For that to
work, we had to be careful to re-send rev/sig in the same order, because
that impacts whatever is signed.
NB: this breaks storage serialization backward compatibility
* reworked payment lifecycle
* fixed retry logic (infinite loop in some cases)
* check update signature
* keep track of the list of errors and routes tried
* added support for sending bolt11 payment request in the API
* updated eclair-cli and deleted deprecated TESTING.md (closes#112)
* removed useless application.conf in eclair-node
* now handling CMD_CLOSE in shutdown/negotiating/closing states
* added no-op handlers for FundingLocked and CurrentFeeRate messages
* cleaning up stale announcements on restart
* more informative/less spam logs in Channel
* (gui) Wrapping payment events to display date of event
* Also added controls to item content in cell factory overrides. This
should prevent prevent duplicates as reported in #115
* handle overflow for field 'max-htlc-value-in-flight'
* moved serialization of uint64 to codecs class
* moved constraint check
* fix configuration (was using hard coded values)
* using UInt64.MaxValue in test constants
* added a default handler for 'ok' messages in Channel
* update_add_htlc wire message: swap expiry and payment hash fields
see BOLT 2
* fix accept_channel wire encoding
'min depth' and 'hlc min msat' fields we swapped
* gui: set ip to "unknown" when it has not been set in node announcements
* reduced logging for Reconnect events
* peer is now able to switch transports, in case of undetected disconnection
* now using an exponential backoff retry when reconnecting to peers
* put the arguments of the 'open' http method in the same order as the uri
