Add support for bumping the fees of a dual funding transaction.
We spawn a transient dedicated actor: if the RBF attempt fails, or if we
are disconnected before completing the protocol, we should forget it.
Add more tests for scenarios where an unconfirmed channel is force-closed,
where the funding transaction that confirms may not be the last one.
* Add a "stop" API method
This API call was added for certain uses cases where killing the process was impractical but internally it just calls `sys.exit()`.
Eclair is designed to shutdown cleanly when its process is killed and this is still the recommended way of stopping it.
The `channelbalances` API call retrieves information about the balances of all local channels, not just those with usable outgoing balances that are enabled for sending.
This change also adds the `isEnabled` attribute to the json results for both the new `channelbalances` and old `usablebalances` API calls.
We introduced a task to regularly compute network statistics (mostly about
channel parameters such as expiry and fees).
The goal was to use this information in the MPP split algorithm to decide
whether to split a payment or not.
But we haven't used it, and I'm not sure anymore that it's useful at all.
If node operators are interested in network statistics, an ad-hoc
on-the-fly computation would make more sense.
Refactor the API handlers.
Split handlers and directives in several files to make them more composable.

* Type all amounts used in eclair
* Add eclair.MilliSatoshi class
* Use bitcoin-lib 0.14
* Add specialized codecs for Satoshi/MilliSatoshi
* Rename 'toSatoshi' to 'truncateToSatoshi' to highlight it's a precision-losing conversion
There is no unique identifier for payments in LN protocol. Critically,
we can't use `payment_hash` as a unique id because there is no way to
ensure unicity at the protocol level.
Also, the general case for a "payment" is to be associated to multiple
`update_add_htlc`s, because of automated retries. We also routinely
retry payments, which means that the same `payment_hash` will be
conceptually linked to a list of lists of `update_add_htlc`s.
In order to address this, we introduce a payment id, which uniquely
identifies a payment, as in a set of sequential `update_add_htlc`
managed by a single `PaymentLifecycle` that ends with a `PaymentSent` or
`PaymentFailed` outcome.
We can then query the api using either `payment_id` or `payment_hash`.
The former will return a single payment status, the latter will return a
set of payment statuses, each identified by their `payment_id`.

Port the existing API functionalities over a new structure of HTTP endpoints, with the biggest difference being the usage of **named parameters** for the requests (responses are unchanged). RPC methods have become endpoints and the parameters for each are now passed via form-params (clients must use the header "Content-Type" : "multipart/form-data"), this allows for a clearer interpretation of the parameters and results in more elegant parsing code on the server side. It is possible to still use the old API version via a configuration key.
Old API can be used by setting `eclair.api.use-old-api=true`.
This fixes#695, and also adds the channel point in the default channel output.

* ignore answers to CMD_UPDATE_FEE

* improvements in eclair-cli:
- Made default `channel`/`channels` outputs more useful.
- Added support for timestamp filtering to `audit` and `networkfees`.
* added `ChannelPersisted` event
Added a new `AuditDb` which keeps tracks of:
- every single payment (received/sent/relayed)
- every single network fee paid to the miners (funding, closing, and all commit/htlc transactions)
Note that network fees are considered paid when the corresponding tx has reached `min_depth`, it makes sense and allows us to compute the fee in one single place in the `CLOSING` handler. There is an exception for the funding tx, for which we consider the fee paid when the tx has successfully been published to the network. It simplifies the implementation and the tradeoff seems acceptable.
Three new functions have been added to the json-rpc api:
- `audit`: returns all individual payments, with optional filtering on timestamp.
- `networkfees`: returns every single fee paid to the miners, by type (`funding`, `mutual`, `revoked-commit`, etc.) and by channel, with optional filtering on timestamp.
- `channelstats`: maybe the most useful method; it returns a number of information per channel, including the `relayFee` (earned) and the `networkFee` (paid).
The `channels` method now returns details information about channels. It makes it far easier to compute aggregate information about channels using the command line.
Also added a new `ChannelFailed` event that allows e.g. the mobile app to know why a channel got closed.
* reworked eclair-cli
* API is disabled by default, disabled CORS and require basic auth password
* better error handling
* Fixed latest version in README
* Increased connection timeout to 15s in electrum client test
* Rgb in NodeAnnouncement is now a Color object
Makes the color field more practical to handle and enable finer
serialization with a more readable code.
allnodes command in api now exports a list with node announcements.
* Added api call to list all the channels updates
This call can also filter the channels for a given nodeId
This fixes#344.
* reworked peer management
- connection and channel opening are now separated, simplified
`switchboard`
- use a single authenticator for both incoming and outgoing connections
- `peers` api call now returns current state and channel count
* fixed last commit
* fixed last merge
* added inetsocketaddress serializer
Service pattern matching code visually separates each method and
params to improve the code readability and maintenance. Route completion
is handle on a case by case basis, for each call. This enables better error
management and useful feedback to the caller.
Added custom rejections to handle cases where the given rpc method or
params are not found or not correct.
HTTP code should now be consistent with the error returned.
* 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
