It was going to be used as proxy from discv5 to rendezvous for les nodes.
We are not using it at the moment, and not clear when we will be using it
and if we are going to use it all.
Additionally it has some memory leaks that need to be fixed, so it is better
to remove it for now and restore once/if we will need it again.
MailServer pruning was implemented as a separate command but that required stopping a mail server and executing the command manually. This change builds pruning into MailServer and can be set using MailServerDataRetention in WhisperConfig.
These changes add a support for syncing data between two Mail Servers. It does not give an easy way to start syncing. This will be solved in the next PR.
This change implements connection manager that monitors 3 types of events:
1. update of the selected mail servers
2. disconnect from a mail server
3. errors for requesting mail history
When selected mail servers provided we will try to connect with as many as possible, and later disconnect the surplus. For example if we want to connect with one mail server and 3 were selected, we try to connect with all (3), and later disconnect with 2. It will to establish connection with live mail server faster.
If mail server disconnects we will choose any other mail server from the list of selected. Unless we have only one mail server. In such case we don't have any other choice and we will leave things as is.
If request for history was expired we will disconnect such peer and try to find another one. We will follow same rules as described above.
We will have two components that will rely on this logic:
1. requesting history
If target peer is provided we will use that peer, otherwise we will request history from any selected mail server that is connected at the time of request.
2. confirmation from selected mail server
Confirmation from any selected mail server will bee used to send a feedback that envelope was sent.
I will add several extensions, but probably in separate PRs:
1. prioritize connection with mail server that was used before reboot
2. disconnect from mail servers if history request wasn't expired but failed.
3. wait some time in RequestsMessage RPC to establish connection with any mail server
Currently this feature is hidden, as certain changes will be necessary in status-react.

This change makes invalidation mechanism more aggressive. With a primary goal to invalidate short living nodes faster. In current setup any node that became known in terms of discovery will stay in this state until it will fail to respond to 5 queries. Removing them earlier from a table allows to reduce latency for finding required nodes.
The second change, one adds a version for discovery, separates status dht from ethereum dht.
After we rolled out discovery it became obvious that our boot nodes became spammed with irrelevant nodes. And this made discovery process very long, for example with separate dht discovery takes ~2s, with mutual dht - it can take 1m-10m and there is still no guarantee to find a max amount of peers, cause status nodes is a very small part of whole ethereum infra.
In my understanding, we don't need to be a part of ethereum dht, and lower latency is way more important for us.

* Make it possible to explicitly disable discovery
Discovery will be disabled in following cases:
- if there are not bootnodes - v5 server will be disabled
because there is no point in running it
- if user defined in config NoDiscovery=true this value will be preserved
even if we have bootnodes
So, basically discovery will be always enabled by default on mobile, unless
it is explicitly specified otherwise.
When statusd is used current behavior is that discovery is disabled by default.
I kept it in this change, but it would be better to change it.
* Fix leftovers
* Add wait group to peer pool to protect from races with p2p.Server
* Change fields only when all goroutines finished
* Turn off discovery after topic searches are stopped
* Don't set period to nil to avoid race with SearchTopic
* Close period chan only when all writers are finished
* add `-status` flag to enable the Status service
* remove status from default APIModules and add it only from statusd if specified
* remove AddAPIModule method
* allow -status flag values to be http or ipc
* add LogEnabled attribute to NodeConfig, used in the call from status-react
* fix use of OverrideRootLogin in tests
* enable logger in tests based on LogLevel
* move LogEnabled before LogFile
This change will greatly simplify writing unit tests when a node is required but data persistence is irrelevant.
I also Introduced some refactoring and unit tests for `StatusNode`.

Summary:
Filter out gas linter error checks for fmt.Fprintf commands. This required defining a custom linter around gas that additionally included the offending code.
Notes:
Gas format, without piping it through gometalinter, gives output like this:
$ gas -fmt=csv geth/jail/console/console.go
geth/jail/console/console.go,21,Errors unhandled.,LOW,HIGH,"fmt.Fprintf(w, ""%s: %s"", consoleEventName, formatForConsole(fn.ArgumentList))"
Gometalinter, by default, does not grab the line of code when it filters gas errors. To resolve this, I created a wrapper around gas (I wasn't sure what to call this "gas wrapper", I opted for gasv2, open to other names).
The first part of the regular expression was taken directly from gometalinter (see https://github.com/alecthomas/gometalinter/blob/master/linters.go#L236), and I then appended ,\".*\" to additionally grab the line of code of the offending line. Lastly, I excluded ".*Errors unhandled.*fmt.Fprintf.*" to filter out only fmt.Fprintf errors around omitted errors.
Also as a result of this change, gas lint output will now include the offending code.
Closes#590
The main goal of this change is to remove async operations from node manager.
Additionally all of the signals from node manager are moved to status backend.
All of the async operation now will have the following behaviour:
- If node in the correct state exit immediatly without error
- If node not in the correct state exit immediatly with error
- In all other cases spawn a goroutine with wanted operation
- All the progress regarding that operation will be reported
by using signals
- Signals should be handled in once place, which is StatusBackend
There are 2 potentially breaking changes:
- Empty event field will be ommited when Envelope is sent to a client
- All errors will be delivered to a client as an Envelope, previously
some errors (NodeExists, NoRunningNode) were delivered synchronously
