As part of the new Discord <-> Status Community Import functionality, we're adding an API that extracts all discord categories and channels from a previously exported discord export file. These APIs can be used in clients to show the user what categories and channels will be imported later on. There are two APIs: 1. `Messenger.ExtractDiscordCategoriesAndChannels(filesToimport []string) (*MessengerResponse, map[string]*discord.ImportError)` This takes a list of exported discord export (JSON) files (typically one per channel), reads them, and extracts the categories and channels into dedicated data structures (`[]DiscordChannel` and `[]DiscordCategory`) It also returns the oldest message timestamp found in all extracted channels. The API is synchronous and returns the extracted data as a `*MessengerResponse`. This allows to make the API available status-go's RPC interface. The error case is a `map[string]*discord.ImportError` where each key is a file path of a JSON file that we tried to extract data from, and the value a `discord.ImportError` which holds an error message and an error code, allowing for distinguishing between "critical" errors and "non-critical" errors. 2. `Messenger.RequestExtractDiscordCategoriesAndChannels(filesToImport []string)` This is the asynchronous counterpart to `ExtractDiscordCategoriesAndChannels`. The reason this API has been added is because discord servers can have a lot of message and channel data, which causes `ExtractDiscordCategoriesAndChannels` to block the thread for too long, making apps potentially feel like they are stuck. This API runs inside a go routine, eventually calls `ExtractDiscordCategoriesAndChannels`, and then emits a newly introduced `DiscordCategoriesAndChannelsExtractedSignal` that clients can react to. Failure of extraction has to be determined by the `discord.ImportErrors` emitted by the signal. **A note about exported discord history files** We expect users to export their discord histories via the [DiscordChatExporter](https://github.com/Tyrrrz/DiscordChatExporter/wiki/GUI%2C-CLI-and-Formats-explained#exportguild) tool. The tool allows to export the data in different formats, such as JSON, HTML and CSV. We expect users to have their data exported as JSON.

Whisper API Extension
API
shhext_getNewFilterMessages
Accepts the same input as shh_getFilterMessages.
Returns
Returns a list of whisper messages matching the specified filter. Filters out
the messages already confirmed received by shhext_confirmMessagesProcessed
Deduplication is made using the whisper envelope content and topic only, so the same content received in different whisper envelopes will be deduplicated.
shhext_confirmMessagesProcessed
Confirms whisper messages received and processed on the client side. These
messages won't appear anymore when shhext_getNewFilterMessages
is called.
Parameters
Gets a list of whisper envelopes.
shhext_post
Accepts same input as shh_post.
Returns
DATA, 32 Bytes - the envelope hash
shhext_requestMessages
Sends a request for historic messages to a mail server.
Parameters
Object- The message request object:
mailServerPeer:URL- Mail servers' enode addessfrom:QUANTITY- (optional) Lower bound of time range as unix timestamp, default is 24 hours back from nowto:QUANTITY- (optional) Upper bound of time range as unix timestamp, default is nowtopic:DATA, 4 Bytes - Regular whisper topicsymKeyID:DATA- ID of a symmetric key to authenticate to mail server, derived from mail server password
Returns
Boolean - returns true if the request was send, otherwise false.
Signals
Sends sent signal once per envelope.
{
"type": "envelope.sent",
"event": {
"hash": "0xea0b93079ed32588628f1cabbbb5ed9e4d50b7571064c2962c3853972db67790"
}
}
Sends expired signal if envelope dropped from whisper local queue before it was sent to any peer on the network.
{
"type": "envelope.expired",
"event": {
"hash": "0x754f4c12dccb14886f791abfeb77ffb86330d03d5a4ba6f37a8c21281988b69e"
