Fixes#9433 : this was due to the fact that `.-response-to` was
returning nil, because of the dash in the name, instead in this cases
`(aget .. "response-to")` should be used.
Fixes#9431 : This was a left-over from the move from message-groups to
message-list, and the code was not updated.
Fixes#9430#9429 Both of these were due to the same issue, cofx were
wrongly passed to the function resulting in the db being updated but the
fxs being discarded.
There's still a separate issue that might result in messages not being
saved on logout, because of a race condition (if you logout while is
fetching messages, some of the message might not be saved). I will
address that separately as we might be able to just save messages as
they come in status-go, rather then having to pass them to status-react
and back to status-go for saving.

This commit enables parsing of messages in status-go.
Currently only a few messages are supported in status-protocol-go.
For now we only enable Message types.
Status-react will conditionally use the parsed version if present.
Eventually this can be moved to a separate signal/different structure,
but for the time being is best to validate with the minimum amount of
changes.
The next step would be handle validation and processing of the field in
status-go, so we can skip saving the message from status-react.
This commit should improve performance of receiving messages from a
chat, although haven't had time to validate that.

This commit does a few things:
==== Ordering of messages ====
Change the ordering of messages from a mixture of timestamp/clock-value to use
only clock-value.
Datemarks are now not used for sorting anymore, which means that the
order of messages is always causally related (not the case before, as we
were breaking this property by sorting by datemark), but datemark
calculation is unreliable (a reply to a message might have a timestamp <
then the message that is replied to).
So for timestamp calculation we
naively group them ignoring "out-of-order timestamp" messages, although
there's much to improve.
It fixes an issue whereby the user would change their time and the
message will be displayed in the past, although it is still possible to
craft a message with a lower clock value and order it in the past
(there's no way we can prevent this to some extent, but there are ways
to mitigate, but outside the scope of this PR).
==== Performance of receiving messages ====
The app would freeze on pulling messages from a mailserver (100 or so).
This is due to the JS Thread being hogged by CPU calculation, coupled
with the fact that we always tried to process messages all in one go.
This strategy can't scale, and given x is big enough (200,300,1000) the
UI will freeze.
Instead, each message is now processed separately, and we leave a gap
between processing each message for the UI to respond to user input
(otherwise the app freezes again).
Pulling messages will be longer overall, but the app will be usuable
while this happen (albeit it might slow down).
Other strategies are possible (calculate off-db and do a big swap,
avoiding many re-renders etc), but this is the reccommended strategy by
re-frame author (Solving the CPU Hog problem), so sounds like a safe
base point.
The underlying data structure for holding messages was also changed, we
used an immutable Red and Black Tree, same as a sorted map for clojure, but we use
a js library as is twice as performing then clojure sorted map.
We also don't sort messages again each time we receive them O(nlogn), but we
insert them in order O(logn).
Other data structures considered but discarded:
1) Plain vector, but performance prepending/insertion in the middle
(both O(n)) were not great, as not really suited for these operations.
2) Linked list, appealing as append/prepend is O(1), while insertion is
O(n). This is probably acceptable as messages tend to come in order
(from the db, so adding N messages is O(n)), or the network (most of
them prepends, or close to the head), while mailserver would not follow this path.
An implementation of a linked list was built, which performed roughtly the
same as a clojure sorted-map (although faster append/prepend), but not
worth the complexity of having our own implementation.
3) Clojure sorted-map, probably the most versatile, performance were
acceptable, but nowhere near the javascript implementation we decided on
4) Priority map, much slower than a sorted map (twice as slow)
5) Mutable sorted map, js implementation, (bintrees), not explored this very much, but from
just a quick benchmark, performance were much worse that clojure
immutable sorted map
Given that each message is now processed separately, saving the chat /
messages is also debounced to avoid spamming status-go with network
requests. This is a temporary measure for now until that's done directly
in status-go, without having to ping-pong with status-react.
Next steps performance wise is to move stuff to status-go, parsing of
transit, validation, which is heavy, at which point we can re-consider
performance and how to handle messages.
Fixes also an issue with the last message in the chat, we were using the
last message in the chat list, which might not necessarely be the last
message the chat has seen, in case messages were not loaded and a more
recent message is the database (say you fetch historical messages for
1-to-1 A, you don't have any messages in 1-to-1 chat B loaded, you receive an
historical message for chat B, it sets it as last message).
Also use clj beans instead of js->clj for type conversion

All the code has been implemented in statusgo: status-im/status-go#1466
Basically all the whisper filter management is done at that level.
Technical description
On startup we load all chats and send a list of them to status go:
For a public chat: {:chatId "status"}, we create a single filter, based on the name of the chat.
For each contact added by us, each user in a group chat and each one to one chat open, we send:
{:chatId "0x", :oneToOne true}. This will create a chats, to listen to their contact code.
Any previously negotiated topic is also returned.
Once loaded, we create our filters, and upsert the mailserver topics, both of which are solely based on the filters loaded.
In order to remove a chat, we delete/stopwatching first the the filter in status-react and then ask status-go to remove the filter. For a public chat we always remove, for a one-to-one we remove only if the user is not in our contacts, or in a group chat or we have a chat open. Negotiated topics are never removed, as otherwise the other user won't be able to contact us anymore.
On stopping whisper we don't have to ask status-go to remove filters as they are removed automatically.
Some more logic can be pushed in status-go, but that will be in subsequent PRs.

This PR is part of network incentivisation. It adds a way for a client
to pull nodes from a contract.
This is done by selecting the `eth.contract` fleet. If that is selected
on login it will fetch nodes from a contract and pass them to status-go.
If these can't be fetched, it will default to `eth.beta`.
Currently contract information are hard-coded, but eventually the user
will be able to add their own (probably).

Currently we use a single topic for discovery.
This provides the best obscurity at the cost of bandwidth, as a message
sent on the discovery topic will be received by any peer.
This PR changes this behavior and start listening on a partitioned
topic.
Each pk will be hashed to a limited number of topics.
Everytime someone is in a conversation with someone from another topic
they will have to listen as well to avoid loosing obscurity, because we
only forward messages that we also advertise in the bloom filter.
The choice for the number of partitions depends on 2 factors:
1) The expected number of users using the network
2) The average number of contacts each user
Any change to the discovery topic will need to be split across 3
releases, to avoid breaking compatibility:
1) Listen to the new and old topic, publish to the old topic
2) Listen to the new and old topic, publish to the new topic
3) Listen to the new topic, publish to the new topic
This is step 1.

This commit moves group chats to their own topic, based on the randomly
generated chat-id. It falls back on the discovery topic for those peers
who we can't fingerprint the version, for backward compatibility.
Members will now have to explicitly join a group chat to start receiving
messages from it.
Messages are still sent to users who have not joined for backward
compatibility.
Group updates are unaffected.
The bug was introduced in #7055.
`message-type` was stored and used instead of `content-type` which
caused incorrect displaying of the last message preview if the one was a
command.
This commit changes the way how keys are restored:
1. batch of `ssh.addSymKey` requests for all sym keys is sent at once
2. `:status-im.transport.core/sym-keys-added` event is dispatched with
results of all successful `ssh.addSymKey` calls
3. filter is created via `ssh.newMessageFilter`
4. `:shh.callback/filters-added` event is dispatched with all added
filters as a parameter
5. profit
In ideal case only 2 `re-frame` events are dispatched.
In order to get `:last-clock-value` one extra query was executed for
each chat during initialization.
Implementation:
- `:last-clock-value` field was added to `chat` entity
- this field is updated when the message is sent/received
- extra query was removed
The last messages of the chats are necessary to properly show the chat
list, which is shown right after signing in. Before this commit, the
last message was retrieved as one of 20 last messages fetched for each
chat.
Implementation:
- `:last-message-content` and `:last-message-type` fields were added to
`chat` entity
- both fields are updated when messages are received/sent
- loading of the last 20 messages for each chat was removed as
initialization step
This commit changes the way how/when the node is started/stopped:
1. `node` is not started on the app startup
2. When the user presses "Sign in" button the node is started
with user specific configs (`InstallationID`, custom bootnodes, etc),
and only after that `Login` call is performed.
3. When the user creates a new account, at first the node is started
with default params (the same as would be used when user signs into
the app after account creation whithout changing any setting), then
`CreateAccount` call happens, then `Login`.
4. When the user restores their account, the flow is the same as `3`
but with `RecoverAccount` instead of `CreateAccount`
5. When the user logs out the node is stopped. That's it.
We now check that we are only connected to some `peers` instead of using `NetInfo` from `react-native`.
This is because it has been reported to be quite flaky at times, not reporting online status after sleeping, and for privacy concerns (on ios it pings `apple.com`, on desktop `google.com`).
Adds a new banner `Wallet Offline` and change `Connecting to peers` to `Chat offline`.
A message will be marked as `Sent` only if it made it to the mailserver you are connected to, which will increase the guarantees that we can make about a message (if you see it as sent, it has reached at least a mailserver), this has the consequence that:
- If you are not connected to any mailserver or the mailserver is non responsive/down, and you send a message, it will be marked as `Not sent`, although it might have been actually made it in the network.
Probably this is something that we would like to communicate to the user through UX (i.e. tick if made it to at least a peer, double tick if it made to a mailserver )
Currently I have only enabled this feature in nightlies & devs, I would give it a run and see how we feel about it.

Implementation:
1. `transport.utils/message-id` function is called only in three places now
and accepts `from` and `raw_payload` as parameters.

2. This means that for wrapped private group chat message
the raw payload of `GroupMembershipUpdate` is used.
We add syncing of account fields in pairing messages (only photo-path &
name for now). Also a sync message is sent each time we send a
contact-update, to keep other devices in sync. The change is compatible

Before we fetched ALL user-statuses with `status=received` (which means that
a message hasn't been seen), iterated them, grouped by chat and then stored
`message-ids` of these `user-statuses` in chat's `:unviewed-messages` key.
This commit introduces :unviewed-messages-count field in chat entity.
That means that there is no need to iterate `user-statuses` in order to count
a total number of unviewed messages, it is always stored along with chat.
In the rest of it, the difference is only that chat's db record should be
updated each time when unviewed messages are seen.
Go blocks parse try catch blocks and turn them into event
dispatches. This captures the original intent of the code to catch
errors and terminate the current async worker execution.

The reason it has been added to the map instead of augmenting transit is
that it would simplify the calculation of `message-id`, which in this
