Previously, we were incrementing mentions one-by-one
all concurrently in an unbounded fashion.
This would cause a big spike in memory usage if there
were an `@all` mention in a large channel.
We fix this by changing the SQL query to take all userIDs
at once.

* deadcode: remove UpdateChannelLastViewedAt
* deadcode: remove ThreadStore.(Save(Multiple)|Update|Delete)
* deadcode: followThead in App.MarkChannelAsUnreadFromPost
* document ThreadMembership, Thread structs
* maintain LastUpdated consistently
Whenever we touch a `ThreadMembership` record, we should be setting `LastUpdated` to the current timestamp. The mobile client relies on this to detect changes to these records.
* simplify: never updateThreads from `App.MarkChannelAsUnreadFromPost`
Change all invocations of `ChannelStore.UpdateLastViewedAtPost` from `App.MarkChannelAsUnreadFromPost` to pass `updateThreads` as `false`. When `ChannelStore.UpdateLastViewedAtPost` was invoked with `updateThreads` as `true`, it would in turn call `ThreadStore.UpdateUnreadsByChannel` but pass `updateViewedTimestamp` as `false`. This effectively updated the `LastUpdated` field of the corresponding thread memberships but never touched any of the actual data (such as `LastViewed`).
The overall CRT feature continued to work, because `App.MarkChannelAsUnreadFromPost` directly updates the relevant thread memberships via `ThreadStore.MaintainMembership`.
* deadcode: updateThreads in ChannelStore.UpdateLastViewedAtPost
* simplify: never updateThreads from App.SendNotifications
Change all invocations of `ChannelStore.IncrementMentionCount` from
`App.SendNotifications` to pass `updateThreads` as `false`. When `ChannelStore.IncrementMentionCount` was invoked with `updateThreads` as `true`, it would in turn call `ThreadStore.UpdateUnreadsByChannel` but pass `updateViewedTimestamp` as `false`. This effectively updated the `LastUpdated` field of the corresponding thread memberships but never touched any of the actual data (such as `UnreadMentions`).
The overall CRT feature continued to work, because `App.SendNotifications` directly updates the relevant thread memberships mention counts via `ThreadStore.MaintainMembership`.
* deadcode: updateThreads in ChannelStore.IncrementMentionCount
* fix & rename ThreadStore.UpdateUnreadsByChannel
Rename `ThreadStore.UpdateUnreadsByChannel` to `ThreadStore.UpdateLastViewedByThreadIds`, making it unconditionally set the `LastViewed` for the given threads (as well as `LastUpdated`).
All previous invocations of this method that passed `updateViewedTimestamp` have been previously removed.

* MM-36589: provide previous values for unreads
To successfully figure out the new counts of mentions or unread replies
for CRT we need to provide previous values alongside with the new.
This is needed so we'll know how many to subtract from the total.
This commit provides those numbers upon publishing websocket ThreadUpdated
and ThreadReadChanged events.
* Fixes errors
* Removes unneeded lines
* Adds GetThreadUnreadReplyCount store method
Uses the new store method to get unread replies instead of
GetThreadForUser.
* Tests, and some changes
- Adds api4 tests to test ws events
- Uses sqlx instead of gorp for new store method
- Fixes case where previous_unread_replies could be a negative value
* Refactors tests and adds more cases
* Fixes previous and current unread counts for commenter
When a user posts a reply to a thread the unread counts had a couple of
issues.
UnreadMentions where not zeroed out, and previous unread counts where
not set correctly.
This commit tries to fix that by marking the thread as read for the
current poster after we set previous unread counts to the websocket
event data.
Also MaintainMembership should zero out UnreadMentions when we are
setting the thread as read.
* Oops
* Fixes tests by updating when maintaining membership
OK, so some tests broke because we zero UnreadMentions in the membership
when we UpdateViewedTimestamp, since the new timestamp is always now.
Some tests broke because MaintainMembership for the commenter so that
the thread is read each time commenter posts moved further down in the
SendNotification method.
BOTH those test cases are fixed with this commit. To be sincere though I
don't understand why the second one is fixed by this.
* SystemAdminUser was not part of the channel
Some tests are failing because SystemAdminUser is not part of the
team and channels.
This commit adds user to team and channels, in an effort to fix
api4/user_tests
* Fixes tests
* Fixes tests
* Addresses review comments
* Fix if clause

We throttle the concurrency limit in maintaining thread membership
for a given thread using a counting semaphore. The limit is currently
8 which is a decent number to start with.
On some more thinking, it would be even better if the sql query
could be modified to support batch updates.

* Fixes race condition in notification.go
Appending is not thread safe, this commit makes followers a map
so we can add new followers from autofollow, and then adds those again
to followers.
* Fixes race condition
* CRT: desktop thread notifications
* Fixes go lint
* Adds default for desktop CRT notifications
* Adds email and push notifications for CRT threads
Adds user ids of thread followers with CRT to crtMentions so they will get
notified appropriately.
* Minor change
* Refactor a bit
CRTMentions.addMention had a bug on the return and de-duplication.
This commit fixes duplicate notifications by looking up if the user is to be
notified on CRT on both email and push notifications.
* Minor refactor
* Changes according to review comments
- Fixes adding to followers a user that had explicitly unfollowed a
thread.
- Simplified send email according to email_threads option
- Send mentions and followers in separate arrays via the websocket
- Fixes push notifications message for push_threads
* Adds a comment on a buggy use case
* Updates comment to correct ticket link
* Fixes when user notifications is set to all
There was a bug where if user had set notifications to all
then they would receive desktop notifications even for non following threads.
A similar bug existed in push notifications, where if a user has set it
to all the threads setting would still be considered.
This commit fixes that by adding users to notificationsForCRT
StringArray when they have the non thread setting to 'all'.
* Fixes notifications to users unfollowing threads
Users which had previously explicitly unfollowed a thread
should not receive notifications about those threads.
* Update store mocks
* Fixes push notifications for CRT
Push notification about replies for CRT users should have a title of
"Reply to Thread".
CRT users with global user setting to 'UserNotifyAll' should not get
notifications for unfollowed threads.
This commit fixes those issues.
* Fixes i18n error

* MM-37575: Handle nil value in override_username
Since props is a map[string]interface{}, an ", ok" check doesn't
really help because even if a key is not present, by default, a map
will always return the default value of the value, which would be a
nil interface.
So we can just check for the value of the map instead.

Summary
If a user has unfollowed a thread, another user's reply in the thread should not cause the first user to re-follow the thread. The first user will be re-followed if they are mentioned in the thread.
Simplify and make flexible the logic surrounding following and remove some duplicate code.

* MM-30882: Fix read-after-write issue for demoting user
In (*App).DemoteUserToGuest, we would demote a user, and then immediately
read it back to do future operations from the user. This reading back
of the user had the effect of sticking the old value into the cache
after which it would never be updated.
There was another issue along with this, which was when the invalidation
message would broadcast across the cluster, it would hit the cache invalidation
problem where an unrelated store call would miss the cache because
it was invalidated, and then again read from replica and stick the old value.
To fix all these, we return the new value directly from the store method
to avoid having the app to read it again.
And we add a map in the localcache layer which tracks invalidations made,
and then switch to use master if it's true.
The core change is fairly limited, but due to changing the store method signatures,
a lot of code needed to be updated to pass "context.Background". Therefore the PR
just "appears" to be big, but the main changes are limited to app/user.go,
sqlstore/user_store.go and user_layer.go
