Fix#3124Fix#3004
Instead of loading a set 7 days of history. Better performance when there are lots of messages, and better context when friends haven't talked in over a week.
Removed historyBaselineDate, introduced in deb8440c6a to fix duplicate messages, but duplicate messages were very likely fixed by https://github.com/qTox/qTox/pull/4607.
Also refactored history loading.
Since real offline message reliability issue was fixed in PR #4607, now removing all the workarounds that had been added. Offline messages are now sent as soon as we see our friend come online, and at no other time. Fixes 2 minute wait time before attempting to send if message is entered while you or friend is offline, removes 2 minute constant retry timer, removes 250ms delay between seeing friend come online and sending offline messages.
Fix#4799
For every call was created new connection. First call was success. The second
call leaded to double answer: after the second core removes 'friendNum' from
'calls' list and cancels call. The third call leaded to triple answer, where the
first two same as before and the last one - tried to answer on call with removed
'friendNum' => assert failed.
Before we would set the video bitrate to 0 if sending an audio-only call, but we would still set the video bitrate to default when receiving an audio only call. In bad network conditions, this caused tox to ask us to decrease video bitrate in audio-only calls.
Revert needed, since otherwise there is no way to do automatic sorting
of includes.
Also reverted change to the docs, as leaving it would make incorrect
docs.
In case of conflicts, includes were sorted according to the coding
standards from #3839.
This reverts commit b4a9f04f92.
This reverts commit 5921122960.
Call buttons would be enabled but non-functional if you were looking at a friend who was offline. We now check if the friend is offline and disable the call buttons if so.
