* Replace lines/messages with helper class to synchronize state between
IChatLog and ChatLog more easily
* selection indexes have been replaced with ChatLine::Ptrs, this is to
ensure consistency while the view slides around
* This has another benefit of removing all the code that has to
manually slide the selection boxes around
* Replaced all insertion/removal functions with single "insertAtIdx".
This helps ensure that mappings between ChatLogIdx and position within
the view are captured correctly as items in the view slide around
* workerTimeout replaced with more generic name "renderFinished" that is
used in synchronous and asynchronous paths
* Removed unused function ChatForm::insertChatMessage
* Re-implemented "Go to current date" with new ChatLog APIs
* Removed unused GenericChatForm::addSystemDateMessage. This is handled
by ChatLog now
* Resolves#6223
* Resolves#5878
* Resolves#5940
* Simplifies reasoning about who owns what functionality between
GenericChatForm and ChatLog. GenericChatForm is now just a layout
class and ChatLog handles all interactions with retrieving and
displaying messages from the model
* Reasoning for work is described in more detail in #6223
This allows leaf classes to update independently when the GUI has changed themes, without
their parent having to call updateTheme() manually.

Enable warnings for both. Favour casting to signed rather than casting to
unsigend for comparisons. Per isocpp's core guidelines ES.102, signed
arithmetic gives more expected results. If we need one extra bit of range,
using longer signed types achives that.
Fix#6010Fix#6012
Message caching is handled by SessionChatLog in memory even when history is
disabled. ChatLog doesn't need to worry about how the messages its rendering
are being stored. Dynamic loading up and down in chatlog is sitll functional.
This commit fixes the behavior when a message is received while the
chatlog is scrolled to the bottom. With this change, the chatlog will
stick to the bottom when it is scrolled all the way down. If it is
somewhere in the middle (e.g. for search) the chatlog will not change
its position.
The previous implementation of hiding the date line would cause 100% cpu
usage. When the date line was shown it would hide the top line, causing
the date line to be hidden again due to a state change in which dates
was visible.
This is a minimal patch to work around the issue by pretending the line
covered by the date line is the first visible line when the dateline is
shown
Fixes#5620
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.
