The current implementation of sortOrder can be made way more easier now
by just keeping the sortOrder of the list
and the timelineFragments in the hiveStore. This needed a huge
change but mostly removes a lot of code which can be done
way more easy now. This also needed some rewriting of the setState logic and changes to
the prevEvent calculation. This solution should also be more stable.

Normally we do not need a workaround here at all but we had
one in the displayname calculation for
historical reasons. A "good" server should always send the mHeroes correctly.
Instead of removing this workaround completely we do a compromise and implement a more
lightweight alt behaviour by just saying that in a DM room with no
heroes, the directChatMatrixId will be used. This is the same behaviour like in Element
and needs way less lines than before and also covers the avatar
calculation. For Synapse we seem to not need this but for Conduit it
might be helpful.
As it turns out, some of the code set the prev_batch for rooms too
early to an empty string. For synapse this means "request from the start",
for conduit it is just an error. This commit fixes that by never resolving
null --> empty string, but instead throw an error.
The old mentionMap was very inefficient to build and scaled badly with
room member size. This resulted in noticable lag when sending any message
in a large room, no matter if it contained a message or not.
Now, the algorithm is severly optimized and mentions (and emotes) are
only loaded when actually used.
Using JoinedRoomUpdate() in a fake
sync for archived rooms when requesting
the history leads to the problem that
the room is stored as a joined room
in the store which is wrong.
This PR adds support for nicer mentions in markdown: You can now
fetch the mention string of a user with `user.mention` which is
human-friendly (typically contains the display name), which will get
properly pillified upon passing through the markdown parser.
