This commit replaces the "mayWrite", "mayRead" and "checkPermissionOnNote"
functions with one that returns a sortable permission value.
This is done because many places in the code need to do actions based on the fact if
the user has no, read or write access. If done with the may-functions then the permission
data need to be looked through multiple times.
Also, the whole check code is split into more functions that are tested separately and make it easier
to understand the process.

By storing the ydoc state in the database we can reconnect lost clients easier
and enable offline editing because we continue using the crdt data that has been
used by the client before the connection loss.
