The manpage was out of date and was missing a BUGS section. The `--help` output
of MaxScale wrongly stated that the default is to log to shared memory as did
the documentation.
The current implementation of the session timeout functionality is not safe to
use. Added a warning to the documentation and disabled the code. If the user
tries to use it, a warning is logged.
The documentation for readwritesplit now clearly states that only connections
from MaxScale are taken into consideration when slaves are being selected.
The limitation with readconnroute and LONGBLOB is only when data is being sent
from the client to MaxScale. The client can still query for LONGBLOB data
without any side-effects.
Changed default number of threads to 1 instead of autoconfigured value and
added a new `auto` variable which enables autoconfiguration of thread count.
The number of threads used when autoconfiguratio fails was changed from 4 to 1.
The default value of using N threads where N is the number of CPU cores was
not optimal as the possibility of rescheduling was higher the more utility
threads there were. Due to this, N-1 is deemed to be the better autoconfigured
value for thread count.
The Galera tutorials were very similar to the MySQL Replication ones with the
only difference being the configuration file creation. The tutorials were split
into smaller parts which are now referred to in the main MaxScale tutorial.
Renamed MaxScale-and-Master-Slave-Replication.md to MaxScale-Tutorial.md since
the tutorial wasn't only about Master-Slave replication and included the links
to the Galera tutorials.
The integration of the PCRE2 library into the regexfilter caused the
substitution rules to change now that it actually works and this needed
to be mentioned in the release notes.
Also fixed some minor things like links.
