- update to 2.0.15:
* Deleting the group configured as the anonymous group in the Dynamic Security
plugin, would leave a dangling pointer that could lead to a single crash.
This is considered a minor issue - only administrative users should have
access to dynsec, the impact on availability is one-off, and there is no
associated loss of data. It is now forbidden to delete the group configured
as the anonymous group.

MOSQ_EVT_MESSAGE.
* Fix bridge `restart_timeout` not being honoured.

MOSQ_EVT_MESSAGE event.

Closes #2404.
