this was another old onwire compat mode that is not useful anylonger.
we can safely move the new model by default.
According to Honza (real hardware 1 node testing) there are no
performance impact.
My tests (8 nodes VM cluster), there is up to 10/12% performance
improvements up to 1M packet size where old and new models are equal.
As a side note, nss still shows to be a performance loss on both
real and virtual hw (without any kind of nss hw acceleration).

Our preferred shared logging system is exported via the libqb library. As
a result, the corosync project no longer needs to export logsys.so and the
code can be directly included in the binary. The header file can also be
removed.

a memb_join operation that occurs during flushing can result in an
entry into the GATHER state from the RECOVERY state. This results in the
regular sort queue being used instead of the recovery sort queue, resulting
in segfault.

The recv_flush code is no longer necessary because of the miss_count_count
addition. It can in some cases lead to register corruption because of
interactions with -fstack-protector, the recursive nature of how this code
works, and interactions with the optimizer in some versions of gcc.
