Jan Friesse pointed out that bindnetaddr should be set to a host
address (as opposed to a network address) on hosts where multiple
NICs live on the same subnet. Add a comment to that effect to
the example configuration file.

It's nice to say people should read the man page. It's also naive to
assume that they always do. Include comments in the example config
file itself.

Change suggested mcastaddr to one in the 239.255.0.0/16
pseudo-subnet. Multicast addresses outside 239.x.x.x may be IANA
registered and can clash with other services present on the
network. Suggest an address defined as part of the multicast IPv4
Local Scope in RFC 2365.

Change the example configuration file so "bindnetaddr" has a value
that more obviously looks like a network address. So as not to have
people think they need to set an existing IP address here (and hence,
have non-identical corosync.conf files between nodes).

Previous default (50) was too low for most modern switch hardware. This
may trigger abort because the aru doesn't increase for 50 token
rotations combined with a defect in how failed to recv conditions are
handled. By increasing this tunable, the condition should no longer
trigger the errant code.

Fixes a problem where there are gaps in the recovery queue. Example my_aru = 5,
but there are messages at 7,8. 8 = my_high_seq_received which results
in data slots taken up in new message queue. What should really happen
is these last messages should be delivered after a transitional
configuration to maintain SAFE agreement. We don't have support for
SAFE atm, so it is probably safe just to throw these messages away. Without
this change, the new message queue on a new configuraton change is out of sync.

Rather than curiously disable RDMA support by default in configure and
enable it by default in RPM builds, streamline the default
configuration to always turn RDMA support off. It can be enabled in
RPM builds with "--with rdma".

For the case where _POSIX_THREAD_PROCESS_SHARED < 1, the code doesn't compile
for corosync v1.3.1. And when it does compile, it crashes on our system - our
version of uClibc seems to always expect a 4th arg. The man pages suggests
the 4th arg is optional, but does say: 'For greater portability it is best to
always call semctl() with four arguments', which is what this patch does.
Also removed semop as it's an unused variable.

On our system the expected buffer length is 256. This means calls to
getpwnam_r()/getgrnam_r() return ERANGE error and corosync fails to startup.
These 2 functions return ERANGE when insufficient buffer space is supplied.
Judging by the man page for getpwnam_r, the correct way to determine the
buffersize on any given system is to use sysconf().
