There were too much false positives with passive mode rrp when high
number of messages were received.
Patch adds new configurable variable rrp_problem_count_mcast_threshold
which is by default 10 times rrp_problem_count_threshold and this is
used as threshold for multicast packets in passive mode. Variable is
unused in active mode.

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.

Some switches delay multicast packets vs the unicast token. This patch works
around that problem by providing a new tuneable called miss_count_const. This
tuneable works by counting the number of times a message is found missing
and once reaching the const value, marks it as missing in the retransmit list.
This improves performance and doesn't display warning messages about missed
multicast messages when operating in these switching environments.

The UDPU transport is useful for those deployments which can't use multicast.
UDPU works by using UDP unicast, which is fully supported by every switch
manufacturer by default and doesn't rely on a functional IGMP implementation.
An example of the UDPU transport is contained in the corosync.conf.example.udpu
file which shows a 16 node cluster. This file should be copied to each node
in the cluster and IP addresses changed as appropriate.
Amended to remove dead udpu REUSEADDR socket option.

Patch add support for Confdb integration with SAM. It's now possible to
use SAM_RECOVERY_POLICY_CONFDB as flag to previous policies.
Also new function sam_mark_failed is added for ability to use RECOVERY

integration with corosync watchdog)
Patch also makes SAM thread safe.

The flight recoder buffer size as specified in LOGSYS_DECLARE_SYSTEM
or _logsys_rec_init was expressed in number of ints. A developer asking
to allocate 512K would get a 2M allocation on a machine with sizeof(int) = 4.
This is confusing and the patch addresses it:
- rename rec_size to fltsize for external API (no type change),
because rec_size is used many times internally for other reasons
and it can be confusing.
- rename size to fltsize in _logsys_rec_init.
- document what we allocate and why.
- swap comments around to match the code.
- introduce a simple macro to perform rounding (stolen from linux-2.6.git).
- start shaping fdata header to better handle dynamic values:
* write the flt_data_size as first unsigned int the header.
* change corosync-fplay to read the value and alloc the right amount
of memory instead of hardcoding it again.
