This resolves a couple of doxygen warnings. First, the group needed a
name. Second, all of the functions in the file were added to the group
but doxygen complained about the lack of an end to the grouping.

This prevents a shared mem leak if corosync dies while clients
are connected.
Calling cpg_finalize() did not release the shared mem as
coroipcc_msg_send_reply_receive() returned an error and
thus coroipcc_service_disconnect() did not get called.

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
policy together with confdb and get expected results (specially with
integration with corosync watchdog)
Patch also makes SAM thread safe.

This patch unify behaviour of SYS V semaphores and POSIX semaphores.
POSIX semaphores never return CS_ERR_TRY_AGAIN on EINTR and keeps
waiting. This was fixed for SYS V semaphores in rev. 2303.
Another change is to remove very small probability of hung forever in
coroipcc_dispatch_put.
Last change is removal of duplicate code by adding ipc_sem_wait function.

Patch adds integration of SAM and quorum, so it's now possible to use
SAM_RECOVERY_POLICY_QUORUM_QUIT or SAM_RECOVERY_POLICY_QUORUM_RESTART
recovery policy. With these policies, sam_start will block until
corosync is quorate. If quorum is lost during health checking, recovery
action is taken.

Old code in coroipcc doesn't handle POLLNVAL. It can happen, that some
applications (for example fenced) will stuck forever.
Also poll result is now handled more correctly.

Patch adds new function to initialize cpg, cpg_model_initialize. Model
is set of callbacks. With this function, future addions of models
should be possible without changing the ABI.
Patch also contains callback in CPG_MODEL_V1 for notification about
Totem membership changes.

Add support for MESSAGE_REQ_CPG_FINALIZE message. This will allow us

The SAM library provide a tool to check the health
of an application. The main purpose of SAM is to restart
a local process when it fails to respond to a healthcheck
request in a configured time interval.
