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.

Patch fixes situation, when user want to change warn signal after
call of sam_register function. This was not possible, because parent
process never got new value from child.

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.

Ability to in-memory storing of user data which survives between
instances of process.
Also ability needed ability for bi-directional communication between
child and parent is added.

Add support for MESSAGE_REQ_CPG_FINALIZE message. This will allow us
remove cpg_pd from list of active connections, and remove problem, when
cpg_finalize + cpg_initialize + cpg_join can result in CPG_ERR_EXIST
error.

This patch solves library waiting on sem_wait. It doesn't
solve all other problems, which can make corosync not
to exit (malloc race, global lock deadlock, ...)

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.

This adds the following option to configure:
--enable-small-memory-footprint
When enabled the following defines are set
to reduce the overall memory footprint.
MESSAGE_SIZE_MAX=1024*64
MESSAGE_QUEUE_MAX=512
PROCESSOR_COUNT_MAX=16
IPC_REQUEST_SIZE=1024*64
IPC_RESPONSE_SIZE=1024*64
IPC_DISPATCH_SIZE=1024*64

This functions allows iterate available cpg groups
and their members. API is modelled like ckpt iteration
functions.

Attached patches handle NULL callbacks in *_initialize
and *_dispatch. Handling is same as in quorum service. Now, when
callback is NULL -> no memcpy -> instance callbacks will have all
items set to NULL and in *_dispatch function is not called.
It changes cfg so now we are using continue instead of exit.
