Zero element array behavior is very different from normal array or
pointer. This behavior is root of problem in not returning correctly
filled array of addresses. This appeared only in rrp mode, where more
then one address is returned.
All memcpy's are now correctly converted to copy pointer to char.

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.

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.

Fixes rhbz#499918
Functions from ckpt library (like aCkptCheckpointOpen,
saCkptSectionIterationInitialize, ...) internally uses corosync functions
reply_receive, reply_receive_in_buf, ... This functions are included in
coroipcc.c source file and uses global static variable ipc_hdb.
Without patch, coroipcc is linked to shared library (libcoroipcc.so) AND linked
with every corosync libraries (like cpg, ....), so global variable ipc_hdb is
included not only in libcoroipcc.so, but also in libcpg.so, ...
dlm_controld has function retrieve_plocks, and whole binary is linked with
libcoroipcc and libcpg. So ipc_hdb is included TWICE (so has TWO addresses).
Main problem causing the bug was, that reply_receive uses address from one
library, and reply_receive_in_buf uses other. This confuses check of hdb_get
function.
After removing linking of coroipcc.o to cpg, and rather use of dynamic version,
(this means, there is only one instance of ipc_hdb) problem disappeared.

strstr_rs used strdup and didn't handle failure. This change removes

passed a string of length 1 as the second argument. This also changes
