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 change corosync shutdown process, so now:
- exit function of service engine is called
- all IPC connections are closed and removed from poll
- service engine is unlocked

This patch adds schedwrk_create_nolock, which will not call
serialize_lock before execution of callback.

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.

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.

most of the values in logsys.h are very useful for non logsys library
API users.
Allow to import them without sucking the whole lib.

LOGSYS_LEVEL_SECURITY is specific to corosync/openais and it
is used only in the totem configuration.
Drop the special case from logsys that's meant to be a generic
logging library and specify the correct equivalent for totem config.

This is needed as the objdb order will change as modules are loaded/unloaded and is
also set up to unload non-default services last (which is the opposite of what
something like Pacemaker needs).
In the worst case, the current behavior leads to cluster services (dlm, ocfs2, etc)
failing during shutdown. This patch also ensures that if, for example, cpg is unloaded
then anything that depends on it is unloaded first.
