Provide a way to configure (at compile time) message and queue sizes.

Browse Source 
This patch makes it possible to override the following #defines:
MESSAGE_SIZE_MAX
MESSAGE_QUEUE_MAX
SIZEQUEUE
FLOW_CONTROL_ENTRIES_ENABLE

If MESSAGE_SIZE_MAX is defined as 1024*64 (64K) and
MESSAGE_QUEUE_MAX defined as 512 you can change corosync's
memory footprint from ~48M to ~8M

So if you define MESSAGE_QUEUE_MAX, the queue size will
not be based on the message size any more.

To use this define the defines on the command line:
make CFLAGS="-DMESSAGE_SIZE_MAX=1024*64 -DMESSAGE_QUEUE_MAX=512"
