Add shared memory page reserve for Rock and check page availability before IO.

The patch adds a shared memory page reserve for Rock (any IPC IO in
general) that can not be used by the memory cache.  Also, Rock checks
if there are free pages available before trying to do IPC IO (both
read and write).  This allows to fail early for cache reads and go
MISS route.
