Cross Memory Attach

"The basic idea behind cross memory attach is to allow MPI programs doing
intra-node communication to do a single copy of the message rather than
a double copy of the message via shared memory." [1]

This patch series is introducing the initial structure under syscalls/cma
and first test to check various errno codes as described in proposed man
page [2].
