add CMA test

changes in v3:
- add forgotten void in the cma_test_errnos() parameters
- change branching based on program parameter
- make return right in place instead of setting ret variable and returning at the end of the function
- dont pass TEST_ERRNO, use TTERNNO in tst_*()
- no need to pass tst_exit as cleanup fn to SAFE_*() macros
- remove useless initialization of variables
- avoid indirection when copying parameters
- use /proc/sys/kernel/pid_max + 1 as invalid pid
- add missing munmap

changes in v2:
- dropped configure check as glibc wrapper calls syscall directly, and using syscall(2) we can test also when glibc wrappers are missing
- added simplified process_vm.h

CMA (cross memory attach) feature introduced 2 new syscalls:
process_vm_readv
process_vm_writev

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].
