Zdenek Kabelac ebad057579 vdo: check vdo memory constrains
Add function to check for avaialble memory for particular VDO
configuration - to avoid unnecessary machine swapping for configs
that will not fit into memory (possibly in locked section).

Formula tries to estimate RAM size machine can use also with
swapping for kernel target - but still leaving some amount of
usable RAM.

Estimation is based on documented RAM usage of VDO target.

If the /proc/meminfo would be theoretically unavailable, try to use
'sysinfo()' function, however this is giving only free RAM without
the knowledge about how much RAM could be eventually swapped.

TODO: move _get_memory_info() into generic lvm2 API function used
by other targets with non-trivial memory requirements.
