Print memory usage

[vasdommes]

in debug mode:

• sdpb: print MemAvailable, GB and MemUsed, GB (= MemTotal - MemAvailable) from /proc/meminfo at each timer start, e.g.:

0 run.objectives MemAvailable, GB: 62.6031
0 run.objectives MemUsed, GB: 188.866

• sdp2input: print matrix sizes and RAM estimates, e.g.:
